WALDUR: Access the HPC Platform

The heart of the National Open HPC platform is WALDUR, a user-friendly self-service portal for requesting and managing access to computing resources.

The built-in Marketplace offers a catalog of HPC services provided by Latvian academic institutions (currently RTU and LU), including:

  • Virtual desktops

  • HPC clusters

  • Jupyter notebook environments

How to get invited:

  • Research groups, course instructors, or individual students working on research or thesis projects should contact the RTU HPC center.
