MPI Examples
Intro
I needed to learn myself some MPI, and I thought I could share my learnings in the form of examples. They start being pretty basic, and they become increasingly complex. They are well commented and explained.
Building
In order to build all the examples, just use make. If you want just one of
them, use make XX-super_potato. Each example code is called
XX-super_potato.c, and the compiled executable file once you build it will be
called XX-super_potato.
If you want to delete all the executable files, just run make clean.
Remember: You need to have a MPI implementation, such as Open MPI, installed.
Running
mpirun -np 4 XX-super_potato
This will run the XX-super_potato example, using 4 processes. If you have a
list of hosts you can connect using SSH, you can add the option --hostnames <list>, where <list> is a file with the hostnames you want to connect to,
one on each line.
