This article originally appeared in the Cisco blog by Jeff Squires and was written while I was undertaking a PhD before I joined EPCC as a member of staff. I thought it would be of interest to folks reading this blog.

My PhD involved building a message passing library using C#; not accessing an existing MPI library from C# code but creating a brand new MPI library written entirely in pure C#. The result is McMPI (Managed-code MPI), which is compliant with MPI-1 – as far as it can be given that there are no language bindings for C# in the MPI Standard. It also has reasonably good performance in micro-benchmarks for latency and bandwidth both in shared-memory and distributed-memory.

A library for changing between different data decompositions

I'm currently working on a small library to support decomposition changes in parallel programs.

It turns out that a fairly simple interface can be used to describe a very large space of possible data decompositions. I'm therefore writing a library that can redistribute data between any two such decompositions.

The high desert in New Mexico

I've recently returned from a very interesting week-long tour of the southwestern USA. Work-related, of course. I and a handful of European colleagues from the EUDAT project were graciously hosted by three groups all engaged in data infrastructure work on the other side of the Atlantic.

After flying into what must be one of the world's smallest and cutest airports in Santa Fe, our first stop was Los Alamos National Lab and the Web science group led by Herbert Van de Sompel.

Last Thursday (25th April) saw the prizegiving for the University Sustainability Awards. We've been involved with the awards for a few years now and have seen them change and adapt as we have. Last year EPCC won a Silver and this year we have achieved the top award, Gold.
