Well, seems I forgot to do some stats yesterday. 😳 So I'll just do the sprint stats this time around.
We do have a chance to gain another point in the PrimeGrid marathon, but beyond that I don't see any immediate gains made there.
So, here are the slightly early sprint stats🙂
We are in second place at the moment. At one point earlier today we were in third, but the gap seems to be widening between us and OcUK🙁 Maybe some of our residual tasks from the recent challenge will be validated and help spur us on to victory😀

Well I awake to find us now in 4th place. OCN added SEVEN GTX 1080's recently (That's about 8M PPD), and this was after they had already became a threat to not only us but OcUK as well.

I'll have to admit, I'm awestruck at the reserves OCN has at it's disposal.
 
Hey, ladies and gents!

I just recently started computing again. It's getting colder outside, so I'm turning work into heat for my living room with my gaming rig. Wee!

Man, League 2's sprint this week is really heating up! This is oddly exciting.

I put my lil' 970's and 5820k to work when I'm not using it on PrimeGrid hoping to help, but I doubt it's going to make much difference against those 7 1080's. Either way, it's an interestingly close sprint and I'm glad to help out with what I can! Maybe we can secure 3rd place at least? We'll see!
 
Thanks for the heads up! I mistakenly had some CPU tasks set for PPS Sieve, and they're...taking forever. Going on 10 hours with ~5 hours to go. I really don't want to just cancel them since they're 60-67% done, but it may not be worth it to let them finish. 🙁
 
On my AMD boxen, I'm trying to put some shorter run-time PPS-Sieve in behind some GFN-21 units that are finishing up. The problem is, that BOINC is suspending the almost completed GFN-21s in favor of starting new PPS-Sieve units instead, which is not the desired behavior. Anyone know how to stop this from happening?
 
Maybe increasing the "Switch between tasks every [...] minutes" to a few thousands helps. Or maybe not.

Due to nuisances like this, I no longer run more than one (sub-)project in a single client.
 
Crash, can you do the weekly stats tomorrow? I 'get' to work tomorrow since I was off today for the company family appreciation day event.
 
So, we have dropped to fourth in the sprint, but the good news is we have gained a spot and a point in the marathon.😀
Looks like we better start digging through our closets and dragging out all those AGP cards and firing them up, who cares about global warming😱
Lets hope tomorrow is a better day.😵

OK, I am very dedicated to F@H for obvious reasons(my cancer), but I could spare a GTX 980. What is the project ? I may need babysitting on instructions if its not so simple as to add a project in the list.
 
Primegrid is the project for this sprint, I would run the GPU sieve sub-project seems to do very well.
I would go with the 980Ti or 1070 since it is only another day or two.
Make sure they are clean, it loads up a GPU pretty good.
 
Well, I added it to the computer that has the 980, and changed the config to say "GPU always", but its not using it, so I turned if off, sorry

At www.primegrid.com, go to "Your account" -> "PrimeGrid preferences" -> scroll down -> "Edit PrimeGrid preferences" -> at the top, switch off "Use CPU", switch on "Use NVIDIA GPU".

Then switch off all applications in the long list below, only switch one on in the "Subproject (Sieve)" section: "Proth Prime Search Sieve (PPS-Sieve)", only enable the CUDA option.

Then scroll further down, click "Update preferences". Then hit Update project in boincmgr.
 
PrimeGrid certainly has far more options than any other project I've seen. I believe that none of the GPU sub-projects are checked by default, so one has to do as Stefan describes to get a GPU crunching.
 
Finally I have realized that running other CPU projects concurrently with PrimeGrid has been killing the performance of my GPUs, no matter the settings used. Not sure why, but I guess all my CPU work is on hold for the next 23 hours or so.
 
Markfw's F@H thread made me follow a routine whenever I run a GPU application: Either I don't run CPU work at all on the same host, or I adjust CPU allocation while monitoring the behavior of the GPU application, and dial back on CPU work if I notice a negative effect.

And I check in task manager that process priority of GPU feeders is higher than that of the CPU work. To this end I have <process_priority_special>2</process_priority_special> in cc_config.xml. See the boinc wiki for explanation. But for boinc applications which ignore this parameter (IIRC the dnetc client which runs inside moowrapper is one of them), and for F@H, I run a powershell script which periodically looks for processes of a given GPU application and adjusts their process priority.

OK, I got it running. 8 minutes a task ?

Great, thanks for joining this team effort.

Thanks for helping out here. As soon as the sprint is over (Monday 05:59 UTC = Sunday 22:59 PDT), my GPUs will be back at F@H.

Edit: countdown to the finish
(UTC) https://www.timeanddate.com/countdown/generic?iso=20171030T0559&p0=1440
(PDT) https://www.timeanddate.com/countdown/generic?iso=20171029T2259&p0=202

8 minutes sounds reasonable. Though on a GPU of the size like the GTX 980, it's possible that the shader cores aren't fully utilized. If GPU-Z or HWinfo64 or some other monitoring tool shows an average GPU utilization significantly less than, say, 85 %, its worth trying to crank performance up with an app_config.xml file.

Thinking out loud a thought which just occurred to me: All Formula Boinc sprints begin shortly before a weekend. If the sprint is on a quorum=2 project like this one, there will systematically be a portion of tasks from sprinters which will not be validated during the sprint: Those who have wingmen who do DC only during workdays.

I feel your pain (Pending 2294) but its the same for all teams. A midweek Sprint would be good.
