You can then run the program by typing . If you want to specify the name of the output file, you can use the -o flag, as follows:  g++ prog.cpp -o prog This will produce an executable file called For programs designed to run in parallel, you might include libraries such as for shared-memory parallelism or for parallelism. To compile a parallel program using OpenMP, you would use the -fopenmp flag and run the executable just like a serial program. For MPI-based programs, you compile using a specialized compiler wrapper, such as , and run the program across multiple processes using the command.
