High-Level GPU Programming (CSC-Vienna Scientific Cluster-EuroCC collaboration)

14.2.2024 09:00 +02:00 EET - 16.2.2024 17:00 +02:00 EET

CSC Training Facilities

Modern HPC systems combine CPUs and accelerators such as GPUs or FPGAs, making code optimization for diverse platforms time-consuming. Cross-platform portability ecosystems provide a higher-level abstraction layer, simplifying parallel programming in shared memory environments. Examples include SYCL and Kokkos for C++. SYCL, an open standard by Khronos Group, offers a unified C++ layer for diverse devices, achieving parallel execution on CPUs, GPUs, FPGAs, and more. Kokkos Core, a C++ framework, enables high-performance applications across HPC platforms, addressing challenges of intricate node architectures. Kokkos supports various backend programming models like CUDA, HIP, SYCL, HPX, OpenMP, and C++ threads.

This training organized by  CSC in collaboration with VSC / EuroCC Austria introduces GPU programming using SYCL and Kokkos to write portable and performant accelerated applications. The course consists of lectures and hands-on sessions using LUMI, Mahti, and Intel DevCloud, featuring AMD, Nvidia, and Intel GPUs, respectively. At the end of the training, we also provide opportunity for the participants to apply the acquired knowledge to personal coding projects and real-world application scenarios.

Learning outcomes:

At the end of this training, participants will be able to:

  • write hardware-agnostic code to express parallelism using SYCL and Kokkos that can run on CPUs and GPUs 
  • manage memory across devices
  • do basic performance analysis 
  • evaluate the drawbacks between different approches for programming GPUs


Prerequisites and content level:

This course targets developers who know C++ and would like to learn how to program GPUs or for developers who are already doing GPU programming using a non-portable approach such like CUDA or HIP and would like to write performant code which runs on various computing platforms. In order to be able to follow the course the participants are expected to have basic familiarity with C++ concepts such as raw pointers, classes, structures, templates, lambdas, functors.

The content level of the course is broken down as: beginner's - 70%, intermediate - 20%, advanced - 10%, community-targeted content - 0%.
