So here's my question: can I continue building the application as I normally do then, say, on Windows, start multiple threads with _beginthreadex and, in each of the threads call MPI_Init_thread? In other words, would all subsequent calls to MPI behave as if I had a true ...

As an aside, with the MPI portion of the code the programmer manually decomposes the domain. With OpenMP, the compiler does that automatically if the program is running in a shared memory environment. Currently, OpenMP compilers aren’t able to automatically decompose a problem across multiple dis...
Progress Thread Placement for Overlapping MPI Non-Blocking Collectives using Simultaneous Multi-ThreadingNon-blocking collectives have been proposed so as to allow communications to be overlapped with computation in order to amor-tize the cost of MPI collective operations. To obtain a good overlap ratio...
Using NVSHMEM With MPI or OpenSHMEM NVSHMEM can be used with OpenSHMEM or MPI, which makes it easier for existing OpenSHMEM and MPI applications to be incrementally ported to use NVSHMEM. The following code snippet shows how NVSHMEM can be initialized in an MPI program. In this program, we ...

The above command runs perfect and I am able to seenvidia-cuda-mps-serverand fourgmx_mpiprocesses on GPU 0. However, the issue arises when the job scheduler assigns another job on the same node. Note that nodes have 2 GPUs, therefore it assigns the jobs to the other GPU (...
