1. OpenMP offloading in C/C++ and Fortran, i.e. with the help of compiler directives and a supporting compiler, e.g. Intel’s icpx (C/C++ compiler) and ifx (Fortran compiler) which is available in intel/... environment modules.
   Intel provides an OpenMP Offloading Tuning Guide.

2. SYCL for C++, i.e. in a data-parallel and explicit fashion (similar . Similar to CUDA ). Different to OpenMP, SYCL provides for more control over the code, data movements, allocations and so forth that are actually executed on the GPU. The SYCL implementation for Intel GPUs is provided by oneAPI. On the PVC partition, SYCL code can be compiled with the icpx compiler from the intel environment environment module(s). Migration of existing CUDA codes can be assisted using the DPC++ Compatibility Tool. The dpct binary is available via the intel/... environment modules. Note that SYCL codes can also be executed on Nvidia (and AMD) GPUsbut open and cross-platform. See SYCL for more details and code examples.

Please refer to the oneAPI Programming Guide for further details about programming. Contact NHR@ZIB support to get assistance on getting your application run on Intel GPUs
