Organising Institutions

Goals

This workshop, organised by VI-HPS and HPC.NRW, 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.

Programme Overview

Presentations and hands-on sessions are planned on the following topics:

• Score-P instrumentation and measurement
• CUBE profile processing and exploration
• Scalasca automated trace analysis
• Extra-P automated performance modeling
• MAQAO performance analysis & optimisation
• ... and showcase presentations/demonstrations of other tools.

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 17:30 each day, with breaks for lunch and refreshments.

On-site participants are encouraged to prepare their own MPI, OpenMP and hybrid MPI+OpenMP parallel application codes for analysis. Codes using multiple GPUs via OpenACC, OpenCL or CUDA may also be analysed.

Programme in Detail (provisional) - all times given as BST (UTC+1)

Hardware and Software Platforms

HPC Hardware Lab @Durham

The local HPC system HPC Hardware Lab @Durham 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).

Registration

This workshop is on-site and in-person.

Participation is free of charge.

Registration via the registration website.
