In the article "Preparing for the Arrival of Intel's Discrete High-Performance GPUs" published on HPCwire, Hartwig Anzt, head of the Helmholtz junior research group FiNE, presents first experiences in software porting for Intel's new Xe GPUs.
Hartwig Anzt 's team is one of the first worldwide to develop software for the expected discrete Intel High-performance GPUs. In close collaboration with Intel and Argonne National Lab, which is planning the first exascale supercomputer based on these GPUs, the research team has developed a backend for the open-source software library Ginkgo in the programming language DPC++, which is already capable of executing numerical methods entirely on Intel GPUs.
The obove mentioned HPCwire article discusses a workflow to convert CUDA code to DPC++ code and the challenges involved. Even though Intel's GPUs and the oneAPI ecosystem are still struggling with various teething problems, the open source strategy Intel has chosen could succeed in bringing the scientific community along.
