MVAPICH is a high performance implementation of MPI. It is specialised for InfiniBand, Omni-Path, Ethernet/iWARP, and RoCE communication technologies, but people generally use the default module loaded on their system. This is important because, as HPC programmers, we often optimise our codes but overlook the potential performance gains of better choice of MPI implementation.

In this blog post I consider how we (as the UK HPC community) could create a community HPC technical knowledge base that would allow us to share and reuse useful technical information. Much of these thoughts came out of discussions at the HPC Champions meeting that took place on 16 September 2019 alongside the UK RSE Conference 2019 in Birmingham, UK along with subsequent discussions at the monthly HPC RSE calls.

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.

Hi! My name is Concetta Cozza. I am a PhD student in Life Science at University ‘Magna Graecia’ of Catanzaro. This summer I visited the research group of Professor Michele Vendruscolo based at the University of Cambridge for three months with the HPC-Europa3 transnational access programme.

As part of the NEXTGenIO project we have a prototype HPC system that has two Intel Omni-Path networks attached to each node. The aim of having a dual-rail network setup for that system is to investigate the performance and functionality benefits of having separate networks for MPI communications and for I/O storage communications, either directing Lustre traffic and MPI traffic over separate networks, or using a separate network to access NVDIMMs over RDMA. We were also interested in the performance benefits for general applications exploiting multiple networks for MPI traffic, if and where possible.

The highly successful NEXTGenIO project is now drawing to a close after nearly four years. EPCC colleagues will be at ISC19 presenting the results of the project at a booth presentation, a BoF, and a workshop presentation. Come along and find out more!

The Advanced Computing Facility (ACF) on the outskirts of Edinburgh is the high performance computing data centre of EPCC.
Built in the 1970s and operated by EPCC since the turn of the millennium, the ACF site has had significant investment over the years. At present, there are three Computer Rooms, imaginatively called: Computer Room 1 (CR1), Computer Room 2 (CR2), and Computer Room 3 (CR3).
