    Hi Folks,

     

    I´ve got a little problem getting E@H GPU tasks to run properly.

    If I run Rosetta@Home on the CPUs and want E@H to be running on the GPUs, it happens that Rosetta takes all CPU slots and E@H is idle due to no available CPU slot.

     

    How can I fix this?

     

    I tried app_config.xml with:

     

    <app>
            <name>einstein_O2MDF</name>
            <max_concurrent>32</max_concurrent>
            <gpu_versions>
                <gpu_usage>0.5</gpu_usage>
                <cpu_usage>0.1</cpu_usage>
            </gpu_versions>
        </app>

     

    Does anyone know how to properly do it (keep E@H priority above other projects which might otherwise take up the needed CPU slot) ?

      I think Einstein tasks require more of the cpu than that, mine take 0.9 percent of a cpu core so until you give it a whole cpu core they won't run.

        Limit Rosetta to 31 (assuming you have a 32 thread machine).

        Create an app_config for Rosetta with a <project_max_concurrent>31</project_max_concurrent> in it. You don’t have to specify the apps. It will be limited to 31 threads leaving one free for Einstein.
