$HEADER$
ring is a common example of an MPI program; it runs with any number of
processes, and sends a simple message sequentially through all the
processes, with the last process returning the message back to process
zero. This message repeats the "ring" N times.
This example is taken directly from the MPI 2 C++ package
distribution; it is a simple C++ implementation of the standard "ring"
example program. It uses the C++ MPI bindings to effect message
passing.
Use "make" to compile this example. Make will use mpiCC to compile
the program:
mpiCC -o ring ring.cc
This program can be run with any number of MPI processes. For
example:
mpirun C ring
