Message 44714 - Posted: 15 Oct 2016 | 16:23:20 UTC

Hi all,

I apologize if this has been asked many times before but I am just wondering if it is possible to run 2 projects on my gtx 960. If it is, how may I do so? Is there a way to have them both running and use 100% usage of the GPU?

Thanks!

The file was placed into the gpugrid projects folder?

Did you tell boinc manager to read config files after updating app_config.xml?

I do not see a folder that is dedicated to GPU grid, so I put it in the Boinc folder.

Yes, I also hit for it to read the config files.

Place that file into the <drive>:\ProgramData\BOINC\projects\www.gpugrid.net folder.

None of the folders you pointed to me exist. I created them and still no luck...

Aha!

I've fixed the issue. I had to locate my folder by searching it up. Now I am running 2 tasks at once at around 70% usage. How may I make the boinc manager download a 3rd task? I have changed store at least an additional "1" day. Is that correct?

Thank you all again, couldn't have done it without you.

It's easy to do but not a good idea. The admins want fast WU turnaround. Running 3 WUs at a time will take more than 24hr turnaround and will also cause you to miss the 50% bonus (especially with the long WUs). With more normal long WUs than we have at the moment you'll probably also lose the 50% bonus since you're not running very fast GPUs. You may also run into memory problems since they only have 2GB memory. If you want to try 3x on the short WUs you could try:

<app_config>
<app>
<name>acemdlong</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
<app>
<name>acemdshort</name>
<gpu_versions>
<gpu_usage>0.33</gpu_usage>
<cpu_usage>1</cpu_usage>
</gpu_versions>
</app>
</app_config>

You also should be getting much more than 70% usage even running 1x.

Okay, I will stay with 2 tasks running.

With 1 task I get around 78% I see and with 2 I get around 88% usage. I assume it is like that due to the WDDM.

I might just install Linux alongside windows 10.

I've tried windows XP already and although things went nice, it'll be harder when I get a new gpu because of no new drivers being made for xp. I've tried 7 and 10 but I dislike the wddm.

Message 44752 - Posted: 17 Oct 2016 | 17:40:57 UTC - in response to Message 44747.

Okay so I've tested ubuntu and the usage is only 80%... doesn't ubuntu have no WDDM?

I guess I should state my objective now. Before I wanted to run multiple tasks, but now, I've gotten to the point to where that doesn't matter anymore. All I'd like to do is find an operating system to use with no WDDM. I do not want to stick with windows XP because if I were to get a new GPU, there would be no drivers for it.. Or is XP my best option for now?

I'm just trying to get a stable OS for my machine so I can sit back and let the projects crunch away.

You should set the SWAN_SYNC environmental value under Linux too, to get the maximum possible GPU usage. But you should set it for the user which runs the BOINC manager. I'm not into Linux at all, but I've seen a post about it a couple of months ago.

Logan,

I get better utilization in Ubuntu when I reserve 2 CPU's (2 threads = one physical CPU in a hyper-thread machine) for each GPU task. My utilization is usually 92-95 percent running one task at a time on each GPU. My app_config.xml looks like this:

<app_config>
<app>
<name>acemdlong</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>2</cpu_usage>
</gpu_versions>
</app>
<app>
<name>acemdshort</name>
<gpu_versions>
<gpu_usage>1</gpu_usage>
<cpu_usage>2</cpu_usage>
</gpu_versions>
</app>
</app_config>


Hope that helps.

Thank you, captainjack!

I bookmarked what you typed so I can refer back to it. Much appreciated.

At what nice (priority) does boinc_client run?
Usually boinc runs cpu apps at lower priority than gpu, but if it already runs at lowest this is not possible. Some distributions run it at nice 10 (good) some at 19 (lowest).
Freeing cpu cores does help, but you loose computational power.
Disabling HyperThreading(tm) can help.
You can try to apply realtime priority to acemd process with chrt --rr -pa 2 {pid}, but this is one-time and difficult to automate.
