I promised in a post last month that I'd write some more about the PrimeGrid project, and it so happened this week that we made a discovery which gives me a good excuse to blog! On 31st October 2016 at 22:13:54 UTC a computer owned by Péter Szabolcs of Hungary reported via the BOINC distributed computing software that the number 10223*231172165+1 was prime.

Nektar++  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.

It's always a bit of an embarrassment when talking about your code tests. I think most developers know that they don’t have enough tests or that their tests are not good enough.
There is never enough time to either write or to run tests that fully cover all possibilities so, like all types of programming, testing becomes a compromise where you try to make the best use of the limited resources available for testing.

Number Theory - the study of the integers - is perhaps one of the purest branches of maths and is not well-known for setting the headlines alight.
Along with the proof of Fermat's Last Theorem in 1995, which earned a knighthood for Sir Andrew Wiles, there was a lot of excitement about the Twin Prime Conjecture a few years ago, beginning a new spurt of progress towards the solution of this thorny mathematical problem.

September seems to have passed by in a bit of a blur, and it's already a whole month since the CP2K Summer School, which we ran at King's College London (23-26th August), so I thought it would be a good time to give an update on the recent activities of the CP2K-UK project.

Developing for the real world
As part of a recent ARCHER eCSE project I developed a new parallelisation strategy for a computational simulation application to enable it to scale efficiently to larger process counts. We managed to significantly reduce the parallel overheads, so the code was accepted into the main repository for users to exploit.

BGTB is a family-friendly science festival held every September in the Scottish Borders - this is the fifth year in a row we've run a workshop there and it was good to see some repeat visitors from previous years as well as new faces, eager to find out about HPC and Computer Simulation.
