Milkyway help

[aux9o]

I just installed a quad core processor a few weeks ago into my milkyway rig. I noticed that every since i am not doing as much wu's as i used to. I was getting over 300,000 per day now im down to maybe 200,000 per day. I noticed that it is taking over 45 sec to do one wu. I can suspend my cpu task and the amount of time drops to 27sec per wu. But I would like to be able to run a cpu project while getting the best out of my gpu on milkyway. What can I do to fix this?

Sounds like you need to reserve a CPU core for Milkyway. In BM set "Use all CPUs" to 75%.

Edit: The above is for non-HT CPUs. For CPUs w/ HT use 87.5%

You could also use a app_config file to reserve an entire thread to feed your GPU on MW. I've actually ended up going this route on several GPU projects I've crunched recently.

Can you help with setting this up?

Drop this into the MW project folder and name it "app_config.xml" (without the quotes). Then hit "read config files" in the BOINC manager. It is setup to run 2 WUs at a time, and each will reserve half a CPU (so, two WUs reserves a whole CPU thread). Should work. If not, let us know how it goes.

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

Don't forget to mention that "app_config.xml" does require a relatively new BOINC Client. It was added in the 7.0.40 release.

This looks like it is working. Maybe better then before!

Glad to hear it! Keep us posted...

If this is your rig with an HD 7970, I would change the gpu_usage to .25 - I have found that 4 work units yields best results on faster cards. Milkyway has pretty low CPU overhead so you can change cpu_usage to .05 or match your gpu_usage to keep a core dedicated.

I got a Dell t7400 with a 6900 series and I also installed the 7970 in there. I have one card running 4 wu's at a time but only 1 card is running wu's. What have I forgot to do to make both cards run?
