Abstract
We present HiRep v2, an open-source software suite for high-performance lattice field theory simulations with dynamical Wilson fermions in higher representations of SU(Ng) gauge groups. This new version fully supports graphics processing unit (GPU) acceleration, optimizing both gauge configuration generation and measurements for NVIDIA and AMD GPUs. HiRep v2 integrates improved gauge and fermionic lattice actions, advanced inverters, and Monte Carlo algorithms, including the (Rational) Hybrid Monte Carlo ((R)HMC) with Hasenbusch acceleration. It exhibits excellent scalability across multiple GPUs and nodes with minimal efficiency loss, making it a robust tool for large-scale simulations in physics beyond the Standard Model.

Funding
This project has received funding from the European Union's Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant agreement №813942. Testing, development, and benchmarking of this software was possible using resources on LUMI-G provided by the Danish eInfrastructure Consortium under grant application number DeiC-SDU-N5-2024055 and NVIDIA V100, A100, and H100 nodes provided by the UCloud DeiC Interactive HPC system managed by the eScience Center at the University of Southern Denmark. This work used the DiRAC Extreme Scaling service (Tursa) at the University of Edinburgh, managed by the Edinburgh Parallel Computing Centre on behalf of the STFC DiRAC HPC Facility (https://www.dirac.ac.uk). The DiRAC service at Edinburgh was funded by BEIS, UKRI and STFC capital funding and STFC operations grants. DiRAC is part of the UKRI Digital Research Infrastructure. Some of the work was carried out using the computational facilities of the High Performance Computing Centre at the University of Plymouth. The authors acknowledge the financial support by the University of Graz.
