GPU CORE22 0.0.2 coming to ADVANCED

Postby rafwiewiora » Fri Jan 03, 2020 8:28 pm

The updated GPU Core 22 is here! This is based on OpenMM 7.4.1 - we're starting with the OpenCL version first. Stability has drastically improved from 0.0.1 -- I'm seeing 0.3% failure rate in BETA.

The deadline and credit were adjusted to increase the PPDs by the performance speedup / increase in science produced (speedup is ~20% on 1080/1080Ti benchmark machine). Please watch out for temperature and wattage increases, and consider reducing OC.

Project stats:

11737 (DHFR benchmark)
core: Core22 0.0.2
# atoms: 23558
credit: 7498
k-factor: 0.75
timeout: 5.8d
deadline: 8.2d
precision: mixed

It will take another day or two before I make it active -- this is an advance notice -- and I will go in small batches of letting a few hundred WUs out and then switching off ADVANCED for a bit and so on -- so that if there's problems they'll be contained to a small amount of donors, and if you have failures other projects will be downloaded instead.

Thank you all!

Since no one can post in this announcement thread, I opened a feedback one here : viewtopic.php?f=74&t=32073

I'm releasing the first batch of WUs.

Nearly 150 WUs were released to advanced, stopping for now until I see results of those.

6% failure rate in the first batch -- not great, not too bad -- (cf. core21 failure rate on full F@h is ~5%) -- I call this good enough to start a second batch of about 500 WUs - distributing now. Very interestingly, 8/9 failures seen in the first batch were due to the same error - `clWaitForEvents`, and I'm investigating further.

Currently seeing only a 3% failure rate in the second batch, so I'm leaving the ADVANCED flag on constantly now.
