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.

EPCC staff supported Dr Rincon Bonilla in his HPC-Europa3 research visit to the University of St Andrews earlier this year. 

My name is Mauricio Rincon Bonilla. I work as a postdoctoral fellow at the Basque Centre for Applied Mathematics in Bilbao, Spain, where I combine advanced sampling methods with physico-chemical insights to investigate ion dynamics in advanced battery materials. With the sponsorship of an HPC-Europa3 grant, I was able to spend seven weeks at the University of St Andrews with my hosts Prof. Tanja van Mourik and Herbert Fruchtl, who have lots of expertise in density functional theory for biological and inorganic materials.

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.

IoT Research and Innovation service

Guest blogger Simon Chapple introduces the University of Edinburgh's IoT Research and Innovation Service.

Most people will have heard of the Internet of Things (IoT). It is a hot topic in technology, business and the mainstream news, projected as it is to underpin a future trillion-dollar market at least as large as, and by some estimations even greater than, the cloud-based computing services industry. We define IoT as a network of dedicated physical objects that contain embedded technology to sense and interact with the external environment, and that can connect and exchange data.

Giuseppe Negro undertook an HPC-Europa3 visit based in Edinburgh from 15/04/19–27/05/19. He gives us a brief overview of his visit and the work he undertook.

Hi everyone! My name is Giuseppe Negro and I am a PhD student at the University of Bari in Italy. I work in computational modelling of soft matter systems with Prof. Giuseppe Gonnella and with my collegue Livio Nicola Carenza, who was also an HPC-Europa3 visitor in Edinburgh, at the Department of Physics in Bari. I visited EPCC under the HPC-Europa3 transnational access programme, and I was hosted by Prof. D. Marenduzzo at the Department of Physics and Astronomy of the University of Edinburgh located at the James Clerk Maxwell Building.

Privacy, transparency and control: disrupting the charitable-giving sector

EPCC has been working closely with Edinburgh-based fintech company Sustainably, supporting its rapid growth in the charitable giving sector. Here Loral Quinn, Co-founder and CEO at Sustainably, describes our collaboration.

Sustainably is disrupting a $400 billion market by making it easier for businesses and consumers to have a positive impact every day by rounding up cashless transactions and donating spare change to causes they care about automatically every time they shop.
