NettetMPI is the standard for programming distributed-memory scalable systems. The NVIDIA HPC SDK includes a CUDA-aware MPI library based on Open MPI with support for GPUDirect™ so you can send and receive GPU buffers directly using remote direct memory access (RDMA), including buffers allocated in CUDA Unified Memory. fiber healthy dietNettet3. jul. 2012 · mpicc is just a wrapper around certain set of compilers. Most implementations have their mpicc wrappers understand a special option like -showme (Open MPI) or -show (Open MPI, MPICH and derivates) that gives the full list of options that the wrapper passes on to the backend compiler. fiber healthy snacksWe do ship a pre-built OpenMPI that does have CUDA Aware MPI enabled. So you might try it, at least to see to confirm that's the issue.
