Restricting maxwell core18

Given some known driver issues with recent NVIDIA maxwell chips and Core18 (https://www.reddit.com/r/foldingathome/ ... l_support/), we are temporarily restricting our core18 projects (e.g. 1047*) to use pre-maxwell GPUs. I'll be making the changes Friday morning. Hopefully this restriction will be a temporary fix, with full maxwell support in the future.

Hopefully we have enough 9201 to crunch and it take not much time for nV to deploy a revised version ...

Oh, and happy new year 2015 :D

Does this mean that the "workaround" code for the NV bug will be removed from Core_18?

Thus (hopefully) making it easier to produce a Linux version which will be ready to go when nVidia get their act together :wink:

For now, the core version will stay the same. Eventually we hope that the workaround will no longer be necessary.

Not seen any changes yet on a couple of GTX 970's - did P91xx's get included in this restriction?

Happy New Year everyone and thanks to Kyle for getting me up to speed on whats been happening. I have restricted 9104-9114 Core 18 projects to be pre-Maxwell as well. Cheers!

Excellent - Well I think that is a positive start to GPU Folding in 2015.
We now just need to finish off the rest of the (EOL) Core 15 WU's .... :D

Maybe ... maybe not. WUs should be assigned based on both availability and on priority. If there are currently no high-priority WUs available for whatever reason, does it make more sense to assign a low-priority WU or to give a message saying no WUs are available? As long as there's still important scientific value in collecting more low-priority data, then shouldn't it be happening?

Of course there are a lot of unknowns about the future. Once FAH's Streaming Infrastructure is rolled out, almost anything can happen but I think it's fair to assume the current infrastructure will remain in place, at least for a long time.

Well, that's an awesome start to the new year!

Thank you for stepping up in support of us Maxwell purchasers - especially those who've purchased them solely to contribute to FAH.

I do not know that that is a fair statement, The problem is a NVidia driver issue not a F@H issue I do not think PG can do anything about it in this case.

I understand that it is a driver issue but the fact that PG made a move like this is encouraging to me for all users.

As one who has purchased a GTX980 strictly for folding, I am extremely pleased at this adjustment. The last 19 workunits I've received for my 980 averaged 36,000 and 39,000 every two and a half hours, consistently over 300,000 points per day with a very fast turnover.

The first week I had my 980 it was producing at the same rate but then the new workunits arrived and production plummeted to the point that I almost quit folding entirely. I bought the GTX980, a GTX760, and a GTX770 all during the two months prior to the disaster.

Since I am retired living on Social Security and a very small pension those three video cards were a MAJOR investment for me and I was really offended by the points decrease by those workunits on the 980.

And i by 3 more 980, i will then have 11 980 and 5 970. 100% 24/7 FAH.
