Events 2020
VIHPS Tuning Workshop: December 2020
Monday-Friday, Dec 07th - Dec 11th 2020
The workshop will be held in English and run from 09:00 to not later than 18:00 each day, with breaks, all times given as CEST (UTC+1).
Location: Virtual using the Zoom platform.
Goal
This workshop organised by VI-HPS and CSC/HKHLR 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 participants should 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 optimization suggestions.
Program
Presentations and hands-on sessions are planned on the following topics:
Setting up, welcome and introduction
MAQAO performance analysis & optimisation
Score-P instrumentation and measurement
Scalasca automated trace analysis
VAMPIR interactive trace analysis
PAPI hardware performance counters
Extra-P automated performance modeling
… and potentially others to be added
A brief overview of the capabilities of these and associated tools is provided in the VI-HPS Tools Guide.

Tune your own code
Participants from Academia
- are encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.
- who have a piece of their own code that they would like to adapt and speed up using VIHPS tools can send it to the organizers to include it in the course as a case study. Please make sure that it is already runnable on the Goethe-HLR cluster. If you are interested in tuning your code, please send us a short code description at least till Monday, November 23rd (gerbes@csc.uni-frankfurt.de).
- who wants their code to be analyzed has to install their code to the workshop accounts on the Goethe-HLR. The installation will be possible starting on Monday, November 23rd.
Registration
