4) Message boards : Number crunching : ATI GPU not getting any work (Message 1854388) Posted 10 Mar 2017 by Jason A. Countryman Post: Sorry to bring up an older thread, but it looks like there has been some new AP work, and this cruncher decided to grab some for the ATI card. All of them quickly errd out. Might be a good idea to mask the open source ATI drivers for AP as well. Has anyone had any luck getting these cards to crunch with the MESA driver yet? Another issue, I decided to add a second project to this host with a low resource share just to keep it fed when there is no work here. Sometimes it will crunch enough of those so that it wont at least let SETI crunch 2 concurrent GPU applications (1 core per GPU app) while it uses the CPU. I added an app_config file to it, limiting that project to 6 concurrent threads, but is there a better way to prioritize the GPU apps so that if it runs out of SETI GPU work it will then let the other project have all the cores?

5) Message boards : Number crunching : ATI GPU not getting any work (Message 1839260) Posted 31 Dec 2016 by Jason A. Countryman Post: Oh man, thanks for the info. It's mint 18 so based on ubuntu 16.04. I tried to get catalyst installed, but it really wasn't happening. Might be time to replace that card with a second NVIDIA and save the headaches of managing both.

6) Message boards : Number crunching : ATI GPU not getting any work (Message 1839254) Posted 31 Dec 2016 by Jason A. Countryman Post: Ah, good catch. Unfortunately those are mostly CPU tasks that failed to download. Probably started BOINC too soon, had a bunch of reboots to get both GPUs working correctly.

7) Message boards : Number crunching : ATI GPU not getting any work (Message 1839250) Posted 31 Dec 2016 by Jason A. Countryman Post: Just checked, both applications are selected. Yeah I do have a lot more of the GUPPIs in my task list right now, but I believe that both GPUs crunched those as well before the OS reinstall. Everything was fine up to last week when I set it to no new work in preparation for a clean OS install.

8) Message boards : Number crunching : ATI GPU not getting any work (Message 1839244) Posted 31 Dec 2016 by Jason A. Countryman Post: Hello all, I recently upgraded one of my hosts and it seems that SETI@home no longer wants to use my ATI GPU. BOINC sees the card and has been requesting work for it, but not getting anything. The NVIDIA card is crunching away however. From the log: Sat 31 Dec 2016 12:07:34 AM EST | | OpenCL: AMD/ATI GPU 0: AMD CYPRESS (DRM 2.43.0, LLVM 3.8.0) (driver version 11.2.0, device version OpenCL 1.1 MESA 11.2.0, 1024MB, 1024MB available, 522 GFLOPS peak) Any ideas?

9) Message boards : Number crunching : RAC for host seems low (Message 1837262) Posted 22 Dec 2016 by Jason A. Countryman Post: Actually it wasn't too bad. I used the repository drivers for the ATI, then when I added the NVIDIA, I used their drivers. The only issue I ran into was after the second driver install, it wouldn't start X windows. I just had to copy the backed up xorg.conf file back to the one used. I don't think this would work if I wanted to run a display off the 580, but its only for crunching.

10) Message boards : Number crunching : RAC for host seems low (Message 1837246) Posted 21 Dec 2016 by Jason A. Countryman Post: Hi Bob, I actually already have it set to only use 4 cores when the GPUs are in use. I set my cc_config file to use 1 CPU per GPU WU. With this I usually see around 83-84% utilization on the CPU with some spikes up to around 90%. Maybe I need to go up to 5 free cores and see if that helps? Its hard to be sure since the NVIDIA tools don't show me the actual GPU utilization for the 580.

11) Message boards : Number crunching : RAC for host seems low (Message 1837215) Posted 21 Dec 2016 by Jason A. Countryman Post: Hi everyone, I've had one of my crunchers up and running for a bit now and it seems like its RAC is lower then it should be. It has an ATI 5850 and an NVIDIA GTX 580 both doing 2 WUs at once, as well as 4 out of 8 cores crunching. 5850 is usually 90-97% utilized and is also driving the monitor. 580 wont show its utilization, but is usually at least 70C with its fan spooling up to 40-60%. Last I had heard the stock apps for GPUs were best, so everything is stock at the moment. One thing I did notice is that its BOINC version is a bit far behind at 7.2.42. Seems I got stuck with Linux Mint 17.3 KDE as I can't upgrade to the newer versions without a fresh install and 7.2.42 is the latest BOINC version in its repos. Host is: http://setiathome.berkeley.edu/show_host_detail.php?hostid=7738389 if your curious.

13) Message boards : Number crunching : Concurrent GPU tasks (Message 1759491) Posted 26 Jan 2016 by Jason A. Countryman Post: So I tried setting the CPUs to .75, and my utilization went down to the 80% range. I then set it to 1, and I'm back to 94-95%. Im wondering if its worth loosing another core to get to 97% or best to leave it where it is.

14) Message boards : Number crunching : Concurrent GPU tasks (Message 1759264) Posted 25 Jan 2016 by Jason A. Countryman Post: So I changed it to .5 GPU and 1.5 CPU in app_config. I am now running at 96-97% GPU utilization, with 5 of 8 cores also running tasks. Im not sure if I should give it more CPU cores or go back to 3 tasks. Update: I tried going back to 3 GPU tasks, and giving each task 2 cores. The GPU utilization would drop into 80% sometimes, then go back to 98-99%. I went back to 2 tasks with 1.5 cores for each. That seems relatively stable at 96-97%.

15) Message boards : Number crunching : Concurrent GPU tasks (Message 1759260) Posted 25 Jan 2016 by Jason A. Countryman Post: Thanks for the info, I will try the CUDA app for the Mac. I have been checking on the GPU utilization using the aticonfig commands on the linux box. It was around 90-94% utilization with one task, and 97-99% when running 3 tasks. If it stays that high with only 2 tasks, should I leave it at 2? I don't mind the screen lag as this is primarily a web/media server and I don't use it directly very often.

16) Message boards : Number crunching : Concurrent GPU tasks (Message 1759244) Posted 25 Jan 2016 by Jason A. Countryman Post: Hello all, I am in the process of setting up a new app_config file for v8 and plan on running stock apps for a bit to get a benchmark. I know there was a post linking a tool to determine the best number of concurrent tasks for each GPU, but I can't seem to find it. I am running linux with an FX-8300 processor and a Radeon 5850 GPU. Right now I am running 3 GPU tasks at once, with each task getting .75 of a core. Any suggestions? Thank you.

Countryman Post: Hi all, I would like to run the optimized CPU app on my MacBook, but as there are no NVIDIA OS X optimized apps for SETI or AP, run the stock AP GPU app. Is this just asking for trouble? Would I be better off running the optimized CPU app and not use the GPU for now? Thank you
