[OMPI users] bug in CUDA support for dual-processor systems?

2012-07-31 Thread Zbigniew Koza
Hi, I wrote a simple program to see if OpenMPI can really handle cuda pointers as promised in the FAQ and how efficiently. The program (see below) breaks if MPI communication is to be performed between two devices that are on the same node but under different IOHs in a dual-processor Intel
