    Hello,

    I've got two NVIDEA GPU's and Einstein is using them both. But I want to configure boinc/einstein to use only GPU number 1 and not number 0. So only one GPU will be used for crunching. Does anybody know how I can configure that in the cc_config file (or somwhere else)?

    Regards,

    Jos

      Yes, you can do that. It's described in the Client configuration page of the User manual.

      <exclude_gpu>
         <url>project_URL</url>
         [<device_num>N</device_num>]
         [<type>NVIDIA|ATI|intel_gpu</type>]
         [<app>appname</app>]
      </exclude_gpu>

        Hi Richard,

        Yes I've seen that. But I want only to use GPU 0 for all applications in Boinc. Is that possible?

          That's not what you said the first time - you said you wanted Einstein to use GPU 1. And you didn't mention excluding other projects, too.

          But never mind. That's in the same page of the user manual:

          <ignore_nvidia_dev>N</ignore_nvidia_dev>
