Intel Developer Workshop
Contents
This workshop introduces participants to Intel’s modern HPC software ecosystem, with a focus on practical development and performance optimisation using the oneAPI toolchain.
On the first day, the workshop provides an overview of the Intel oneAPI software stack and the Intel LLVM compilers (ICX/IFX). The second day focuses on libraries such as oneMKL and on performance analysis using tools like VTune, APS, and Intel Advisor.
The workshop will provide guidance for the transition from the legacy compilers ICC/IFORT to ICX/IFX.
The program combines lectures with several hands-on sessions.
This workshop is co-organised by the Leibniz Supercomputing Centre (LRZ) and Intel for the German National Competence Centre for High-Performance Computing SIDE.
