[OMPI users] cuda-memcheck reports errors for MPI functions after use of cudaSetDevice

Hello everyone, in my application I use CUDA-aware OpenMPI 1.10.2 together with CUDA 7.5. If I call cudaSetDevice() cuda-memcheck reports this error for all subsequent MPI function calls: = CUDA-MEMCHECK = Program hit CUDA_ERROR_INVALID_VALUE (error 1) due to "invalid argument"
