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.

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.

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.

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?

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.

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.

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.

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.

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%.

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.

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.

Cool, thanks for the replies.

I will just leave it as is for now.

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

I am crunching on a 2.0GHZ macbook core duo and i frequently see CPU temps as high as 90 when crunching, and im even using a cooling pad. I have been letting it do this for several months now and havent had any problems, but it is uncomfortable to use it on my lap without the cooling pad while its crunching

I am running mine at around 65 degrees. I think its a little high but not dangerously so.

i have seen a usb to ethernet adapter, not sure if that would work or set one computer to share the wifi connection to its ethernet port, then plug that into a router and connect anything you want

you should be able to get a router, plug its connection for internet into your family's hub, then you can have all the ports you want on your end of your router

If you want linux you can go to ubuntu's website and they will send you the disc for free. That would be a good place to start if you havent used linux before.

non system disc usually just means that there is nothing on the hard drive. No OS, nothing. Just put in an install disc for windoze or linux restart and it should install
