For OpenMPI v.1.1 and later use OMPI_CXX and then call the wrapper compiler. The wrapper would call clang++ in turn. Unfortunately, this does not seem to work if you need to use multiple "wrapper" compilers, e.g. nvcc + mpicc.Installing from source requires compilers and a working MPI implementation. The mpicc compiler wrapper is looked for on the executable search path (PATH environment variable). Alternatively, you can set the MPICC environment variable to the full path or command corresponding to the MPI-aware C compiler.Jan 8, 2022 · To compile the code we use mpicc: mpicc main.c -o main.o. To run the executable we use mpirun. The argument -np 4 indicates the number of processors on which the above code will run in parallel: mpirun -np 4 main.o. Both commands ( mpicc and mpirun) became available when we install the Open MPI using brew.
