# HPC examples

A growing collection of ready-to-run examples on the HPC cluster RUDENS. Each repository
has its own README with the exact commands to clone, build and submit.

Prerequisite: an active *RTU HPC (RUDENS)* allocation
(see [Request HPC resource](https://hpc-platforma.rtu.lv/hpc.html#request-hpc-resource-allocation))
and a working cluster connection
(see [Connect to the HPC cluster](https://hpc-platforma.rtu.lv/hpc.html#connect-to-the-hpc-cluster)).

## Examples for educational purposes
