Abstract
COLA is a software library for lattice QCD, written in a combination of modern Fortran and C/C++. Intel and NVIDIA have dominated the HPC domain in the years leading up to the exascale era, but the status quo has changed with the arrival of Frontier and other AMD-based systems in the supercomputing Top 500. Setonix is a next generation HPE Cray EX system hosted at the Pawsey Supercomputing Centre in Perth, Australia. Setonix features AMD EPYC CPUs and AMD Instinct GPUs. This report describes some of my experiences in evolving COLA to adapt to the current hardware landscape.
