DCSR Software Stack
What is it?
The DCSR provides a software environment including commonly used scientific tools and libraries.
The software is optimised to make best use of the CPUs, GPUs and high speed Infiniband interconnect.
In order to create the environment we use the Spack package manager and Lmod.
For information on the deprecated Vital-IT software stack please see here.
Release and lifecycle
Each year we provide a new release of the software stack which fixes versions for key tools and libraries - the new stack is put in production during the annual maintenance in early January and the previous release remains available for one year.
