It can be easily compiled by doing `mpicc bench.cpp -o bench` and then submitted to the scheduler. /* skip C++ Binding for mpich , intel MPI */ #define MPICH_SKIP_MPICXX /* skip C++ Binding for SGI MPI library */ #define MPI_NO_CPPBIND /* skip C++ Binding for OpenMPI */ #define OMPI_SKIP_MPICXX #include <mpi.h> #include <stdio.h> int main(int argc, char *argv[]){ int rank; int world_si…
