In late summer / autumn 2024 HLRS is going to install its next supercomputer system called “Hunter”. As for every new system, users have to spent some effort into porting their code and workflow to the new environment. Furthermore, the vast majority of Hunter’s compute power will be delivered by GPUs, which requires users to adapt their hot loops in order to offload them to the GPUs. In this workshop we will hence support our users in doing both.
As Hunter is going to deploy the Cray Programming Enviroment (CPE) which is available (but not default!) on Hawk as well, it’s possible to do first porting steps already in July on Hawk. This allows to extend the timeframe available for porting. Work done in this workshop can be immediately reused on Hunter.
Those first porting steps will include building with the respective compilers, linking against highly optimized numerical libraries provided by CPE, and using CPE’s performance analysis tools. Based on the latter, the time till arrival of the new system can be used to identify and offload hot loops.
