mpirun -np NUM_OF_PROCS ./a.out
| Code | Description |
|---|---|
| helloworld | The most basic program which prints "Hello world" from all the processes |
| hello_send_recv | Illustrates the use of MPI_Send and MPI_Recv functions. The main process sends a message, “Hello, world”, to the process whose rank is 1, and after receiving the message, the process prints the message along with its rank |
