45 minutes is a long time for a computer: 2,700 long seconds. For a supercomputer like ARCHER that's a lot of time to spend getting ready to do work, but this is the problem faced by the firedrake team who we work with as part of the Marine Technology project.

Application performance

As part of the ARCHER Knights Landing (KNL) processor testbed, we have produced and collected a set of benchmark reports on the performance of various scientific applications on the system. This has involved the ARCHER CSE team, EPCC's Intel Parallel Computing Center (IPCC) team, and various users of the system all benchmarking and documenting the performance they have experienced.

Nektar++ [1] is an open-source MPI-based spectral element code that combines the accuracy of spectral methods with the geometric flexibility of finite elements, specifically, hp-version FEM. Nektar++ was initially developed by Imperial College London and is one of the ExaFLOW co-design applications being actively developed by the consortium. It supports several scalable solvers for many sets of partial differential equations, from (in)compressible Navier-Stokes to the bidomain model of cardiac electrophysiology.

We are pleased to announce the third ARCHER Image Competition, and we invite all users of the national supercomputing service to share their images on the theme of "ARCHER Enabling Research".

ARCHER Champions: spreading the word

ARCHER Champions began with a vision: every research organisation that could benefit from ARCHER should have someone local who knows about the routes to access ARCHER and who can help potential users to get started.

We want Champions to tell us how we can improve support for them and their local users, and how to start joining up all the HPC facilities and the people with the expertise around the UK.

Intel compiler on ARCHER

Bug

I had a recent query from some users with a problem with the default version of the Intel Fortran compiler on ARCHER (v15.0.2.164).  It was a nice query to get because the users had done all the work already; they'd identified the problem, found a test code that demonstrated it, and told me what the solution would be for them.

Fortunately, the solution was easy, this bug has been fixed in a newer version of the compiler (16.0.2.181), which is installed and available on ARCHER, but just isn't the default (we tend to keep the default version slightly behind the latest release but as new as possible), so they simply have to swap the compiler modules then their code can compile and run correctly.

Broadening participation in HPC: taking outreach to the next level

Learning about SAFE at ARCHER Champions

One of the reasons why EPCC set up Women in HPC is because we recognised there was a problem. The problem was the apparent lack of women in the supercomputing community. When my colleagues and I started Women in HPC, our purpose was very clear: to recruit and retain women in the international HPC workforce.

Day five of the Big Bang Fair, our busiest day yet and Mario left us to return back to Edinburgh. The previous evening we all attended the supporter’s dinner, where the Young Scientist and Young Engineer of the year were announced. It was followed by a three course sit down dinner with people from industry, the exhibitors and other guests.
