Just received Server responded WORK_QUIT (404) / Server did not like results, dumping .. there goes several days of GPU work

The GPU is EVGA Nvidia GT 710 2GB, no overclocking.

I suspect it may have something to do with CORE_OUTDATED received in the middle of uploading the results:

No. The CORE_OUTDATED event had nothing to do with the server's rejection of the WU.

You're talking about project:16434 run:232 clone:3 gen:13 which was also identified as WU02:FS01. It was rejected by the Collection Server.

Perhaps it had expired You would have to look back in the previous logs to find when that WU was assigned and downloaded.

I happen to have personal experience with a GT710 which is a very slow GPU. It is very difficult to complete assignments before they expire.

Posted: **Fri May 15, 2020 4:33 am**

The WU was definitely completed before the deadline; I've been watching it very carefully.

ETA: Yes, I realize that the core was updated when the next WU started; I was wondering if core restarting in the middle of the completed unit submission had some effect on the submission itself.

When a WU is not returned quickly, duplicates are issued. Assuming your result was error-free, it should still have been accepted, even if a duplicate was completed before you uploaded your result. I'll have to check to see if that happened.

According to the public records, Two people returned it (not counting you). One had an error and the other completed it successfully.

Your WU as rejected at 02:23:39 ... presumably that on 2020-05-15
2020-05-15T02:23:39

Posted: **Fri May 15, 2020 5:16 am**

The successful WU as issued at 2020-05-09T06:28:32 and returned at 2020-05-09T18:18:46 and was credited at 2020-05-09T18:25:42
Your WU as rejected at 2020-05-15T02:23:39
Unfortunately I can't tell when your WU was assigned to you. Can you find that date/time?

Like you said earlier, GT 710 is a slow card by today's standards, but I was watching the progress very closely and the unit finished about 20 hours ahead of the expiration deadline (taking into account that the times are in UTC). It usually doesn't cut it *that* close, but indeed struggles to complete units before the "timeout".

This is an old Linux box that I had resurrected to fold, with the idea of it sitting quietly in a corner and not being used for anything else other than looking for a possible cure. Based on the above, even if my client returns complete WUs, it is likely that someone else has already finished the same WU. I'll have to rethink whether it's a rational use of electricity, as much as I would like to help.

I'm sure this question has been asked before .. will go do some soul-googling with the morning coffee.

A lot of COVID19 projects run on the CPU so you can still contribute. Removing the GPU slot would let the CPU slot use both cores.

Posted: **Wed Jun 17, 2020 9:04 pm**

I have a veriety of GPUs, including one GT710. (It's the only GPU that will fit in that slot.) FAH is doing some WU/GPU optimization studies and they are distributing some small proteins to slow GPUs. (They haven't said anything about the proposed deadlines, though.) I hope they do manage to send my GT710 WUs where it can do some good and avoid burdening it with big WU where it can't help.) I'll be very happy to have the GPU idle a lot of the time, just displaying my desktop the rest of the time.

Posted: **Fri Jun 19, 2020 7:24 pm**

Oh no! I'm so sorry this happened.

> I was wondering if core restarting in the middle of the completed unit submission had some effect on the submission itself.

I don't think this should impact things.

We're about to roll out a bunch of COVID Moonshot projects that work well for older GPUs and run in just a few hours. Hopefully this will help---we very much value these contributions!

Revisiting the old subject, in case someone runs into this thread...not sure if the new (smaller) projects have been released, or if the new '13' core with support for CUDA is making a difference, but now my old GT710 is cranking through WUs in 3 hours or less, well before the timeout deadline.

Posted: **Tue Sep 29, 2020 11:53 pm**

The CUDA optimizations on Nvidia GPUs does provide a decent speed-up from anywhere of ~15% to 100% depending on the simulation type. Traditional simulations are towards the ~15% improvement while the free energy calculations (primarily use in Moonshot Projects) are towards the 100% range.
