Performance Analysis Workshop

Wednesday 24th - Friday 26th April 2019 at University of Bristol

Goals

This workshop is organised by VI-HPS for the UK PRACE Advanced Training Centre to:

  • 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 on the following topics:

  • FORGE/MAP+PR profiling and performance reports
  • BSC tools for trace analysis and performance prediction
  • Score-P instrumentation and measurement
  • Scalasca automated trace analysis

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 17:00 each day, with breaks for lunch and refreshments. There is no fee for participation, however, participants are responsible for their own travel and accommodation.

Classroom capacity is limited, therefore priority will be given to applicants with MPI, OpenMP and hybrid OpenMP+MPI parallel codes already running on the workshop computer systems, and those bringing codes from similar systems to work on. Attendees will need to bring their own notebook computers (with SSH and X11 configured) and use (eduroam) wifi to connect to the workshop computer systems.

Outline

The workshop introduces tools that provide a practical basis for portable performance analysis of parallel application execution, covering both profiling and tracing. It will be delivered as a series of presentations with associated hands-on practical exercises using the ARM-based Isambard Cray XC50 computer.

While analysis of provided example codes will be used to guide the class through the relevant steps and familiarise with usage of the tools, coaching will also be available to assist participants to analyse their own parallel application codes and may suggest opportunities for improving their execution performance and scalability.

Scalasca default module change

The module for Scalasca 2.3.1 (the default module) will be updated on Tuesday 26 February 2019 from cube 4.3.4 and scorep 2.0.2 to cube 4.3.5 and scorep 3.1. You can recover the old behaviour with

module load scalasca
module switch cube/4.3.4
module switch scorep/2.0.2

Container Technologies in Cloud and High Performance Computing - 28-29 March 2019

Not an ARCHER event, but likely to be of interest to ARCHER users.

On 28-29 March 2019 there will be a meeting on Container Technologies in Cloud and High Performance Computing Research and Commercial Applications. This is being organised and run by SURFsara in Amsterdam as part of the CompBioMed project.

It will include speakers from Oracle, EGI and Singularity, along with a number of CompBioMed partners who have been working in this area. The aim is to gather together computational services developers and users from academia, industry and healthcare sectors to discuss the most recent advances in container technology, cybersecurity and related services. It will focus on the use of these technologies in computational modelling and their integration within HPC and cloud computing infrastructures. It is not intended to be focused purely on issues associated with CompBioMed.
