PRACE Summer of HPC (SoHPC) offers summer placements at HPC centres across Europe to late-stage undergraduates and/or Masters students. Up to twenty top applicants from across Europe spend two months working on projects related to PRACE technical or industrial work. Here are the three SoHPC visitors who are collaborating on projects with EPCC staff.

György Hantal was an HPC-Europa3 visitor from 18th March to 17th May 2019.

I am György Hantal (pictured here with Durham castle in the background), a postdoctoral researcher from the University of Vienna. I was an HPC-Europa3 visitor for two months, hosted by Dr. Lívia Bartók-Pártay at the University of Reading's Department of Chemistry and supported by EPCC in Edinburgh.

Preparing programming models for Exascale

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.

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.

HPC Certification Programme: the HPC environment survey

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.

Former HPC-Europa3 visitor Dr Mats Simmermacher, Dr Adam Kirrander (Mats' host from the University of Edinburgh's School of Chemistry), and their collaborators from Edinburgh and Copenhagen have recently published a paper in the prestigious Physical Review Letters where they discuss a new effect in ultrafast X-ray scattering. 

Spark-based genome analysis on Cray-Urika and Cirrus clusters

Analysing genomics data is a complex and compute intensive task, generally requiring numerous software tools and large reference data sets, tied together in successive stages of data transformation and visualisation.

Typically in a cancer genomics analysis, both a tumour sample and a “normal” sample from the same individual are first sequenced using NGS systems and compared using a series of quality control stages. The first control stage, ‘Sequence Quality Control’ (which is optional), checks sequence quality and performs some trimming. While the second one, ‘Alignment’, involves a number of steps, such as alignment, indexing, and recalibration, to ensure that the alignment files produced are of the highest quality as well as several more to guarantee the variants are called correctly. Both stages compromise a series of intermediately computing and data-intensive steps that very often are handcrafted by researchers and/or analysts.

Pablo C. Cañizares came on an HPC-Europa3 visit to EPCC from 23 July–24 October 2018. In this blog article he summarises his visit.

Hi there! I'm Pablo C. Cañizares, a PhD student in Computer Science from the Complutense University of Madrid (UCM), Spain. I work in the Design and Testing of Reliable Systems group in the Computer Science Faculty of the UCM. I visited EPCC for three months under the HPC-Europa3 transnational access programme and was hosted by EPCC's Dr David Henty.
