High Performance Computing: An Introduction
Prerequisites

Wed 10 Jun 2020
CANCELLED

Description

Bookings for this course are placed on hold in response to the rapidly changing events due to COVID-19. The status of these courses will be reviewed towards the end of April 2020. See the University's COVID-19 page for up to date information.

The course aims to give an introductory overview of High Performance Computing (HPC) in general, and of the facilities of the High Performance Computing Service (HPCS) in particular.

Practical examples of using the HPCS clusters will be used throughout, although it is hoped that much of the content will have applicability to systems elsewhere.

Target audience
  • All current Cambridge University members (departments and colleges)
  • Novice users of HPC and anyone who expects to need to use HPC systems at some stage in their research
  • Further details regarding eligibility criteria are available
