This workshop organized by VI-HPS, LRZ and IT4Innovations for the PRACE Advanced Training Centre (PATC) at LRZ 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
To foster the Czech-German collaboration in high performance computing, a contingent of places has been reserved for participants from the Czech Republic.
The detailed program will be available on the VI-HPS training web site.
Presentations and hands-on sessions are planned on the following topics (tbc.)
- Setting up, welcome and introduction
- Score-P instrumentation and measurement
- Scalasca automated trace analysis
- Vampir interactive trace analysis
- Periscope/PTF automated performance analysis and optimisation
- Extra-P automated performance modeling
- Paraver/Extrae/Dimemas trace analysis and performance prediction
- [k]cachegrind cache utilisation analysis
- MAQAO performance analysis & optimisation
- MUST runtime error detection for MPI
- ARCHER runtime error detection for OpenMP
- MAP+PR profiling and performance reports
A brief overview of the capabilities of these and associated tools is provided in the VI-HPS Tools Guide.
The workshop will be held in English and run from 09:00 to not later than 18:00 each day, with breaks for lunch and refreshments. The course is free of charge as the workshop is sponsored through the PRACE PATC program. All participants are responsible for their own travel and accommodation.
Participants are encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.
A social event for participant and instructor networking is planned for the evening on Tuesday 24 April, consisting of a guided tour of the Weihenstephan Brewery followed by a self-paid dinner at the brewery restaurant (tbc).

The Intel Knights Landing (KNL) based Next-Generation Many-Core Cluster "CoolMUC3" to be installed at LRZ, soon, will be used for the workshop.
See LRZ announcement. The system is part of the Linux cluster at LRZ, see https://www.lrz.de/services/compute/linux-cluster/overview/.
Course accounts will be provided during the workshop to participants without existing accounts. Other systems where up-to-date versions of the tools are installed can also be used when preferred, though support may be limited and participants are expected to already possess user accounts on non-local systems. Regardless of whichever systems they intend to use, participants should be familiar with the relevant procedures for compiling and running their parallel applications (via batch queues where appropriate).
Location, Transport and Accommodation
The workshop will be held in Leibniz Rechenzentrum on the university campus outside Garching bei München, approximately 25 min north from the city centre of Munich. The U-bahn line U6 (station: Garching-Forschungszentrum) provides direct connection from the campus area to both Munich and Garching.
