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.

Library booksIn 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".

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.
