Not sure if you were aware of this, but with render nodes you can run OpenCL programs without X. render nodes requires a 3.12.x or newer kernel and booting with drm.rnodes=1. Prior to render nodes, you could also run OpenCL programs without X, but were limited to one program at a time. -Tom > Al Dorrington > Software Engineer Sr > Lockheed Martin, Mission Systems and Training > _______________________________________________ > mesa-dev mailing list > mesa-dev@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/mesa-dev _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
