Hello, how can I set up an app_info or app_config file to

a) Receive NBody MT WU's only - no single core
b) Receive NO Milkyway WU's for CPU but only for GPU

Would be nice to have an option in the preference menu.

Thank You

Phil1966

Hello Phil,

because of overheating-problems I wrote the following app_info.xml for my Linux-PC:

<app_info>
<app>
<name>milkyway</name>
<user_friendly_name>MilkyWay@Home</user_friendly_name>
</app>
<app>
<name>milkyway_nbody</name>
<user_friendly_name>MilkyWay@Home N-Body Simulation</user_friendly_name>
</app>
<file_info>
<name>milkyway_1.46_x86_64-pc-linux-gnu__opencl_nvidia_101</name>
<executable/>
</file_info>
<file_info>
<name>milkyway_nbody_1.70_x86_64-pc-linux-gnu__mt</name>
<executable/>
</file_info>
<app_version>
<app_name>milkyway</app_name>
<version_num>146</version_num>

<avg_ncpus>0.841226</avg_ncpus>

<plan_class>mt</plan_class>

</app_info>

You have to modify
- the name of the executables if you are using Windows (or the version changes! In this case run BOINC without an app_info.xml first to download the new files.).
- the "plan_class"/"type" according to your GPU (the correct values can be found in your client_state.xml).
- the values of the "flops" to have right runtime estimations (-> client_state.xml).
- the values of "avg_ncpus" (-> client_state.xml).

I hope this will work on your machine, too!

With greetings

NN
