=====Note: Induction Course=====

Please see the CHPC [[https://moodle.chpc.ac.za/course/view.php?id=21|Induction]] course for new users.  

======Practical HPC — CHPC Winter School======

This page collects all the lecture notes, video links and worksheets from the CHPC's Winter School in one place for use by anyone who wants to self-study or teach.

The Practical HPC course is intended to teach practical skills for using the CHPC supercomputer cluster effectively and efficiently.  It cover two main topics:

  - Workflow to Job Script
  - Scaling

over two weeks.  These topics are approximately 6 sections, with a core of 4 sections and 2 optional sections.

=====Prerequisites=====

Students will need to be familiar with both the Linux command line and the concepts of High Performance Computing.

====Supercomputing MOOC====

{{ :workshops:prace_epcc_logo.jpg?200 |}}

This course is presented in conjunction with [[http://www.prace-ri.eu/|PRACE]] and [[https://www.ed.ac.uk/|EPCC]] who provide a free online course on the basic concepts of HPC. This provides the main background knowledge you will need to understand HPC and how the CHPC cluster works. 

  * PRACE **[[https://www.futurelearn.com/courses/supercomputing|Supercomputing]]** MOOC


The first 4 weeks of the PRACE Supercomputing MOOC provide the necessary foundational information and concepts for this Practical HPC course.

You will need to complete all of the first 4 weeks of the Supercomputing MOOC to be fully prepared for all the topics in the CHPC Practical HPC course.

====Linux Shell Command Line====

There are many resources on the Internet that introduce the basic commands of the Linux shell.  We recommend:

  * [[https://swcarpentry.github.io/shell-novice/index.html|The Unix Shell]] --- //Software Carpentry//
  * //Learn Linux// [[https://www.learnlinux.org.za/courses/web-courses|Fundamentals]] course

=====Workflow to Job Script=====

First we cover the basics of the user's view of the cluster and how to write, submit and monitor a job script.

=====Scaling=====

Scaling is the performance of a parallel program across different number of nodes and cores.  First we cover the basics of compiling a program for the cluster, then we look at performance measurement and scaling.

====Compilers and Libraries====

=====Further Reading=====

====Parallel Programming====

We are often asked about porting or writing programs to parallel hardware.  This is a large and more advanced topic and so we can point you to some resources that can help you start.
