Hello, The Error is not 100% reproducible for me every time but seems to disappear entirely if one excludes -mca osc ^rdma or -mca btl ^openib component.
The error is present in 2.0.0 and also 2.0.1rc1.

I am attaching a test case that works fine with Open MPI 1.8.3 and fail with version 2.0.0 with the following output: === [0] MPI_Get 0 -> 3200 on first memory region [cl3fr1:7342] *** An error occurred in MPI_Get [cl3fr1:7342] *** reported by process [908197889,0] [cl3fr1:7342] *** on win rdma window 3 [cl3fr1:7342] *** MPI_ERR_RMA_RANGE: invalid RMA address range [cl3fr1:7342] *** MPI_ERRORS_ARE_FATAL (processes in this win will now abort, [cl3fr1:7342] *** and potentially your MPI job) === Expected output is: === [0] MPI_Get 0 -> 100 on first memory region: [0] Done. [0] MPI_Get 0 -> 100 on second memory region: [0] Done. === The code allocates a dynamic window and attaches two memory regions to it before accessing both memory regions using MPI_Get. With Open MPI 2.0.0, only access to the both memory regions fails. Access to the first memory region only succeeds if the second memory region is not attached. With Open MPI 1.10.3, all MPI operations succeed. Please let me know if you need any additional information or think that my code example is not standard compliant. Best regards Joseph -- Dipl.-Inf.
