This is a set of MPI examples. Listed below are the basic examples, which should be read through and attempted first. There are advanced examples covering more difficult—and perhaps less common—topics.
- example1: "Hello, world" code for MPI.
- example2: First, point-to-point, message passing examples. An example of some deadlocking (blocking
MPI_Recv) code is included. - example3: Numerical integration examples, which highlight choice of cohort size.
- example4: Examples contrasting blocking and non-blocking function calls.
- example5: Communication pattern skeletons, including an example halo exchange.
- example6: Collective communication.
