IIRC O3 caused a lot of coilwhine on my system last time, very annoying so I've been staying away from that one.

Hello, Peter,

Out curiosity I tried 3 All Skys on an rtx 3080 ti since the tasks use so little GPU ram. And often don't use the GPU fully.  After a few seconds the tasks started computation error-ing out. :(   Oh well.

Tried a WU of O3 on win10p.

A single WU is close to 3,9GB in size on GPU ram and the GPU activity is very jumpy. In the time it is mostly flatlining the GPU, doing very little to nothing maybe sitting on a CPU core while holding almost 4GB of GPU ram the whole time. In the beginning it first takes a few 100 MB, then it slowly grows in a few minutes to 3,9GB. Takes around 40min for 1 WU, can't take 2 or more with 8GB. That's around 36 WU of O3 per day @ 5,000 credits a piece. No coilwhine this time, but I'm out of O3.

Now I'm going to try some CUDA testapp on OpenSUSE.

enabled test/beta and ran

enabled test/beta and ran some linux cuda (BRP7-cuda102)

same settings again as in previous posts, here's some quick averages:

1  WU ~535s / 240 W

2  WU ~507s / 247 W

4  WU ~505s / 247 W

10 WU ~501s / 247 W  (IceWM only takes 82 MB gpu ram)

 

edit: around 4% faster for 3% more power

Could someone please help

Could someone please help with updating my app config file to run these MeerKAT work units? I've currently got...

 

<app_config>
    <app>
        <name>hsgamma_FGRPB1G</name>
        <gpu_versions>
            <gpu_usage>0.33</gpu_usage>
            <cpu_usage>0.2</cpu_usage>
        </gpu_versions>
    </app>
</app_config>

 

I'm hopeless at this stuff sorry. 

I'm assuming that I'm only receiving 1 wu is because the script? is wrong?

You have 250 waiting to run.  So you are receiving fine.   I think what you were asking for is how to run multiple brp7/MeerKat's on one gpu?

All you really need is the name of the executable.  I believe it is "einsteinbinary_BRP7".  So your app_config.xml file would look like this.

<app_config>
    <app>
        <name>einsteinbinary_BRP7</name>
        <gpu_versions>
            <gpu_usage>0.33</gpu_usage>
            <cpu_usage>0.2</cpu_usage>
        </gpu_versions>
    </app>
</app_config>

I recommend that you increase your cpu_usage to 0.9 or whatever it is currently using for a single task.  On Linux the fastest processing appears to be a single task per gpu.  YMMV.

HTH,

This solution has the added advantage of allowing you to switch between either task by simply changing what task(s) want to make available on the website.  Or run a mix of both tasks.

FYI, the event log will tell you the correct name to enter here if you don't know the correct format: <name>hsgamma_FGRPB1G</name>.

An example here from my PC. This particular client has an app_config for FGRPB1G but has only seen BRP7 so it is 'unknown'. If you were to enter in the wrong name and you have the tasks, the log will give the correct name.

Your app_config.xml file refers to an unknown application 'hsgamma_FGRPB1G'.  Known applications: 'einsteinbinary_BRP7'

Thank you very much Tom &

Thank you very much Tom & MMONNIN!

That worked perfectly! and yes.... I just wanted to try more than 1 task at a time. 

I've been away from Einstein lately due to high electricity prices (and with summer coming I'll likely be away even longer due to high temps/air con) Is this Meerkat the new work is it? 

Looks like a lot of concurrent wu's being run. 

I see it also looks like the old Radeon VII is far from being king of Einstein any more. Now that Milkyway has ended, I might as well flog them off by the looks.
