Core A7 switched from AVX back to SSE2

Postby _r2w_ben » Sat Oct 12, 2019 3:50 am

I noticed sse2 mentioned in the startup of the most recent a7 work unit on a machine that supports AVX. I searched through the logs folder and the client switched from using AVX to SSE2 between July 1st and 2nd. Were there assignment or work server code changes that would have affected CPU detection and instructed the client to use SSE2? Anyone that is currently running a7 work units, could you check your logs to see what SIMD method is in use and indicate whether your CPU supports AVX, AVX2, or AVX-512?

Log entries for work unit startups are below.

Re: Core A7 switched from AVX back to SSE2

Postby X-Wing » Sat Oct 12, 2019 3:25 pm

My A7 core is running SSE2, and my Core i3-8350K supports AVX and AVX-2.
Rig: i3-8350K, GTX 1660Ti, GTX 750Ti, 16GB DRR4-3000MHz.

What version of the client are you running, and are your running in a VM?

@_r2w_ben You are running a beta version of the client:
Code: Select all

19:18:29:        Version: 7.5.0
19:18:29:           Date: May 9 2018

Any reason for that? I don't recall the bugs, but there were some with that version and the release version, 7.5.1, was created to fix those.

I didn't encounter any of the bugs fixed in 7.5.1 so I hadn't upgraded. I was minutes away from completing an a7 so I set it to Finish and installed 7.5.1. The new a7 work unit post-upgrade is using SSE2.

Re: Core A7 switched from AVX back to SSE2

There's a log from an AMD Ryzen 2700X that supports AVX2 here that is using the SSE2 version of the core.

This should be fixed now. It was a configuration problem on the AS. Thanks for pointing this out.

My client wants to update core now, but is unable to:

It doesn't really say much in the log, I bumped Verbosity up to 5 to see if that adds any more details... Anyhow, my client is now stuck bumping its head on a wall, it doesn't want to fold anything right now...

Don't bump the verbosity. That just confuses the log.

Pause all CPU slots that are using FAHCore_a7. Now unpause ONE of them and let the core finish downloading. Then unpause the other slots.

How many slots are you running and how many CPUs are assigned to each one?

Having this problem with Core_a7.fah on 2 machines at present (both with 10 cores) all being used for 1 folding slot.
Tried pausing and restarting with no good results.
Deleted cpu and let it fold without for a couple of minutes and then reentered cpu to fold and got this same problem.

I have just one CPU/one folding slot using CPU.

Anyhow, the issue fixed itself overnight! Whee! So thanks to whomever worked some magic to straighten out the problem. Now my CPU folds with AVX(2?) and gets at least 50% higher PPD than before. I'm not sure how much more yet because AVX multiplier was set too low, so all cores clocked down to 3.6GHz... Now they're back at 4.1, but the previously slower speed might still be affecting the score average, I dunno. I will see for sure come next WU in about 10 mins.

Would be cool to see if I could get AVX512 WUs too - as I have an i9 7900X - and see what score I could get with those. Currently I'm peaking at over 180k with 16 threads folding (I want to reserve some of the chip for myself as this is also my personal workstation.)

Cheers and thanks. :)

GROMACS added support for AVX and the release notes commented that there was really very little difference between basic AVX and AVX2. I'm not sure about AVX512 or other vector processing instruction enhancements. In theory, they probably do, but a lot depends on the size of your CPU's cache and how the instructions move data to/from main RAM.
