1) Message boards : Number crunching : I cant get GPU job for this project (Message 66441)
Posted 14 May 2017 by iwajabitw
Milkyway's GPU requirements are posted here. https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3188#57810

Your card is listed as supported but it could just be a driver issue. Sometimes I have to upgrade or downgrade a driver to get a Boinc project to work.



This is a clip from the posted link:

Milkyway@Home requires a GPU supporting Double Precision arithmetic and OpenCL 1.0.

- Most new cards (year 2012+) should work. If they don't it's a bug, as some driver versions are broken. Many of the broken versions have workarounds.

NVIDIA:
- Requires Compute Capability 1.3 and Above.
- For the GeForce 2xx series, this is the GTX 260 and above.
- Any Fermi based (GeForce GTX 4xx or 5xx) should support doubles.
- Any older GPUs (such as a GeForce 8xxx or 9xxx) will not work[/url]

If your GTX285 isn't too old to run the project. Don't know that card so I cant say. Biggest thing I see is no OpenCL driver listed, may need to update the drivers.

Hey iwajabitw,

The Nvidia and AMD binaries are actually the same. We use OpenCL for our GPU code which is cross platform. Regardless, I see it saying its trying to run the AMD card. The errors are simply due to updating the parameter files. This means runs started before 1.46 use parameter files that are incompatible with the new application. These errors are completely normal and expected. All of the new runs with the new parameter files seem to be running just fine.

Thanks for the update,
Jake

Thanks Jake

I don't know if this means anything, but many of my compute errors like the ones listed in this thread say Nvida in the work unit details. This is a dual R9 280x system.

I would also suggest turning off CPU tasks for MW if you want to run other CPU projects while MW runs on the GPU as stated ealier. Not much bang for buck using the CPU for MW when you are using the GPU.

How about going to the CSG projects preference s page on there website and selecting to only use 75% of the processors' resources, that way it doesn't expect 100% cpu from boinc. Worth a try without an app_config, but I am unfamiliar with that project.

You probably have a bunch cached on your computer. In Boinc Advanced View, press the Show all tasks, instead of Show Active Tasks. You will then probably see them all, highlight and abort them or let them finish. Selecting No new tasks, will just stop the downloads from the server, but continue to crunch what's cached. Suspend the project, will stop it completely.
8) Message boards : Number crunching : Run Multiple WU's on Your GPU (Message 65467)
Posted 18 Oct 2016 by iwajabitw
So after some testing there is no real benefit to running multiple WU on the GTX980. With a max setting in the config file for 20 wu, it takes 12 minutes to process avg, all the tasks. 1 wu setting, takes 40seconds avg. Power % of the GPU never exceeds 58 even at 20 tasks at once. So simple math, I can do 20wu in 12 minutes or 1 in 40 seconds yielding 30 tasks avg complete over the same 12 minutes.

Also with this system AMD A8 APU with Radeon HD 7640G, newest drivers for Win 10. No idea what's up.

Having the same issue on this system. Have not found a way to stop the Computation Error.

How about an a Gtx 980 OC. How many GPU tasks should I be able to run and what what would be the proper edit. On SETI I usually have 3 going to use 99% of the GPU cuda. Thanks.
