Poem new GPU app update

[zombie67]

Finished two tasks (at a time) on my TITAN. Took 8400 seconds each. 6500 credits each. That works out to ~133k/day.

Running 6 at a time on the TITAN:

Task run time = 15,500 seconds. That works out to ~218k/day. So 6 is better than 2. I will drop it to see what 4 does.

One of the two in the machine is factory OC at 1050. It did a pair in 7700 seconds each, or 146k/day. The other card is slightly OC by me at 975, and did the pair in 8300 seconds, or 135k/day.

(machines with dual 7970s)

The stock machine returned nothing but errors running 3.

The other machine ran 3 at a time in 12,100 seconds. That translates to 139k/day. No advantage to more than two at a time on 7970s, it seems.

Ran a single Poem OpenCL work unit on a 5850, results are not promising for that card: 16,531 seconds for a possible 34,000/day. I'll run one more to confirm, but it doesn't seem like a good use of GPU time. It also appears Poem is suffering from the same issue as before: limited GPU work.

Try running two at a time, just to be sure. Also, BOINC Project Updater is the tool I used for POEM, to make sure I always had work.

Thanks, I'll look into the Project Updater. I'll do some more testing on Poem next week when I get the 7950 I ordered and get to a good milestone on GPUGrid. I'm also hoping they get whatever is causing errors worked out over the next week or two.

Ran a single successful Poem work unit on the 7790, completed in 9690 seconds for a potential 80k/day+.

I removed and reinstalled Poem in a Win7, x64, AMD A8-3870k, XFX 7790 system with app_config set to 1 CPU for every 0.5 GPU. 1 WU ran for 8600 seconds, reported and errored out.

Running 4 at a time on the TITAN:

Task run time = 10,500 seconds. That works out to ~214k/day. So 4 is better the same as 6, and no added value running more than 4. I will drop it to see what 3 does.

I wonder if maybe this project requires DP? Has anyone gotten a SP-only card to return valid results? All my cards are DP, so I can't tell.

Hey I have an A8-3870k/7790 system too! I've errored a few and completed a couple. I'm backing off for now until the project team gets the erroring under control.

Now this is odd!

Running 3 at a time on the TITAN:

Task run time = 6,900 seconds. That works out to ~243k/day. So 3 is better than 4. But how is 3 faster per task than 2???. I think I may have run that 2-per set with CPU tasks also running. I think I will try re-sunning 2-per w/o CPU tasks, to get apples to apples comparison.
