Preparing programming models for Exascale

Author: Daniel Holmes
Posted: 18 Jun 2019 | 15:03

To make future heterogeneous systems easier to use efficiently, the EPiGRAM-HS project is improving and extending existing programming models with Exascale potential. We are working with the MPI and GASPI programming models primarily, but also applying our changes to HPC applications like Nek5000, OpenIFS and iPIC3D, and AI frameworks like TensorFlow and Caffe. We expect the trend towards specialisation of hardware will continue and therefore large machines will become more and more heterogeneous.

Too much choice?

When is enough, enough? With so many parallel programming technologies, should we focus on consolidating them?

At the ISC conference in June I will moderate a panel discussion on whether it is time to focus on the consolidation and interoperability of existing parallel programming technologies, rather than the development of new ones.

TeamEPCC will participate in the ISC19 Student Cluster Competition on 17–19 June in Frankfurt, Germany. Please come to visit us at Booth A-1452

TeamEPCC undertook a special two-day training in May provided by our team’s sponsor Boston Ltd to further prepare for the ISC19 Student Cluster Competition (SCC). During the training, the team had plenty of opportunities to assemble the hardware and experiment with multiple system softwares.

Women in HPC (WHPC) was set up in 2013 to tackle the problem of diversity in HPC through research and education. EPCC initiated the WHPC programme and EPSRC supported the initiative. We were therefore very pleased to be accepted as one of the first WHPC chapters, developing a chapter that encompasses all of the UK. We held a successful launch event in May, with attendees from different organisation from across the UK.

Lucia Michielin, currently working for the Software Sustainability Institute, tells us about the Edinburgh Carpentries effort and a networking event to be held on the 24th of May.

Edinburgh Carpentries, a new training initiative, was launched on September 2018 at the University of Edinburgh in collaboration with the Software Sustainability Institute. Since then the initiative has started to propagate to other institutes in the Edinburgh area, eg Heriot Watt University. Edinburgh Carpentries uses and leverages teaching materials and infrastructure from The Carpentries (carpentries.org.

Please visit us at Booth A-1453 at ISC 2019 in Frankfurt and vote us as your favourite team!

In the international ISC Student Cluster Competition (SCC), student teams build small clusters of different architectures to achieve the highest performance by running a series of applications and benchmarks under 3kW peak power limitation. The competition will be held in June in Frankfurt (Germany) as an integral part of the ISC High Performance Conference and Exhibition, and TeamEPCC will be there.

Using OpenRefine to create new datasets

Author: Mario Antonioletti
Posted: 28 Apr 2019 | 16:07

One of the benefits of teaching a Carpentry course is that it can increase or deepen your understanding of a subject. A recent instance for me was in using OpenRefine, a tool that runs locally on your machine (you do not have to export your data to a third party service).

OpenRefine can help you:
• Explore and clean/transform your data. You can reconcile your data with other external data sources, i.e. enrich your data using external data

• Create a new dataset. It does not modify your original data and keeps provenance of all the steps. Depending on the capabilities of your local machine it can deal with data sets that are up to about 100k rows.

Watch the videos on the OpenRefine website for a good overview. If you want to know more, follow the Carpentry OpenRefine for Ecologists lesson. In this example, I am going to show how easy is to generate a new dataset from the EPCC website. Follow along after you have installed OpenRefine on your system.

HPC Certification Programme: the HPC environment survey

Author: Weronika Filinger
Posted: 26 Apr 2019 | 13:31

We are embarking on a survey of the HPC environment and would appreciate your input! Jean-Thomas Acquaviva, DDN Storage, explains the background below.

Supercomputers are helping us to solve the world greatest challenges but who is helping us to harness the computational power of supercomputers?

The HPC Certification Forum is a community effort that aims to provide an international certification programme for the skills needed by practitioners  to harness supercomputers. It aims to clearly categorise, define, and examine competencies, which will be beneficial to all stake-holders involved in training and education. To make this effort relevant to the whole HPC community, a number of online surveys and polls will be created to capture and estimate the importance of the various tools, technologies, and skills expected from HPC practitioners.
