Sharing of resources has challenges for the performance and scaling of large parallel applications. In the NEXTGenIO project we have been focusing specifically on I/O and data management/storage costs, working from the realisation that current filesystems will struggle to efficiently load and store data from millions of processes or tasks all requesting different data sets or bits of information.

The iCAIRD project is working to establish a world-class centre of excellence in the application of artificial intelligence to digital diagnostics. The intention is that iCAIRD will allow clinicians, health planners and industry to work together, enabling research-active clinicians to collaborate with innovative SMEs to better inform clinical questions, and ultimately to solve healthcare challenges more quickly and efficiently.

Since the start of the ARCHER UK National Supercomputing Service service, one hundred eCSE (embedded Computational Science and Engineering) projects have been awarded funding to carry out code improvements for software running on ARCHER and future Tier-1 services. Projects have come from a diverse range of disciplines with principal investigators (PIs), Co-Investigators (Co-Is) and technical staff involved from 44 different institutions across the UK.

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.

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.

The recent installation of Fulhame, the ARM HPC machine based here in EPCC as part of the Catalyst UK programme, raises plenty of interesting opportunities for exploring the HPC software ecosystem for ARM. One such aspect is the relative performance of different MPI implementations on these machines and this is what I was talking about last week at the MVAPICH User Group (MUG) workshop.

In our October 2018 blog post on Analysing humanities data using Cray Urika-GX, we described how we had been collaborating with Melissa Terras of the College of Arts, Humanities and Social Sciences (CAHSS) at The University of Edinburgh to explore historical newspapers and books using the Alan Turing Institute's deployment of a Cray Urika-GX system ("Urika"). In this blog post we describe additional work we have done, to look at the origins of the term "stranger danger", find reports on the Krakatoa volcanic eruption of 1883, and explore the concept of "female emigration".
