Intel Parallel Computing Centre: progress report

EPCC's Grand Challenges Optimisation Centre, an Intel Parallel Computing Centre which we announced earlier in the year, has made significant progress over recent months. 

The collaboration was created to optimise codes for Intel processors, particularly to port and optimise scientific simulation codes for Intel Xeon Phi co-processors. As EPCC also runs the ARCHER supercomputer, which contains a large number of Intel Xeon processors (although no accelerators or co-processors), for EPSRC and other UK research funding councils, we also have a strong focus on ensuring that scientific simulation codes are highly optimised for these processors. Therefore, the IPCC work at EPCC has been concentrating on improving the performance of a range of codes that are heavily used for computational simulation in the UK on both Intel Xeon and Intel Xeon Phi processors.

The Nu-FuSE (Nuclear Fusion Simulations at Exascale) project was a 3-year, G8 funded, international research project to investigate the challenges and requirements for fusion simulations at Exascale levels. The project’s aim was to significantly improve computational modelling capabilities for fusion, and fusion-related sciences, enhancing the predictive capabilities needed to address key physics challenges of a new generation of fusion systems. 

The Auditory Project – an investigation into modelling the human ear using HPC

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.

Heterogeneous HPC architectures are becoming increasingly prevalent in the Top500 list with CPU-based nodes being enhanced by accelerators or coprocessors optimized for floating-point calculations. This trend is likely to increase as we move towards Exascale (1018 flops) capable systems and it is vital that the relevant HPC applications are able to exploit this heterogeneity [1, 2].

EPCC will be exhibiting in Booth 920.

International Supercomputing Conference (ISC) is one of the main events in the field of high performance computing, networking and storage. It has a diverse programme of keynote talks, research presentations, tutorials, BoFs and satellite events provided by 300 expert speakers along with over 170 exhibitors and 3,000 attendees. As usual, there will be a significant EPCC representation.

Dr Jason Beech-Brandt, Manager Exascale Research, Europe at Cray writes about the CRESTA project, which is addressing the challenges of exascale computing.

Seymour Cray, the pioneer of supercomputing, famously asked if you would rather plough a field with two strong oxen or 1024 chickens.

Pervasive Parallelism PhD studentships at EPCC

EPCC was recently successful in its joint bid with Informatics for an EPSRC Centre for Doctoral Training in Pervasive Parallelism. The Centre aims to develop research leaders with deep knowledge and awareness across the parallelism spectrum. To support this, it will support about 10 fully-funded, four-year studentships each year over the next 5 years. The majority will be based in Informatics, but we expect 1 or 2 per year to be available at EPCC.
