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.

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.

With jobs submitted to a batch system, supercomputing has traditionally been centred around an offline, non-interactive approach to running codes such as simulations. However, it is our belief that there is great potential in fusing HPC with real-time data for use as part of urgent decision-making processes in response to natural disasters and crises.

The SpiNNaker neuromorphic high-performance computing platform, which aims to run 1% of the human brain in real time, will arrive at EPCC in the Bayes building this year. SpiNNaker is a novel hardware platform due to its massive parallelism, multi-cast communication fabric and low power design.

Dr Martin Lepšík came on an HPC-Europa3 visit from 16-29 July and was hosted by Dr Emanuele Paci at the University of Leeds. Martin started his visit by coming to Edinburgh.
My name is Martin Lepšík, and I am a Czech computational structural biologist. After 11 years of fruitful research in quantum mechanics-based drug design (at P. Hobza’s group at IOCB, Prague, CR), I decided to enrich my expertise with enhanced-sampling molecular dynamics of lectin-carbohydrate complexes, important for human health and disease.

The EU has recently funded a significant number of new projects to continue to drive forward Europe’s readiness for the transition to exascale computing. As a result EPCC will add another three projects to its portfolio of exascale activities.

In the March 2018 meeting of the MPI Forum, the “Persistent Collectives” proposal began the formal ratification procedure, the “Sessions” proposal took a step forward, but the “Fault Tolerance” saga took a step side-ways.
The proposal to add persistent collective operations to MPI was formally read at the March meeting, and was well-received by all those present. The first vote for this proposal will happen in June and the second vote in September. If all goes well, this addition to MPI will be announced at SC18.

Miriam Ruiz Ferrández was a recent HPC-Europa3 visitor to Edinburgh who used EPCC resources while being hosted by Napier University. In this article she relates some of her findings and experiences.
Hi everyone! I am a PhD student at the University of Almería, which is located in the south-east of Spain. I spent three months in Edinburgh funded by the HPC-Europa3 programme working on a project entitled: “A Parallel Multi-Objective Algorithm for Optimizing High-Pressure/Temperature Treatments in the Food Industry”. During this research stay, I was collaborating with Professor Ben Paechter at Edinburgh Napier University and I used computing resources provided by EPCC at the University of Edinburgh.
