Getting started…

This tutorial page is dedicated to the usage of Liger Cluster, and should help you to get a better understanding of the machines you are going to use, and provide you with enough elements to run your first jobs. Make sure to fully understand the “My First Steps” section content, in order to be able to follow the walk through in the “Advanced” section.

A note on parallel computing: Newcomers unfamiliar with the basis of parallel computing are invited to consult the excellent LLNL tutorial (below) on the subject, as well as an explanation of the differences between the two main programming methods used in parallel computing: OpenMP & MPI.
