One task is performing a send operation and the other task is performing a matching receive operation. There are different types of send and receive routines used for different purposes. For example: Synchronous sendProcess one then allocates a buffer of the proper size and receives the numbers. Running the code will look similar to this. >>> ./run.py probe mpirun -n 2 ./probe 0 sent 93 numbers to 1 1 dynamically received 93 numbers from 0.
