Parallel Performance Analysis using Scalasca

22 - 23 August 2023 09:30 - 16:30 BST in Oxford

Scalasca is a portable, free and open-source software tool that supports the performance optimisation of parallel programs by measuring and analysing their runtime behaviour. The analysis identifies potential performance bottlenecks – in particular those concerning communication and synchronisation – and offers guidance in exploring their causes. It uses execution profiles and traces generated by the community-developed Score-P instrumentation and measurement infrastructure.

Scalasca targets scientific and engineering applications based on the programming interfaces MPI and OpenMP, including hybrid applications using a combination of the two. The tool has been specifically designed for use on large-scale systems, but is also well suited for small and medium-scale HPC platforms. The software is available for free download under the New BSD open-source license.

This online course will cover how to use the tools in practice, delivered by members of the development team. Scalasca is portable across HPC systems, but for this course practical exercises will be conducted on the UK National HPC Service ARCHER2 (an HPC Cray EX system); all attendees will be given accounts on ARCHER2 for the duration of the course. Although example parallel programs will be provided, attendees are encouraged to analyse the performance of their own applications.

Computational Science Centre for Research Communities (CoSeC) 2023 Conference

Call for Presentations – Deadline 31st October 2023

The Computational Science Centre for Research Communities (CoSeC) invites submissions for its next annual conference, to be held at the Manchester Centre Convention Complex on Wednesday the 6th of December 2023 in conjunction with the Computing Insight UK event.

This is an opportunity for those involved in activities supported by CoSeC (Collaborative Computational Projects, High-End Consortia, and other activities within the UKRI Digital Research Infrastructure landscape) to present cross-cutting aspects of their work to like-minded researchers as well as leading members of the computing industry.

We invite abstract submissions around the following topics:

  • Modelling, Simulation & Reconstruction: All aspects of computational science related to modelling, simulation and reconstruction. It is important that presented work be of interest to those outside of its immediate scientific community, with the most relevant work being that which has potential applications across the sciences.
  • Scientific Reproducibility: Work relating to enabling reproducibility across computational science, from workflows through to ensuring data is produced and stored in accordance with the principles of FAIR (findable, accessible, interoperable, reproducible).
  • Applied Artificial Intelligence and Machine Learning: The use or development of AI or ML data science approaches within the context of computational science. The most relevant work is likely to provide clear application beyond the fundamental and have potential applications across the sciences.
  • Large Scale Computing for Computational Science: All aspects are invited for submission, from applied supercomputing (e.g. developments toward exascale and work related to the use of national infrastructure like ARCHER2) through to topics around accessibility, and usability of computational science methods or software on large scale computing platforms.

Accepted speakers will be able to present their work in Manchester with no associated registration fees as well as gain access to the full CIUK event on the 7th and 8th of December. Upon acceptance an optional extended version of the abstract will be published as part of the main CIUK conference proceedings.
