2024-06-10 VI-HPS Tuning Workshop (hhps1s24)

Contents

This on-site workshop organised by VI-HPS and 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

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 optimisation suggestions.

Programme Overview

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
• CUBE profile processing and exploration
• Scalasca automated trace analysis
• Paraver/Extrae/Dimemas trace analysis and performance prediction
• Linaro MAP profiling and performance reports
• Extra-P automated performance modeling
• [k]cachegrind cache utilisation analysis
• ... 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.

The workshop will be held in English and run from 09:00 CEST to not later than 18:00 CEST each day, with breaks for lunch and refreshments.

Participants are encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis.

Programme in Detail (provisional)

all times given as CEST (UTC+2)

Hardware and Software Platforms

CooLMUC2: Haswell-based x86 Linux cluster system:

• 28-way Haswell-based compute nodes and FDR14 Infiniband interconnect, used for both serial and parallel processing

The local HPC system CooLMUC2 is the primary platform for the workshop and will be used for the hands-on exercises. 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).
