Remove the Max_Concurrent lines as you do not need them for that system.

Do you feel it was coincidental that two GPU WUs started as soon as I ran that configuration? The 960 had been running for roughly 10 hours with only a single WU on the GPU, and immediately after I read that configuration file I saw two WUs in progress. Although, I also saw only a single CPU WU processing. It's completed a number of GPU units at this point, and it's still running two of them.

Can someone point me a guide to app_config syntax, if such a thing exists? I've looked, and can't find it.

Google "app_config.xml" (without the quotes). The first item you get is the BOINC Wiki page on the subject ("Client Configuration"). Then scroll down to the section on Application Configuration.

Or just click application configuration

Thanks! This is exactly what I was looking for.


Using this ...
<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>.25</gpu_usage>
<cpu_usage>.2</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.5</gpu_usage>
<cpu_usage>0.4</cpu_usage>
</gpu_versions>
</app>

</app_config>

... I get 8 CPU WUs and 4 GPU WUs running. I had an astropulse unit running before I read the above, and it dropped out afterward. I guess I've still got some studying to do.

I don't yet understand the useage values fully.

... I get 8 CPU WUs and 4 GPU WUs running.

I'd keep an eye on the run times; as power full as the GTX 960 is, I suspect 2 at a time (maybe 3) would be the optimum number for WUs processed per hour. Running as many as 4 will most likely result in less work done per hour than just running 2 at a time.

As Grant says, while a gtx960 might run 4MB at a time it will be far, far more productive running two or three, so:

<app_config>
<app>
<name>setiathome_v7</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.2</cpu_usage>
</gpu_versions>
</app>

will be more productive.
Once you've got a feeling for two at a time, over a couple of weeks at least, increase to three at a time <gpu_usage>.33</gpu_usage> and let tht settle for a couple of weeks.

If you want to see the sort of figure you should be getting from your system with a GTX960 running take a look at the figures for my computers, in particular 7047761 which has a RAC of about 20,000 from a GTX760 and being fed by a six core Phenom.

gpu_usage 0.5 say use .5 of GPU
so no more than 2 tasks can run if they can't get more than 0.5 to start up

0.3 should get you 3 tasks running, a third of 100 percent .. there is not enough left for the 4th task to start

cpu_usage is a strange dog and looking at it may seem like a bad Idea, but good in the long run. Try shutting down a CPU.

Try 0.6 CPU and 0.5 your gonna get a free core to feed the GPU.

If your GPU out preforms your CPU you could see a big difference.

Thanks for all the feedback. And, thanks Brent for the explanation. That clears things up.

I'll leave things as is for a while. I'm monitoring closely for the time being. Presently, my RAC is rising by the hour. When it has leveled out I will fiddle a bit as suggested in the above posts and see what the effect is. I'll establish a baseline for comparison before doing so.

I really appreciate all of the advice.

Nine days after installing the 960, the RAC for this PC is up from 2,171 to 7,482. So, a RAC increase of 5,311 attributable to the 960 alone.

RAC is still climbing though, at a rate of more than 400/day. Sitting tight with settings until I see a leveling.

I've also observed that I can remove some programs from my exclusion list, as there is no longer a problem crunching while running them.

A footnote to this thread:

Changing from a GeForce GT 610 to the 960 on March 19th. It was 20 days before the server problems messed up my smooth line of RAC increase. At the time I had nearly reached a RAC plateau.

Best I can figure, there was an increase to my RAC (on this computer) of about 8,400 attributable to the GPU upgrade alone.

Now I've added a couple more projects, that would further complicate figuring out the difference. So I'm happy with doing 5X as much crunching on this computer, and glad the outage didn't happen sooner than it did.

Thanks again for all of the help and suggestions. I'll probably seek the collective expertize again in the future. :-)
