mpicc

Open MPI C wrapper compiler. The wrappers are simply thin shells on top of a C compiler, they add the relevant compiler and linker flags to the command line that are necessary to compile/link Open MPI programs, and then invoke the underlying C compiler to actually perform the command.

• Compile a source code file into an object file:

mpicc -c {{path/to/file.c}}

• Link an object file and make an executable:

mpicc -o {{executable}} {{path/to/object_file.o}}

• Compile and link source code in a single command:

mpicc -o {{executable}} {{path/to/file.c}}
