40th VI-HPS Tuning Workshop @ LRZ
by Weinberg, Volker May 27, 2021

May 27, 2021

Dear HPC users of LRZ, As member of VI-HPS, the Virtual Institute - High Productivity Supercomputing, LRZ is happy to host the 40th VI-HPS Tuning Workshop on 14 - 18 June 2021, 09:00 - 18:00 CEST. 12 experts will assist you to optimise your code using the tools in the VI-HPS programming tools suite. Please register for free via https://events.prace-ri.eu/event/1207/. The online workshop organised by VI-HPS and LRZ as a PRACE training event will: - give an overview of the VI-HPS programming tools suite, - explain the functionality of individual tools, and how to use them effectively, - offer hands-on experience and expert assistance using the tools. On completion you will be familiar with common performance analysis and diagnosis techniques and how they can be employed in practice (on a range of HPC systems). Those who prepared their own application test cases will have been coached in the tuning of their measurement and analysis, and provided optimisation suggestions. Presentations and hands-on sessions are planned on the following topics: - Setting up, welcome and introduction - mpiP lightweight MPI profiling - TAU performance system - MAQAO performance analysis & optimisation - Score-P instrumentation and measurement - Scalasca automated trace analysis - Paraver/Extrae/Dimemas trace analysis and performance prediction - Extra-P automated performance modeling - [k]cachegrind cache utilisation analysis ... and potentially others to be added The workshop will be held in English and run from 09:00 to not later than 18:00 each day, with breaks. Participants are encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.

Software-Update an den WLAN-Komponenten
by Bernhard Schmidt May 12, 2021

May 12, 2021

Sehr geehrte Damen und Herren, aufgrund einer gestern veröffentlichten Sicherheitslücke in nahezu allen WLAN-Implementierungen müssen die durch das LRZ betriebenen WLAN-Accesspoints zeitnah eine neue Software erhalten. Wir werden diese Aktivitäten in den nächsten Tagen jeweils ab etwa 18 Uhr beginnen. Alle Accesspoints fallen gestaffelt mindestens einmal für etwa fünf Minuten aus. Eine Gesamtdauer oder genauere Zeitpunkte sind nicht absehbar, da der Ablauf durch die WLAN-Controller selbst gesteuert wird.
