RCDC User Guide

Welcome to the RCDC User Guide. We operate multiple compute resources. Sabine is the latest addition. Opuntia is RCDC's most used compute cluster, and Maxwell is still around.

The pages below explain how to access and use the RCDC high-performance computing environment.

If you seek additional help or information not contained in these pages, please open a support ticket.

Technical terms used in the User Guide.

To make the User Guide more accessible, we have tried to explain key terms in a non-technical way. When reading the User Guide pages, please keep in mind the following:

  • a   core  is the microprocessor that carries out the computation (also, "central processing unit", or CPU),
  • a   node  is a machine that will handle your computing tasks (it has memory, cores and an operating system),
  • a   partition  is a collection of nodes with similar technical specifications (amount of memory,   etc.), and
  • the   cluster  is the complete collection of nodes with networking and file storage facilities.
