ECM memory usage calculation too low

#1 Ungelesener Beitrag von Crystal Pellet » 17.01.2011 16:44

wrapper: running ecm.exe (-v -nn -timestamp -chkpnt checkpnt -inp in -k 8 -maxmem 1800 250000)

During the last phase of the first leg out of 5, the tasks end in computation error, because the ecm process is demanding more than 1800 MB.
I've seen it wants to allocate at least 2100MB of memory.

Thanks for the hint. I set max_memory_bound for all these wus to 2200MB and changed also the wu-generator. If you download now these wus the maximum is 2200MB. I hpe this is sufficient.

The P216091-tasks are still ending into computation error at the end of the first curve.
In the client_state.xml the memory bound was 2200000000, but the command -maxmem parameter still is 1800?

wrapper: running ecm.exe (-v -nn -timestamp -chkpnt checkpnt -inp in -k 8 -maxmem 1800 250000)

The last task allocated 2216.420 kB memory, before it crashed.

Yes, -maxmem 1800 is still ok.This should limit memory consumption to 1.8GB.
I increased memory bounc now to 2600000000.

Now 4 results of a Linux 64 bit system returned successful.
Seems that the last memory bound increase solved it.
This means results downloaded after 17.1. 7pm UTC should be fine.

Ab welchem Ausgabedatum/Uhrzeit sollten die MP WUs wieder laufen (Änderung auf "memory bounc 2,6GB")? Denn die WUs die ich jetzt im Moment bekommen (Rechner 45435) gehen immer noch kaputt. Rechner ist ein Win64 mit 8GB RAM.

Bis denn dann, Grubix.

Maybe its a problem with the Windows app only. All my tasks ended with compute error even when downloaded after the timestamp mentioned above.

@Yoyo: Yesterday evening late (UTC) and this morning I tried running again these monsters ;)

As Curly said: All tasks are crashing towards the end of the first curve on Windows.

For testing I ran only one at a time (Quad-AMD, Windows7 64bit), combined with 3 simaps (low memory tasks).

When I have a close watch just before the crash, I notice that the allocated memory increased to >2200MB and the peak memory usage goes over 1800MB.

Could you try to increase the maxmem parameter?

Same here, every ecm_mp WU is crashing, others are ok:

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.
