The purpose of this document is to serve as a simple introductory guide to the use of the University of Canterbury's IBM High Performance Computing (HPC) facility (otherwise known as BlueFern). A general schematic of the system is presented as well as information on how to perform the following tasks:

  • Login to the AIX environment
  • Login to the Linux environment
  • Change your password on the system
  • Navigate around the key file systems
  • Use of the compilers
  • How to run serial and parallel executables
  • How to use the job scheduling system
