ive been running mw seperation wu on my gpus. i saw this post and was hoping to get n-body simulations working for cpu as well. i took that app_info.xml example and modified with the files i have locally for those wu. this is my app_info.xml:

<app_info>
<app>
<name>milkyway</name>

</file_ref>
</app_version>
</app_info>

the gpu still works fine but i all the n-body wu fail on this host

heres one error as an example:

<core_client_version>7.0.25</core_client_version>
<![CDATA[
<message>
- exit code -1073741515 (0xc0000135)
</message>
]]>

for this task.

i got a total of 46 errors for n-body wu. they die immediately so i stopped work for those and will continue crunching gpu on that machine until i can figure this out.

can anyone tell me what may be wrong here? any information would be appreciated.

thanks.

Been a while since I was running nbody, but I think I remember you need to change

<file_ref>
<file_name>libgomp_64-1_nbody_0.84.dll</file_name>
</file_ref>
<file_ref>
<file_name>pthreadGC2_64_nbody_0.84.dll</file_name>
</file_ref>

<file_ref>
<file_name>libgomp_64-1_nbody_0.84.dll</file_name>
<open_name>libgomp_64-1.dll</open_name>
</file_ref>
<file_ref>
<file_name>pthreadGC2_64_nbody_0.84.dll</file_name>
<open_name>pthreadGC2_64.dll</open_name>
</file_ref>

This opens the dlls under their std name and you don't have to rename them in your directory (and do it again with every new version).
