19 June 2010 cruncher app updated
All cruncher/ogr apps are now updated to the latest stable distributed.net clients. There are bug fixes and new assembler cores available now for 32- and 64 bit systems which should improve speed on selected prozessors up to 30%. Now also a win64 app is avaiable. For a complete list of all changes check the forum.
12 June 2010 Euler625 new search
A new Euler application is now on test for Linx32 and Linux64 systems. To get the app you must enable test applications. Workunits are sometimes created for testing. The new Euler application searches now up to 250.000. There are 510.000 workunits in total. But first we need testers.
08 June 2010 Euler625 finished
The project is complete!
There are 181 solutions to (6,2,5) below 117649 ! We discovered 32 new solutions during this computation, and double-checked all the existing solutions. The only sad news is that we didn't find a solution to (6,2,4). Let's hope that the next project will discover one.
02 May 2010 Euler: new solutions
So far, two new solutions have been discovered:
927116+475676=830276+805566+598026+147006+140296
957136+630166=910806+794236+460746+96466+34026
We can expect 30 more solutions before the end of this computation. And we can hope for a (6,2,4)... For a more detailed description of the Euler project read the description in the forum.
24 April 2010 Euler: new project
Euler, a new project is now included in yoyo@home. The project runs currently as test project and has short deadlines. Euler (6,2,5) computes minimal equal sums of power 6. The project is dedicated to all those who are fascinated by powers and integers.
15 April 2010 ECM bug
Some ecm work units were underestimated in there memory requirements. They crashed mostly on Windows 32bit systems. This is now fixed in the wu generator. With the next batch of work units required memory is limited to 1800 M Byte. There will be of course a lot of work units which require much less memory. I just limited the top requirements.
I also hope that the long running ECM will sometimes lead to a new record ECM prime factor.
08 April 2010 Boinc community workshop
In 2 weeks the Boinc community meets for 3 days in Wieda/Germany. There are still some places available. More information in our forum. I hope to see some of you there.
29 March 2010 ogr@ps3
I hope sony just made an april fools joke on that: http://blog.eu.playstation.com/
PS3 Firmware 3.21 will be available this Thursday. It will disable the .Install Other OS. feature that was available on the PS3 systems prior to the current slimmer models, launched in September 2009. This feature enabled users to install an operating system, but due to security concerns, we.re now removing this feature.
For most of you, this won't have any impact on how you use your PS3. If you are one of the few who use the 'Other OS' feature, or if you belong to an organisation that does, then you can choose not to upgrade your system.
19 February 2010 subproject stats
For each subproject I added links to the stats pages of Free-DC. Now you can see per subproject the top teams and top participiants. Thanks to Free-DC to provide these stats.
14 February 2010 additional badges
I added some new badges to the system and hope they will be sufficient for the next years. Enjoy the additional levels and have fun ;).
16 January 2010 ECM: factor
The factor, which was found by Jeff17, is now recorded as the biggest one in the XYYXF ecm top record list.
14 January 2010 ECM: record factor
Jeff17 found a 57 digit prime factor for the XYYXF number 11063+63110. This is his 8. factor and our 3. in the 2010 top 10 list.
01 January 2010 yoyo@home under review
Currently, the RKN seal of approval reviews Yoyo@home. You all are invited to deliver your assessment and thus contribute to a meaningful result.
29 December 2009 ECM: record factor
Lazarus-uk found a 68 digit record prime factor which put us on the top of the top50 list of the lagest ever found gmp-ecm factors.
24 December 2009 EVO for Linux
We fixed a problem, that EVO was not finding it's result on Linux systems. Therefore we run a evo_B* series of short wus to see if now it runs properly. All old evo_A* wus were canceled. Please help to test and run some evo wus on Linux with wine.
I would like to wish all participants of yoyo@home a very Merry Christmas and a happy New Year! As always, many thanks for your continued support of the project.
THANK YOU! yoyo
19 December 2009 EVO for Linux
You can now run evolution@home also on Linux if you have installed Wine. Read more about it in the forum.
18 December 2009 ECM: new numbers
Some new work units starting with 'ecm_nr_' includes now a new type of number for which we search factors. We want to find factors for near-repdigit numbers. A near-repdigit number is a number whose all digits are the same except one digit somewhere.
18 December 2009 short server outage
Today we had a outage of 2 hours. The power supply unit of the server decided to finish it's work. We replaced it with a new one.
10 December 2009 ECM: 55 digit factor
Beyond found again a 55 digit number for the XYYXF ECM project. With this number yoyo@home users filled 50% of XYYXFs top20 ECM list.
06 December 2009 ECM: your factors
In your user page you can see how many factors were found by you. If you click on this number you see which factors.
28 November 2009 Muon for Linux
You can now run Muon also on Linux if you have istalled Wine. Read more about it in the forum.
23 October 2009 5. Pan-Galactic BOINC Workshop
Greetings from Barcelona. The workshop just finished. You can find the names of the attending people and the slides of the talks on the workshop web page. The remaining slides will be uploaded in the next days. There are also rumours, that something will be uploaded on YouTube and Flickr. We also made our first public presentation of our new RNA World project, which will go public in the next days. Currently it is beeing tested by a closed alpha test group. In the meantime the server is running well, produces some ECM factors and also the long running evo wus are processing well. Thanks for all your support, yoyo.
12 October 2009 ECM: XYYXF record factor
User Beyond found a 55 digit prime factor for XYYXF number 11691+91116. This number brings us again into the projects ECM record list.
03 October 2009 evolution@home
In the next days I will start creating evolution@home work units, which have doubled run times as the currently running evo wus. They have still no checkpoints.
27 September 2009 ECM
WUs in progress are no more aborted by project. I found a way to only abort wus which are not yet started if a factor was found and the result is no more needed.
26 September 2009 Subproject Signature
Free-dc.org created a signature picture with all your yoyo@home subproject stats. Just use this URL http://stats.free-dc.org/yoyotag.php?id=1&theme=1
id - your yoyo@home user id
theme - 2,3,4,5,6 are different themes.
Here is an example Thanks to Bok.
22 September 2009 ECM: XYYXF record factor
On 15. this month user asb2106 found a 55 digit prime factor for XYYXF number 14480+80144. This number brings us to position 4 in the projects ECM record list.
29 July 2009 Cruncher: faster OGR cores
I updated the Cruncher application to the latest distributed.net version. The new x86 clients contain three new OGR cores. Depending on your CPU type, the new cores may provide a significant speed improvement over the cores used in previous client versions. In the ppc versions some bugs were fixed.
09 Jun 2009 yoyo@home in the news
On 14th of June 09 yoyo and yoyo@home will be featured in a short presentation on grid computing in the German TV program 3SAT Neues at 16:30 GMT+1. While the main focus of this program will be grid computing in general, the special efforts of the volunteer computing community will also be featured.
17 May 2009 Muon stats page
On the new Muon stats page you can now see the progress of the running optimizations.
09 May 2009 Rechnkraft.net e.V. first scientific contribution
Hello,
the registered non-profit association Rechenkraft.net e.V. made a major step ahead and proudly announces a first contribution to a scientific article in one of the major microbiology journals (Molecular Microbiology). As the result of a cooperation project carried out with the work group of Prof. Dr. Umesh Varshney from the Department of Microbiology and Cell Biology at the Indian Institute of Science, Bangalore, India, we just published an article about the Impact of rRNA methylations on ribosome recycling and fidelity of initiation in Escherichia coli. Notably, one of the computer modeling figures computed for this article even made it to the cover image of Molecular Microbiology's May issue.
With this step, the volunteer computing association Rechenkraft.net left its first scientific footprints. We will further proceed to contribute and support world wide distributed and grid computing and, in addition to this, try to generate and evaluate some of the processed results by lab experiments where possible in the future. We are happy about each new member joining our association to support our efforts and, of course, donations are also welcome ;).
02 May 2009 ECM: ElevenSmooth
User [ESL Brigade] NaiV found a P43 that reduced the unfactored primitive of 26160+1 from C1142 to C1099. This is the second known factor of this primitive; the other known factor is a P15 also found by ElevenSmooth.
14 April 2009 ECM: ElevenSmooth
yoyo@home users found a P48 and a P50 for 23080+1, finishing the factorization of this primitive by leaving a P481. User jalmari found the P48 at 9:40 CET on Easter Sunday, then user Bent Vangli finished the number with a P50 at 12:20. No factors were previously known for this primitive. The factors were all confirmed prime with Dario Alpern's Java factoring applet. This is the sixteenth primitive for which ElevenSmooth has completed the factorization, and the fourth done by yoyo@home.
29 March 2009 ECM: OddPerfect, ElevenSmooth
Last week we extended the number range and run some test workunits with up to 85000 digits. Unfortunately in the first try the work generator was not able to handle such big numbers and greated wrong work units. We fixed it and run all the test work units again and found already some factors during the test. On some clients the big numbers crashed, mostly Windows. If you had ecm work units with exit code 195 (0xc3) and in stderr out you have app exit status: 0xc00000fdyou can help to find a solution for it.
We found also a P51 from 23360+1 leaving a P393 which completes the factorization of this primitive; a P8 and a P13 were known before the founding of ElevenSmooth. This is the largest factor ElevenSmooth has found by ECM, and this is the fourteenth primitive for which ElevenSmooth has completed the factorization.
23 March 2009 ECM: OddPerfect
Yoyo@home users found two new factors for 398581 factor chains. Many
proofs about odd perfect numbers are based on factor chains. Factor
chains based on 398581 are important because it is the only possible next
link for two chains. In a recently completed yoyo OddPerfect project, these were two of
eleven composite numbers whose factors would improve the best known
398581 chains. Thanks to the yoyo users for progressing this work.
William
19 March 2009 Graphs added
On the bottom of the server status page are now some graphs about average runtime, amount of unsent workunits and subproject flop distribution.
16 March 2009 ECM: Mac 64 bit
Now also a 64 bit Mac version is available. I think this is the first time ecm runs on a 64 bit Mac system. ECM developer had changed the assembler code to get it working.
14 March 2009 ECM: Mac version
A Mac version for x86 and PPC is now released. Thanks to Michael Tughan for this. Please test and report the results in the forum.
08 March 2009 ECM: extensions
I enlarged the number ranges for ECM now. In the last weeks I made much tests with large number and enhanced runtime prediction formulas and introduced also formulas for dynamic memory prediction. This allows us to run also numbers for the Mersenneplustwo Factorization Project. These numbers runs much longer than numbers before and consumes up to 2GB of RAM. If your system does not have the required amount of memory free Boinc will not download or start these work units.
24 February 2009 OGR: OGR-26 finished, -27 started
OGR-26 is now officially completed. I cancelled all remaining OGR-26 wus. Wus which are now sent are OGR-27 wus.
Due to variations in complexity, distributed.net expects that OGR-27 will take
significantly longer than OGR-26 did. It is difficult to provide a
precise estimate but one extremely rough guess is about 7 years,
assuming no increase in computing power and that the size estimation
sampling reflects the entire stubspace.
There is one thing that is different with OGR-27 than with
previous OGR projects: distributed.net is confident that we will discover a better
ruler for OGR-27 than the one which is known to be optimal currently.
23 February 2009 ECM: OddPerfect
This weekend yoyo@home finished work on a batch of small composites
and advanced a special project for Vanishing Fermat Quotients. We
factored a dozen of the small composites. The most fun was 158 digit
number for which we found two 40 digit factors. Only about 6 in 10,000
composites have two such factors, and even then we often miss one of the
factors until later.
Vanishing Fermat Quotients (VFQ) happen when, for primes p and q, q2
divides pq-1. Pace Nielsen has many cases are simplified when the
VFQs have two large factors, and the simplest way to verify that is to show
two large factors. yoyo@home has found four new VFQ factors so far.
16 February 2009 OGR: new versions
All Cruncher versions are updated to the latest 509 version of distributed.net client. Read in the forum about the detailed changes.
15 February 2009 ECM: ElevenSmooth factor found
Stefan Ver3 found a P37 factor from 215120+1 on Valentine's day. Two small factors were previously known; this reduces the composite cofactor from C2063 to C2026.
14 February 2009 OGR-26: End Phase
OGR-26 processed more than 94% and will probably finish this month. Much thanks to all Boinc crunchers. The Boinc Community reached #3 in distributed.net's team stats.
09 February 2009 ECM: OddPerfect
The largest work units have been looking for 55 digit factors of OddPerfect's
Most Wanted Numbers. This weekend we finished a heavy duty pass
through these without success. We had a 30% chance of finding a 55 digit
factor; there is a 20% chance that we missed a 55 digit factor. We will be
revisiting these numbers often checking for 55 and 60 digit factors.
Although it is disappointing to have no Most Wanted Factors, it's exciting to
be this thoroughly tested already.
The smaller work units have been looking for 45 digit factors in a batch of
small residual composites left over from previously factored numbers.
We've had better luck with these, finding several factors already. Behind
this batch there are several special projects in the queue.
04 February 2009 ECM: new projects
The ECM application is now connected to OddPerfect, ElevenSmooth and XYYXF. The currently running factorizations can be seen on this page. I'm also working on a page with all found factors.
20 January 2009 ECM: a regular application
ECM is no test application any more. It's now a regular yoyo@home application. Additionaly the deadline is increased to 5 days for new work units. Now also work units for ElevenSmooth are in the queue.
18 January 2009 OGR: new win32 app
Cruncher 2.1 was updated to dnet version 508b which contains a new MMX assembler core. This improves performance by up to 30%. The progress indicator increases now by 14,3%.
17 January 2009 OGR: new PS3 app
Cruncher 2.10 runs OGR now also on all SPEs. This should drastically increase the performance of the PS3.
17 January 2009 ECM: numbers for OddPerfect
OddPerfect has many tasks that we work on from time to time. The variety of easy and hard tasks keeps things interesting. Yoyo@home's BOINC ecm has already pushed several tasks beyond where William expected to get in all of 2009. In addition we've had the fun of being major contributors to Paul Zimmermann's the Top 10 Factors of 2009. Read the whole story ...
10 January 2009 ECM: test status
The ECM test runs quite good. 64 bit hosts are much faster than 32 bit hosts. Our test found already some factors and we are listed in the 2009 ECM Top 10.
If somebody is able to compile on Mac contact me. In this case we could release also a Mac version. The boinc lib, the wrapper, libgmp and ECM must be compiled and optimized.
07 January 2009 OGR-NG: status
OGR-26 made significant progress in the last month. Over 50% is completed. We will probably finish this project in March.
29 December 2008 ECM: new subproject
ECM is the next app which is wrapped. Ecm is a program for Elliptic Curve Factorization which is used by a couple of projects to find factors for different kind of numbers.
Some test wus for Linux 32/64 are currently running. To participate on the first tests you must enable test applications in your yoyo@home preferences. Please report problems, suggestions or even success in the forum.
03 December 2008 OGR-NG: small application update
Now are all old ogr wus, which contained only 2 ogr, are over. Therefore I update job.xml to now contain 4 tasks. The progress indicator increases now in 4 steps. To get closer to the PS3 needs I also increased the number of ogr contained in one boinc wu to 7.
30 November 2008 Badges
Since round about one week I'm collecting credits per user and sub project. You will be rewarded with a badge if you reach a certain level of credits per sub project. The following levels exists currently:
Bronze - 10.000 credits
Silver - 100.000 credits
Gold - 500.000 credits
Master - 1.000.000 credits.
Thanks to Rebirther for the work on the icons.
26 November 2008 Project Changes
In preparation to a PS3 version which uses also SPE I increased the amount of ogr which are in one Boinc wu. There are now 4 ogr in one Boinc wu instead of 2.
I also capture credits and number of wus per subproject for teams and user. If somebody want's to generate some nice statistics or signature pictures out if it these stats are exported here.
23 November 2008 OGR-NG: official relased
The OGR cruncher is now official released. I made also an update of the windows client to the latest version (507b) which was released by distributed.net.
21 November 2008 OGR-NG: Solaris Sparc64
I released also a Sparc64 beta client for OGR-NG. Please test and report in the forum if it runs.
20 November 2008 evolution@home
I created now all new evolution@home simulations. On the server status page you can now see how many workunits are available to finish the first basic goal of the new simulation series.
16 November 2008 evolution@home: new simulations
A new set of computing tasks is published today in order to further investigate how two different types of slightly harmful DNA changes interact with each other's evolutionary behaviour in a population. The new workunits are named 'evo_A....'. Runtime is up to 2 days (on our 500MHz Pentium reference system).
07 November 2008 OGR-NG: new beta apps
I added beta applications for OGR-NG (ogr next generation). You must enable test applications to get them.
The effective search rate is actually more
efficient as these new applications are using an improved algorithm. The
new algorithm is named FLEGE (Feiri-Levet Enhanced GARSP Engine).
In technical terms, the number of elements in the
'choose lookup table' has been increased from 48K to 2M
elements. This optimization will significantly reduce the number of
nodes that we have to search through, sometimes a node improvement of
ten-fold or more.
Distributed.net estimates that OGR-26 will take much less time to complete than
OGR-25 and will probably be more similar to OGR-24, in terms of
computational effort. Beyond that, distributed.net is looking forward to OGR-27 and
OGR-28 because the current solutions to at least one of the two is
very likely not optimal. OGR-26 is on the way and must be done first
since higher-order rulers depend on the proven optimality of previous
ones.
26 October 2008 OGR-25: Successfully Finished
The 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008.
19 October 2008 What next?
In some days ogr will be over. I would enjoy to start the discussion which project should be included next. If you also have contact to the authors of some projects, leave me a message. And of course if somebody is interested to help in the integration, contact me.
I also have some projects on my radar, but will not start the discussion with these ;). So discussion is reopend, give your suggestions in our forum.
12 October 2008 OGR: 0.15% left
Only 0.15% ogr left and we are going to finish the project. Therfore I encourage all users to use only small buffers. Otherwise the OGR would already have been crunched by somebody else and the result does not help the project to finish.
Some weeks ago I changed already some settings for OGR Boinc WUs:
deadline is now only 7 days, before it was 14 days
there are no resends anymore
only 1000 unsent WUs, before it was 5000
only 8 ogr in one Boinc WU, before it was 9
decrease of ogr in my dnet proxy from 50.000 to 20.000
04 October 2008 evolution@home has quantified Muller's ratchet in the worm C. elegans
The small worm Caenorhabditis elegans is known for his high rate of selfing that may make it susceptible to the operation of Muller's ratchet. Now evolution@home has found that this worm would indeed be in trouble if there were no processes that would counter genomic decay in this worm or if selfing was very old. See the full article here.
29 September 2008 OGR: 1% left
Less than 1.1% ogr left. The project will end in round about one week.
20 September 2008 OGR: 2% left
98% of all ogr workunits are finished. Our Final Push for ogr Race kicked the project a step forward. The predicted end date for ogr is now the 8 of October. Thanks to all racing teams for participation.
11 September 2008 OGR: 3.2% left
We made progress there are only 3.2% ogr left to crunch. 1 of October is now the predicted and date.
06 September 2008 OGR: 4% left
We made progress there are only 4% ogr left to crunch.
01 September 2008 OGR: 5.1% left
With the start of our race there are only 5.1% ogr left to crunch.
29 August 2008 workunit ID 1.000.000 finished
User dago.net finished workunit ID 1.000.000 yesterday, which was a OGR workunit.
24 August 2008 OGR: 6.8% left
OGR steps forward to its final goal. There are only 6.8% of work left until the finish line.
18 August 2008 Challenge: final push for ogr
Hello,
be prepared for the final push for ogr challenge".
This race starts at 1. September 0:00 UTC and ends at 15. September 0:00 UTC.
The team and user with the most credits in this period is the winner.
The goal of this race is to push the OGR project a bit to its final goal. Currently more than 90% are finished and we hope that the project will still finish in 2008. The OGR project searches for a optimal Golomb rulers of order 25.
We encourage each participant to enable only the cruncher application during the race and switch muon and evolution@home off.
14 August 2008 OGR nearly finished
The OGR subproject did some major steps in the last weeks, more than 92% are finished. The predicted end date is galloping towards us at a phenomenal rate. The 30-day prediction, which uses the stats from the last 30 days to project an end date, has decreased by 2.5 months in the last 3-4 days. It is very possible that this project could be wrapped up before the end of the month.
06 August 2008 1. yoyo@home birthday
One year ago the first ogr workunits were credited in distributed.net stats. It was a wonderful year. One year ago my goal was to learn how the Boinc server works and how an existing application can be wrapped into the Boinc world. Now, one year later, ogr, evo and muon are wrapped and all 3 applications are productive and provide more results to the projects than expected. So let us celebrate the first birthday of yoyo@home. The ogr project is now completed with more than 90% and the yoyo@home team is number 7 in the worldwide dnet team stats. It seems that ogr will finish in October 2008. Let us focus on ogr and make a great ogr end race to show the whole Boinc power to distributed.net.

23 July 2008 Muon simulates a new design
Since some days Muon simulates a new design. This lattice is an attempt to improve yield by adopting a "monolithic" design for the first 10 solenoids. All previous Muon lattices have left 50cm gaps between the solenoids for engineering reasons and for diagnostics to be inserted, but near the target it is becoming clear that the whole first few metres of the muon channel will be designed as a single module. This gives more options for magnetic field profiles in the important area immediately after the target rod, which Stephen Books is hoping can reduce the muon beam divergence further down the channel.
15 July 2008 evolution@home Boinc contribution
By now the BOINC system has contributed more CPU-years in results than all previous email submissions combined to evolution@home. yoyo@home has now reached 162.63 CPU years, since the BOINC scheduler started in Nov 2007. Thus, the BOINC contributions have overtaken the results submission by email for the first time. Read more about it on evolutionary-research.
29 June 2008 Screensaver
Cruncher and evo have now a screensaver. Many thanks to Alderan who played around with OpenGL.
26 June 2008 News in boincmanager
I played a bit around with sending news to the clients. You can now see 3 buttons in your boincmanager if you click on yoyo with the 3 most recent news topics.
07 June 2008 Interview with author of evolution@home
Some days ago I made an interview with Laurence Loewe, the author of evolution@home, about his project, some results, the integration in Boinc and the future of evolution@home.
23 May 2008 OGR-25 end prediction
OGR-25 is still predicted to be in 2008. Have a look to this prediction page where also the completion of all stubspaces is shown.
18 May 2008 Cruncher version 1.2x
I released a new cruncher version. Now the cpu time is stored at each checkpoint. The displayed cpu time in boinc manager should now not fallback so much after a restart. Report problems in this thread.
26 April 2008 faulty muon wus
Please cancel all muon wus with the name "muon_080425171315". These wus will not run.
11 April 2008 Evolution@home: work generator stopped
Evolution@home announced a new simulator to run new kinds of simulation. Therefore I stopped work generation for the existing simulator until the new one is integrated in yoyo@home to empty the evo queue. I hope it will not take a longe time until the simulator is released.
06 April 2008 Evolution@home: why are we still alive
The first results of evolution@home are now available for public download. Read more about "Why are we still alive?". By the way, evolution@home had its 7th birthday.
05 April 2008 Muon 1.07 released
I released a new version for muon which in avarage should be faster than before. Read about all changes here.
17 March 2008 Server problems solved
The server and mysql crashes in the past are now solved. The CPU fan was broken. Everytime the system gets high load it was to hot for the CPU and the system crashed. Mysql was the first part which crashed.
08 March 2008 New application
We test Muon as new application, thanks to Cody for coding the wrapper.
03 March 2008 Just a note
We host currently a German youth research project on the yoyo@home server. I do not know if this has influence to yoyo@home.
01 March 2008 mysql problems
We have strange problems with our mysql server. The server crashes very often and restarts, but after restart the Boinc server processes have problems. We are working on it.
14 February 2008 Future about evolution@home integration
Some news and future views about the integration of evolution@home are now posted in the evolution@home blog.
03 February 2008 Crash-Tour T-Shirt
Yes you were part of this crash and you can show it with this T-Shirt. A part of the money will be used to keep the server running.
02 February 2008 Server is back
The new server runs now without any big problems. In the first hours I will not send new work units because there are wus in the world which could be over the deadline. These would be resent by the feeder. So I give you a chance to empty your buffers and upload all wus.
31 January 2008 Server crash
Yesterday our small server was not able to handle all your request. The runtime of OGR WUs was getting shorter and shorter and all hosts requested more frequently new WUs and reported finished ones back. This leads to high traffic in the database and to out of memory on the system. This server also hosts the homepage, forum and wiki of the Rechenkraft.net association. To get them up again we immediately stopped access to yoyo@home. The server went back to normal forum and wiki processing.
Last night we analysed the problem and decided that we need more memory and a separation of yoyo@home and the rest of the rechenkraft.net page. Thanks to the support which I got in chat and to the donations, we now ordered a new server for yoyo@home.
Our new server is installed and got the yoyo@home backup but is currently not yet online. I think that workunits which reached the server will get credits, but it seems that there are a couple of WUs which were not properly uploaded. For these no credits can be granted. We hope to be online very soon.
26 January 2008 Linux 32 bit 1.09
Version 1.09 of cruncher for Linux 32 bit contains now the newest distributed.net client version 2.9015-504.
14 January 2008 new evolution@home wus
I created some new evolution@home workunits, which are now twice as long as before.
13 January 2008 new PS3 Cruncher
A memory corruption problem was recently detected in the PS3 version of the cruncher. Read more about it in our forum and report problems or even that there are no problems.
06 January 2008 new evo wus
I will create new workunits for evolution@home. The new workunits runs longer than before. Because of missing checkpoints I will grant 30% more credits for all credits which are higher than 100.
06 January 2008 1.04 of evolution@home
Version 1.04 will no more crash if the work unit restarts. But it starts from the very beginning, it does not resume the work unit.
01 January 2008 Evolution@home now productive
The evolution@home application is now productive. By default you will get now workunits from both applications. You can change these settings in your preferences.

27 December 2007 Fixed credits for evo
Fixed credits for evolution@home workunits are now in place. Report problems or questions in our forum.
26 December 2007 Best wishes
I wish you a merry christmas and a happy new year. Thank you for supporting yoyo@home and running to rank #25 in the distributed.net team stats.
yoyo
23 December 2007 Top 30 reached
The race between L'Alliance Francophone and SETI.Germany pushed yoyo@home in the top 30 of the overall distributed.net team stats. Thanks fellow crunchers for this christmas gift.
21 December 2007 evolution@home update
Short update information for evolution@home: In the last days I automated the sending of results to Laurence,
the author of evolutio@home. I sent round about 100MB of compressed data. He was on a conference and busy with preparations for it.
But now he reviews and imports the results. As next step I will work on fixed credits to aoid double computing.
I clarified the concept and have now an idea how it could be calculated. If both things are working I will switch from
beta to productive.
14 December 2007 7 times OGR output
Since some days a race between the #1 and #2 team is ongoing. Therefore the
OGR output povided to distributed.net
is now 7 times more than before. I keep a very close eye to the server to ensure everytime enough work units.
02 December 2007 Beta version of evolution@home for Mac
I released a beta version of evolution@home for Mac. Give feedback in the forum.
25 November 2007 Server status page
I added information on the server status page
to see for which application work units are available.
23 November 2007 1.02 beta of evolution@home
Version 1.02 runs additional to Windows XP also on Windows 2000 and Vista. It has also a progress indicator.
But it is hard to estimate the time to complete a workunit and also the progress. So it may happen that the
workunit finishes already at 50%. But anyway better than no progress indicator.
22 November 2007 First beta of evolution@home
The first beta of evolution@home is running and
it runs better than expected. The results contains already
real usefull simulations which will be send back to the author.
Thanks to rebirther for the logo update.
BTW: If somebody wants to develop
a nice screensaver send me a mail.
20 November 2007 New versions for Mac and Linux
To get rid of the sometimes appearing endless loop at 87% of the wu I created new versions for Intel and PPC Mac
and for 32- and 64 bit Linux. This problem happened for round about 10% of the work units on Mac and Linux.
20 November 2007 Backup
I implemented a database backup and some cleanup of all the generated log and statistics.
The server runs smoothly without any manual intervention. More than 100 days OGR are crunched for distributed.net.
In total individual and team stats we are in the top 100. On daily basis we are in the top 5.
I started now phase III, wrapping the next project.
06 October 2007 Statistics
After two month providing OGR back to distributed.net the yoyo@home Boinc wrapper team is on the
overall rank 157 of all teams in
distributed.net statistic.
OGR has now completed more than 72%
of its search space, predicted end is mid of 2008.
02 October 2007 64 bit Linux version update
Some volunteers reported problems on 64 bit Ubuntu. I hope version 1.08 now fixes this issue. This version is now a native
64 bit version.
30 September 2007 Free BSD version
Added a Free BSD version for Intel.
29 September 2007 Additional clients
Thanks to Dotsch clients for PS3 and Sparc Solaris could be added.
Please test and report success and problems in our forum.
A Boinc 5.11.0 client for Solaris can be
downloaded here.
27 September 2007 OGR project status
OGR has now completed more than 70%
of its search space. Some predictions predict the end for the mid of 2008.
16 September 2007 New validator
A new validator is in operation which grants credits based on calculated GNodes.
Quorum is now set to 1 and credits are granted immediately.
07 September 2007 Statistics
After one month providing OGR back to distributed.net the yoyo@home Boinc wrapper team is on the
overall rank 651 of all teams in
distributed.net statistic.
06 September 2007 Version 1.08
Suspend / resume did not work properly on Windows. This version solves the problem. If there a problems with
this version report it in our forum.
02 September 2007 Parameter for WUs changed
I increased the estimated fpops for a workunit 20 times. This should avoid to many downloads which can not fit the deadline.
For new workunits the deadline is increased to 7 days.
31 August 2007 Version 1.07
Suspend, resume, exit should now works properly in version 1.07.
Thanx to Codemann and scsimodo.
Please report problems in our forum.

14 July 2007 yoyo@home started
yoyo@home aufgesetzt. Workunits dauern z.Z. ca. 10 Minuten.
Wer unter Linux rechnet und etwas testen will schreibt mir eine email.
Ich richte dann einen Account ein. Es wird Uppercase gerechnet.
Die Workgeneratoren, Feeder und Assimilatoren laufen.
Der Server wird nur gelegentlich mal Online sein, ich hoffe so immer von 20:00 - 22:00
oder auch öfter, mal sehen. Nächste Schritte:
Forum bei RKN einrichten
wiki Seite anlegen, damit Informationen auch verfügbar sind, wenn der Server nicht läuft
Ansehen wie man fixed Credits gibt
27 May 2007 Erster Versuch
Erster Versuch einen Boinc Server aufzusetzen und zu lernen wie man die news schreibt.
