title: How I can use IBM Platform MPI with CUDA?
body: <p>First of all, sorry if I make spelling mistakes, I'm not english.</p>
  
  <p>I'm trying to use IBM Platform MPI v9.1.2 with CUDA 5.5 in Windows 7 to pass messages through GPUs, using CUDA-Aware MPI like this post says: <a href="http://devblogs.nvidia.com/parallelforall/introduction-cuda-aware-mpi/" rel="nofollow">http://devblogs.nvidia.com/parallelforall/introduction-cuda-aware-mpi/</a></p>
  
  <p>My GPUs (Nvidia Tesla C2075) are compatible with UVA (Unified Virtual Addressing) technology, so it should work properly when I use MPI_Ssend and MPI_Recv passing the device pointers, but it doesn't and the program crashes. </p>
  
  <p>I've installed only the IBM package but I couldn't find anything about any configuration needed.</p>
  
  <p>Anyone know something about this and could help me? </p>
  
  <p>Thank you so much.</p>
