Last week I was lucky enough to spend a few days in the tropical city of Singapore, attending the Computational Mathematics, Computational Geometry & Statistics (CMCGS) 2015 conference. I was there to present a review paper on the achievements of the PrimeGrid project, which I have blogged and talked about before, but as a more mathematical rather than computationally-themed conference, it was also a good chance to make contact with researchers who might be less au fait with parallel computing than most.

For the last few years, I have had the opportunity to collaborate with Prof. Michael Fagan of the Medical and Biological Engineering group at the University of Hull on the development of his VOX-FE voxel finite-element (FE) bone modelling software. Past projects under EPSRC and HECToR dCSE funding allowed us to improve the scaling of the core solver and implementent parallel I/O, but it has become increasingly apparently that this was papering over the cracks, and a complete re-engineering of the code base would be required to make it portable, scalable and flexible enough to be useable.

The Adept project is addressing the challenge of the energy-efficient use of parallel technologies. It builds on the expertise of software developers from high-performance computing to exploit parallelism for performance, and on the expertise of Embedded systems engineers in managing energy usage. Adept is developing a tool to guide software developers and help them model and predict the power consumption and performance of parallel software and hardware.

EPCC helped lead the way in creating the standardised Message-Passing Interface (MPI) programming system to enable faster, more powerful, problem solving using parallel computing. It is now the ubiquitous de-facto standard among both hardware and software vendors.

The Auditory pilot project investigated the use of HPC to enable faster run times for computational models of the human cochlea. It was a collaboration between EPCC and Dr Michael Newton of the University of Edinburgh’s Acoustics and Audio group.
We began with an existing cochlea model code written in Matlab, which took many hours to run on a single processor. Our initial profiling of the Matlab code showed that almost the entire runtime (see Figure 1) was taken up by this solver and thus any attempts to parallelise the code would require a C/C++ replacement to be found.

As well as helping out with our drop-in workshop at the British Science Festival in early September, I also had the chance to give a talk as part of the Festival's public lecture programme. Over 75 people turned out early on Sunday morning to hear 'Seventeen or Bust: Solving hard mathematical problems with your help!', where I explained how the PrimeGrid project is working on a solution to Sierpinski's conjecture, a fifty-year-old unsolved problem in Number Theory, as well as finding record-sized prime numbers in the process.

The Fortissimo project, which is coordinated here at EPCC, gives companies a low-risk opportunity to try out HPC. By combining it with cloud computing, they can gain the benefits without buying and running their own systems. Here are three examples of HPC in action under Fortissimo.
