would you mind sharing this patch? We'd like to test our current VT version with
some MPI RMA code :)


No problem-o. I've submitted this patch upstream to Intel as well. Note that the patch slightly changed between 3.1 and 3.2; this is the 3.2 patch:

           ierr = MPI_Win_free(&c_info->WIN);
           MPI_ERRHAND(ierr);
        }

Does anyone know of some (small) code/benchmark that uses all available MPI RMA functionality? As far as I see, IMB only uses fence and put/get/ accumulate. No
locks or post/wait/start/complete...


We have a few one-sided tests in the ompi-test repository (which I think Dresden has access to?), but I'm not 100% sure that they're correct...
