Message 64771 - Posted: 29 Jun 2016, 16:05:52 UTC

It's a while ago when i crunched Milkyway as a main project. I left when more than 20% of the wu's failed and the computer hang due to driver resets.
I checked it out now and found a stable project on duty. But i am completely out with the setup to run more than one wu at a time. GPU-workload is at ~97% and ok, but the gap between the wu's is far too long compared to the runtimes.
So my question: has anyone a setup at hands how to run 2 wu's simultanously?

Thanks in advance!

I have been running 2 units at a time on my hd6950.
I use an app_config.xml file in the folder.
\ProgramData\BOINC\projects\milkyway.cs.rpi.edu_milkyway


Contents of file for the MilkyWay@Home application is:

<app_config>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.5</cpu_usage>
</gpu_versions>
</app>
</app_config>

Thanks, works for the MW@Home1.36, but does not work for the Modified Fit.
Which changes are required?
