I'm particularly interested in the performance / responsiveness tradeoff on mid-low range GPUs. Many thanks to cncguru for donating his GTX 480. If I hadn't had it, it would be about 30% slower than it is. http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48_x86_64-pc-linux-gnu__cuda_opencl.tar.gz http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48_windows_intelx86__cuda_opencl.zip Extract these to the project directory. On Windows this is something like C:\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway On Ubuntu for me, this is /var/lib/boinc-client/projects/milkyway.cs.rpi.edu_milkyway Minor update: http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48.1_windows_intelx86__cuda_opencl.zip http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48.1_x86_64-pc-linux-gnu__cuda_opencl.tar.gz Another minor update: http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48.2_windows_intelx86__cuda_opencl.zip http://milkyway.cs.rpi.edu/milkyway/download/test/milkyway_separation_0.48.2_x86_64-pc-linux-gnu__cuda_opencl.tar.gz ID: 44588 · Rating: 0 · rate: / Reply Quote

You have to manually download from the links I posted. I'm not putting it up as stock yet. I think the server still needs to be updated for that to happen, and I want to hear if the system responsiveness is a problem on some lower end GPUs. ID: 44591 · Rating: 0 · rate: / Reply Quote

I've got 195.30 and cuda 2.3 The minimum driver which is supposed to work is 197.13, but I've only actually tested with the latest drivers. ID: 44613 · Rating: 0 · rate: / Reply Quote

But NP, I'll try latest drivers... ID: 44615 · Rating: 0 · rate: / Reply Quote

Is anyone running it in a system with both ATI and Nvidia drivers installed? I just realized a hypothetical problem that might happen. ID: 44617 · Rating: 0 · rate: / Reply Quote

The latest driver (260.19.21) is on CUDA 3.2, so I think it's necessary to get cudatoolkit 3.2 from here ID: 44618 · Rating: 0 · rate: / Reply Quote

If I remember correctly, you will need at least a 26x.00 driver to use the openCL app. Upgrading the driver did the trick, you were right on this. I had a version beneath 260.x. Thanx for that hint! The WUs are running fine now. :-) Member of BOINC@Heidelberg and ATA! My BOINCstats ID: 44620 · Rating: 0 · rate: / Reply Quote
