Festival Mobility: decisions with data

If you’ve lived in Edinburgh during August, you’ve witnessed a city transformed. Together, Edinburgh’s August festivals represent an annual event close to the size of the Olympic Games. It takes a gargantuan effort by everyone involved with running the city and they do a great job. Those of us who live in Edinburgh during Festival time know that, when dealing with so many people, things don’t always work as well as we’d like. Our commutes may be longer. We might have to stand on the train or walk in the bus lane to bypass the crowds. Edinburgh’s festivals are the envy of the world but can make life more difficult for many of it citizens.

Eef van Dongen visited the University of St Andrews from 23 September–11 October 2019 through the HPC-Europa3 transnational access programme. In this post she describes her work on improving iceberg-calving simulation techniques.

Hi! My name is Eef van Dongen. I am a PhD student in glaciology at ETH Zurich. This autumn I visited Dr Joe Todd in the research group of Professor Doug Benn based at the University of St Andrews for three weeks with HPC-Europa3. My research focuses on iceberg-calving – the breaking off of icebergs at the edge of glaciers into the sea – which is responsible for approximately half of the ice mass loss of the Greenland ice sheet.

Nicolas Sieffert was an HPC-Europa3 visitor to the University of St Andrews in summer 2018 and again in 2019. In this blog post he describes his two trips to Scotland.

Hi there! I am Nicolas Sieffert, associate professor in computational chemistry at the University Grenoble Alpes (France). I visited the UK for nine weeks under the HPC-Europa3 transnational access programme and was hosted by Prof. M. Bühl at the University of St Andrews (UK), with HPC resources and technical assistance provided by EPCC.

Exploring the binding mechanism of glycomimetics to galectins through simulations

Domenica Capasso was an HPC-Europa visitor to University College London from 12 June to 11 August 2019. In this blog article she describes her work and time in London.

In June this year, I returned to London and I spent two months at the Department of Chemistry at UCL, funded by HPC-Europa and hosted by Professor Francesco Luigi Gervasio. My project concerns the galectins, β-D-galactoside binding proteins with important implications for tumorigenesis, inflammatory response and autoimmune disorders. During my first visit, we created a virtual library of candidate compounds, containing two saccharide residues with a bridging sulphur/selenium atom. These derivatives, targeting galectins, were obtained using structure-based drug design approaches and are synthesised and tested in my Institute in Naples.

Gladys Utrera was an HPC Europa3 visitor to EPCC from 1st of July to the 3rd of August 2019. She has been an HPC Europa visitor before - in this brief blog article she tells us what she did this time.

Hi! My name is Gladys Utrera and I currently work at the Computer Architecture Department of the Universitat Politècnica de Catalunya in Barcelona, Spain. There I combine teaching of parallel computing and operating systems subjects with research on HPC topics and parallel programming models. Thanks to the HPC-Europa3 programme I could spend four weeks at the EPCC in the University of Edinburgh with my host Mark Bull who is a very well-known expert in my research areas. This is my third research visit to EPCC, and the second as an HPC-Europa visitor. 

My research involves executions on large multi-core node clusters. In addition, performance evaluations on machines with different architectures characteristics like ARCHER and Cirrus, enrich my results greatly.

Edoardo Coronado visited EPCC from 18th May–15th August 2019 under the HPC-Europa3 programme. 

Hi! My name is Edoardo Coronado. I am a Mexican PhD student in Technologies of Information at the "Centro Singular de Investigación en Tecnoloxías Intelixentes" (CiTIUS) at the "Universidad de Santiago de Compostela" in Spain. I work on the optimisation of iterative solvers on accelerator devices. I have spent three months at EPCC at the University of Edinburgh under the HPC-Europa3 transnational access programme with Mr Adrian Jackson acting as my host.

PRACE SoHPC: Wee Archie project overview

Caelen Feller, a PRACE Summer of HPC (SoHPC) student working with Wee Archie, gives us an overview and status report of his project.

As I have said previously, I’m working with Wee ARCHIE, EPCC's mini supercomputer, this summer. Wee Archie is made of 16 Raspberry Pi chips – each very small, lightweight computers connected together to work as a single machine. With each chip is an attached LED panel, allowing me to display what is occurring on the chip and how it is communicating to other chips. I have created a series of tutorials and simple demonstrations to be run on Wee Archie which explain the basics of message passing using MPI to a complete novice in parallel computing and non-expert in computers in general.
