Project 16417 fails on high core count machines

Postby Area256 » Mon Apr 06, 2020 11:45 pm

I'm having a problem with Project 16417 (and possibly similar ones) on very high core count machines (128 threads in this case).

I think the issue is having too many threads assigned to the core. If I limit the number of threads then the unit will run. Also frustratingly when it fails it just keeps retrying instead of reporting the failure and trying to get another unit, so my system stays idle constantly retrying until I limit the number of cores for this unit by switching to "Light" folding power.

Re: Project 16417 fails on high core count machines

There are a limited number of CPU projects that will run on that many threads, the rest usually have upper limits set for assignment.

What was the size you were able to run this project on? I will pass this information back to the researcher so they can check and adjust the limits for this project.

I was able to run it on 64 threads (which seems to be the limit set by the "Light") option. I'm afraid I didn't test anything higher.

Other settings would need to be made through FAHControl's Configure. But that at least gives some useful limits.

Thanks for flagging! I've updated the project thread limits so that it only uses 64 cores and below since that was the limit you tested.

FYI - A larger core count might have been the reason my Project: 16417 (Run 2023, Clone 4, Gen 2) failed on a 24core slot .. it has since been successfully completed by someone else - so upper limit might be less than 64 ??

Further update from another thread … https://foldingforum.org/viewtopic.php?f=19&t=34072#p323443 might have to go as low as 8cores for this?

Ignore me … Joe_H has responded on other thread … given the 64 core that worked he reckons probably multiple of 5 is the issue … not sure about my 24core failure but happy for that to be an anomaly.

Initializing Domain Decomposition on 48 ranks
Dynamic load balancing: auto
Will sort the charge groups at every domain (re)decomposition
Initial maximum inter charge-group distances:
    two-body bonded interactions: 0.429 nm, LJ-14, atoms 4153 4162
  multi-body bonded interactions: 0.429 nm, Proper Dih., atoms 4153 4162
Minimum cell size due to bonded interactions: 0.472 nm
Maximum distance for 7 constraints, at 120 deg. angles, all-trans: 1.138 nm
Estimated maximum distance required for P-LINCS: 1.138 nm
This distance will limit the DD cell size, you can override this with -rcon
Guess for relative PME load: 0.17
Will use 40 particle-particle and 8 PME only ranks
This is a guess, check the performance at the end of the log file
Using 8 separate PME ranks, as guessed by mdrun
Scaling the initial minimum size with 1/0.8 (option -dds) = 1.25
Optimizing the DD grid for 40 cells with a minimum initial size of 1.423 nm
The maximum allowed number of cells is: X 4 Y 4 Z 4

By turning FAH down to medium so it only runs on 47 threads, it runs fine:

You may find setting core count to 32 will complete the WU.

However, if the WU was downloaded at a setting of 24 for the CPU thread count you will not be able to raise it over that number.

Sorry, was responding to Zzyzx post which had log showing was running 48 then 47 threads … and I guess there may be a number between 32 and 47/48 that works as well … My bad.

Please note that in the current client, there's no argument value called "bigbeta" so you can remove it.

Yeah, I was getting the error with 48 threads. I found by turning it down to 47 (which actually decayed down to 45 because of primes,) it ran just fine.

Project: 16417 (Run 904, Clone 3, Gen 243) Decomposition Fail. I thought this would not get assigned to 48 thread machines after all this conversation, but I got one this morning. Changed to 45 threads per _r2w_ben advice and processing fine. Just passing FYI.
