ECM memory usage calculation too low

[Crystal Pellet]

@yoyo: I already changed manually the memory bound to 3000MB and later to 3500MB. Both without success.
Now I've changed manually the maxmem parameter to 3000MB and (re)started a single mp-216091 task.
Within an hour I'll know if a 2nd ecm-process will start for the second curve.

Meanwhile I also started a task on Linux64 on a machine where a Windows task errored out.
However here the runtime will be ~3 times longer.

Also manual intervention with the maxmem parameter set to 3000 didn't succeed. Computation error again.

Two startings because I restarted Boinc after 1 minute, so it's still the 1st curve.

My test on Linux64 is OK. 2nd curve started. Estimated runtime in stead of ~5 hours for Windows now 14½ hours on Linux.

I increased the Boinc memory bound to 3GB now for this ecm_mp series. If this doesn't help I have to cancl them all. The -maxmem parameter should limit the memory consumption to 1,8GB but it seems not to work for this wus. I can't change it easy for existing workunits. But I will increase it in the wu-generator for the future.

Will these cause a 4GB quad to choke due to memory requirements? The earlier ecm_mp WUs worked fine on such a system.
A request for the "Results" page: could we have the "Show: All | In progress | Pending | Valid | Invalid | Error" sorting choices that are available in many projects?

Thanks!

This feature is already there. If i go to my "tasks" site, i have exactly these filters.

You can also test it outside of Boinc. Just create an empty directory. Copy ecm.exe and the "in" file to it and run ecm.exe. Since I do not have a win64 system just try it without the -k and -maxmem parameter and additional -v parameters and run:

Code: Alles auswählen

ecm.exe -v -v -v -v -nn -timestamp -chkpnt checkpnt -inp in 250000 > out

I'm not getting it in either my user results or results for a computer:

Where are you seeing those choices. Maybe it's not instituted for English?

I'm also missing the sort feature. But that wish/problem doesn't match this thread.

Yoyo, feel free to move that part of my post to another place if you like. Thanks!

Sorry, I was wrong. (I looked at the wrong project page.)

I reduced BOINC to 3 cores and started it in a DOS-box on a 50% slower AMD Vista64 machine.
I think it doesn't matter, Win7 or Vista, because I've also seen computation errors from others on XP.
Tomorrow (UTC) I'll see the outcome. I'm not sure how many curves will be run. I think only 1.

Standalone task crashed. Zipped out file has 672MB, where to post it?
