Advanced HPC Workshop

22 Nov 2022, 08:50 → 24 Nov 2022, 17:00 Europe/Berlin

online via zoom

Klaus Reuter (MPCDF), Markus Rampp (MPCDF), Sebastian Ohlmann (MPCDF), Tilman Dannert (MPCDF)

Annual workshop of the MPCDF for teaching advanced HPC topics. Mainly

• Debugging HPC codes
• Profiling HPC codes
• Porting codes to GPUs

The workshop focuses on "classical" HPC codes, written in a compiled language (C/C++/Fortran). Hence Python codes are not topic in this event, nor are any AI/ML related codes.
