As ARCHER and the UK Research Data Facility (RDF) are both coming to the end of their service, many users will have to transfer their data to their own machines. Because of this, the ARCHER Data Transfer Guide has been updated to give more precise and up-to-date information about best practices for transferring data between ARCHER, the RDF, and remote machines.

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.

Posted: 16 Apr 2019 | 11:27

EPCC and EXDCI-2Funded by EXDCI-2, EPCC is organising a 2-day workshop in Edinburgh on 8-9 July 2019 to present ideas on how science and engineering can be supported from Raspberry Pis to large scale supercomputers. We are looking to investigate how to introduce these topics to school-age audiences including linking to existing school curricula. This will include examples of existing education materials and activities and looking ahead to current plans.

StethoscopeIn our role as members of the Research Engineering Group of the Alan Turing Institute, Anna Roubickova and I worked with Efi Tsamoura and Benjamin Spencer (Department of Computer Science at the University of Oxford) on PDQ, a proof-driven query planner that has great potential within the realm of data science for medical research. 

What is MPI “nonblocking” for? Correctness and performance

Author: Daniel Holmes
Posted: 27 Feb 2019 | 15:53

The MPI Standard states that nonblocking communication operations can be used to “improve performance… by overlapping communication with computation”. This is an important performance optimisation in many parallel programs, especially when scaling up to large systems with lots of inter-process communication.

However, nonblocking operations can also help with making a code correct – without introducing additional dependencies that can degrade performance.

The Fortissimo 2 project ended on 31 December 2018. Together with its predecessor (the plain old 'Fortissimo project') it has helped over 100 SMEs and mid-caps to run experiments that demonstrate the effectiveness of providing HPC services using a business model derived from cloud computing, thereby making it much lower risk for small companies to use HPC. 

Rocket surgery for PickCells

PickCells usability evaluation PickCells is image analysis software developed by the Centre for Regenerative Medicine (CRM) at The University of Edinburgh. PickCells allows biologists to explore multidimensional biological images of stem cell niches, organoids, and embryos. In late October, with the assistance of six researchers, we evaluated the usability of PickCells to help guide its future development.

To run our usability evaluation, we followed Steve Krug's highly-recommended and very readable book "Rocket Surgery Made Easy: The Do-It-Yourself Guide to Finding and Fixing Usability Problems". This book describes a practical way to carry out usability evaluations with minimal overhead.
