Now I got WU for the new app. My old app_config.xml didn´t work, because of the changed application name.

This one works:

<app_config>
<app>
<name>milkyway</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.05</cpu_usage>
</gpu_versions>
</app>
<app>
<name>milkyway_separation__modified_fit</name>
<max_concurrent>2</max_concurrent>
<gpu_versions>
<gpu_usage>1.0</gpu_usage>
<cpu_usage>0.05</cpu_usage>
</gpu_versions>
</app>
</app_config>

If you don't ask how will you know the answer, remember from your school days when the teacher said 'the question you are NOT is the same question the rest of the class is not asking either'! It never hurts to ask, just don't always expect an answer. I used to talk to people who were way above me in the chain of command, I ALWAYS told them, 'just because I ask, doesn't mean you have to answer'! So keep on asking, one day YOU will the one answering the questions!!

What version BOINC client are you using? What applications do you have selected for the project to send?
