Hi James:
I can reproduce the problem on a single node with Open MPI 1.5 and the
trunk. I have submitted a ticket with
the information.

Hi,
I'm getting strange behavior using datatypes in a one-sided
MPI_Accumulate operation.
The attached example performs an accumulate into a patch of a shared
2d matrix. It uses indexed datatypes and can be built with
displacement or absolute indices (hindexed) - both cases fail. I'm
seeing data validation errors, hanging, or other erroneous behavior
under OpenMPI 1.5 on Infiniband. The example works correctly under
the current release of MVAPICH on IB and under MPICH on shared memory.
Any help would be greatly appreciated.
Best,
~Jim.
