OpenGL on k10, k20c, k20m (GOM switch)?


Is there any official information available from NVidia about OpenGL support on the Tesla k10 and k20 models? I’ve seen empirical evidence that and thus OpenGL isn’t supported on the k20c. In this thread ( a switch controling the GPU Operation Mode is mentioned that allows to influence what features are available (including enabling/disabling graphics mode). But no information on what GPUs support this switch and which modes? E.g., apparently, the k20c doesn’t support mode switching to graphics.
