Due to the complexity of par- allel programming there is a need for tools supporting the development process. There are many situations where incorrect usage of MPI by the application programmer can automatically be detected. Examples are the introduction of irreproducibility, deadlocks and incorrect ...

Because this is an MPI code where each process will use its own GPU, we need to add some utility code to ensure that happens. ThesetDeviceroutine first determines which node the process is on (via a call tohostid) and then gathers the hostids from all other processes. It then determine...
The work presented in this paper extends an application-level checkpointing framework to proactively migrate message passing interface (MPI) processes when impending failures are notified, without having to restart the entire application. The main features of the proposed solution are: low overhead in...

In this program, we assume that each MPI process is also an NVSHMEM PE, where each process has both an MPI rank and an NVSHMEM rank. #include <cuda.h> #include <nvshmem.h> #include <nvshmemx.h> #include <mpi.h> int main(int argc, char *argv[]) { int rank, ndevices; nvshmem...
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 (...
It adds an additional MPI process for all tasks that cannot be handled within the context of a single MPI process, like deadlock detection. Information between the MPI processes and this additional debug process are transferred using MPI. Another possible approach is to use a thread instead of ...
