Same with me. A ton waiting to upload, and nothing downloaded.

I had trouble with the N body apps before. Are those no longer being used? I had a very high failure rate on those.

I will wait until the bugs are worked out to hit MW hard again.

I have found my card will run the most work at 2 tasks at a time. It takes 240 seconds to run 2 tasks at once, so 120 per task. If I do one at a time it takes 135 seconds. If I go up the 3 tasks it drops the output to even less than one at a time, so 2 is the sweet spot.

Correct. I don't do the N-Body because they always screw up in some way. Invalid (bay have a bug) or validation inconclusive. Something always seems to go wrong with them.

This is my current app config file-
<name>milkyway_nbody</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_separation__modified_fit</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_nbody</name>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>milkyway_nbody</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>1</avg_ncpus>
<cmdline>--nthreads 1</cmdline>
</app_version>
</app_config>

I could actually pull the N-Body stuff out since I won;t do them anymore.

I would like to set my system up to run certain apps on GPU and others on CPU. Right now I am running the same apps on both. I want to run the Separation apps on CPU only and keep doing the Milky Way apps on GPU only. Is there any way to do that?

I was looking for this as well. My newly modified app_config file is working great.

<app_config>
<app>
<name>milkyway_nbody</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_separation__modified_fit</name>
<gpu_versions>
<gpu_usage>.5</gpu_usage>
<cpu_usage>.5</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_nbody</name>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>milkyway_nbody</app_name>
<plan_class>mt</plan_class>
<avg_ncpus>1</avg_ncpus>
<cmdline>--nthreads 1</cmdline>
</app_version>
</app_config>

Everything else runs on one CPU, N-Body should as well. 7 CPU tasks and 2 GPU tasks at a time keep everything loaded nicely.

So you don't have more than 40 tasks in progress? I just looked and your fastest machine is showing 20 tasks in progress. My fastest machine has 64 right now. (and yours is faster) I wonder if you need to change a setting like under network usage under boinc computing preferences, the "Maintain enough tasks to keep busy for at least". I have it set for .5 days. I think default was .1 days.

I used a combination of Keith's last post and Hal's and figured it out. Thank You.
I have used Cmd very little. I have used Powershell far more, but am no wiz with that either.

Thank you again for your help and patience. I am great at building computers and overclocking CPU's/GPU's, but not that good at this kind of thing yet. I have a lot to learn.

Windows 10. Using the Cmd prompt does nothing with that line.

Where do I do that? Excuse my ignorance, but what command line?

I think I figured it out. Will wait and see how it does. I have an overclocked GPU that has been working at half speed so far. I hope this helps it get more done. I may need to do some more tweaking.

I would think someone has done this before and has an example of the config file. On Seti it is common. Information is easy to find.

How do you set up an app-config file with milky way? I have one for Seti, but am unsure how to do it for MW.Just letting it go how it is set up it uses almost no processor or CPU power. I want it to run at least 2 GPU tasks at a time and another 6 CPU tasks, reserving 2 CPU's for the GPU tasks.
This is my Seti App Config file-

<app_config>
<app>
<name>setiathome_v8</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>1.00</cpu_usage>
</gpu_versions>
</app>

<app>
<name>astropulse_v7</name>
<gpu_versions>
<gpu_usage>0.50</gpu_usage>
<cpu_usage>1.00</cpu_usage>
</gpu_versions>
</app>
</app_config>

I am unsure how to name them for Milkyway.
