Oh that's actually not true for the full k20 series. the k20m (server modules) should support switching, the k20c (workstations) might not.
https://devtalk.nvidia.com/default/topic/528048/k20-gpu-operation-mode-support/ https://devtalk.nvidia.com/default/topic/534299/tesla-k20c-or-k20m-/ Probably the K20Xm should still allow to set it to ALL_ON - can you confirm that? Good luck!
