Project 17236 - Early Unit End

[satcat16609]

Over the last week, I've noticed a five WUs, so far, failing with an "Early_Unit_End" warning. All five WUs are from Project 17236. Below are the relevant WU entries from HFM.Net. I've also included a snippet from the log file from the PCRG 17236 (265,117,4). The message is the same for all of the WUs.

It's a wild guess, maybe someone can confirm/deny. I think that you run 10 threads (see Calling: mdrun -s frame4.tpr -o frame4.trr -x frame4.xtc -cpt 30 -nt 10). I read somewhere that jobs from older projects sometimes can't really deal with a multiple of 5 cores (nope, didn't understand either). This project is still an a7 core project, and that definitely falls under 'older'. It may be related if you read the explanation of the error: http://www.gromacs.org/Documentation/Er ... ze_of_x_nm

So I'd suggest reducing the number of cores to 8 or 9, and see if the problem persists.

[satcat16609]

I've been using the CPU on Medium power, which sets the system to use ten cores, and this is the first project where I've had any issues. I had read last year when I started folding that there are certain numbers of cores that don't work well, but have always assumed the software would default to using a proper number of cores. Perhaps this particular project doesn't like ten cores. Thanks for the info.

[bruce]

FACore_a8 supposedly fixes this type of error but it's still present in _a7 and older cores. Projects started with older cores will continue to use that core (including follow-in clones of the same study) until the study is finished.

Requesting "large prime' numers of cores (including multiples of primes, like 5 cores) do sometimes fail, but it's somewhat a random faiure. You may have completed some WUs from that project. Setting your slot to 9 cores or 12 cores will probably "solve" the problem for you. The project owner can also exclude assignments to clients which are requesting assignments to clients with 10 cores.

[satcat16609]

Well, I adjusted the cores to 9, and then got back-to-back WUs from Project 17236, and they both completed successfully. Thanks for the info.

[DeeGee]

Yeah, seems like that project didn't like my 5950x that has been set to 28 threads instead of the default 31. Almost no CPU WU's and then the few ones received crashed...

[JimboPalmer]

28 is 7 by 2 by and a7 'hates' large primes like 7, 27 would be 3 by 3 by 3, much smaller primes.
One of the improvements in a8 is coping better with primes.
