ENCCS AMD GPU Hackathon'23 test cases

This repository contains small test cases (<5 min runtime) for the ENCCS AMD GPU hackathon.

Code

We will use the develop branch of Neko from the main repository: https://github.com/ExtremeFLOW/neko

Developer documentation for Neko is available at: https://extremeflow.github.io/neko

Instructions

Each case provides its instructions but relies on a HIP installation of Neko. To build Neko, please follow the general build instructions given in the Neko README to generate the configure scripts (regen.sh). Then follow the general HIP instructions (ExtremeFLOW/neko#585), or the LUMI specific instructions (ExtremeFLOW/neko#665) depending on the target system.

Note: It's important to always configure Neko with a given installation prefix:

> ./configure --prefix=/path/to/neko/installation ...additional flags...

otherwise, tools like makeneko or the pkg-config files will not work.
