In 2018, the MPG supercomputer Hydra is gradually replaced by the new, much more powerful Cobra system. A second phase will follow in 2019/2020.
This article describes the recent changes to the anonymous FTP server at the MPCDF and also highlights the use of the Datashare service as a preferred solution for future data sharing use cases.
In this article, we describe two lightweight profiling tools, likwid (developed by RRZE) and ftimings (developed by the MPCDF) which facilitate performance analysis and guide node-level optimization. Likwid is a mature and well-known tool suite that is now also supported on MPCDF HPC systems. The ftimings library takes a more minimalistic approach by providing a simple API for instrumenting sections of interest in application codes.
This article presents an introduction to the new WebIDE integrated in GitLab.
