BSF 2013 Newcastle 7-12 Sept 2013

The programme for the British Science Festival 2013 in Newcastle has now been released and EPCC is running two events this year.The first is an exhibition booth in the Discovery Science Centre on Saturday 7th September, where we will be showing off a range of HPC demos including the Virtual Paleontology 'Dinosaur Racing' game currently being developed by one of our PRACE Summer of HPC students, as well as some other new ideas developed during Innovative Learning Week on our MSc, and of course a range of  HPC hardware old and new.

The Animal Simulation project, run at the University of Manchester, aims to create realistic simulations of animals both present and extinct. By combining the expertise of a number of scientific fields along with high performance computing (HPC), they have created GaitSym, a code capable of realistically simulating movements of animals based on a 3D model of their skeleton and biological data.

DiRAC driving test ready to roll

Since June 2012, The Software Sustainability Institute and Software Carpentry have been working with the DiRAC consortium to develop a "driving test" or basic software skills aptitude test. The test is now ready to be rolled out across DiRAC, the UK's integrated supercomputing facility for theoretical modelling and HPC-based research in particle physics, astronomy and cosmology.

MPI: sending and receiving in multi-threaded MPI implementations

Have you ever wanted to send a message using MPI to a specific thread in a multi-threaded MPI process? With the current MPI Standard, there is no way to identify one thread from another. The whole MPI process has a single rank in each communicator.

Are we underestimating the real challenge of Exascale?

Author: Mark Parsons

Reaching the Exascale is rightly posed as a combination of challenges related to (i) energy efficiency, (ii) heterogeneity and resiliency of computation, storage and communication, and (iii) the scale of the parallelism involved. Many discussions about Exascale focus on the first two challenges. This is understandable – building an Exascale system with today’s most energy efficient technology would still require around 480 MWatts.

Beatbox Workshop - Day 2

The second and final day of the Beatbox workshop that Adrian Jackson described yesterday consisted of a tutorial where some of the participants were walked through running Beatbox scripts and using Beatbox in general. 

The whole set-up was done using a bootable 8Gb Linux USB key which contained the key components, including part of the Beatbox distribution. That worked quite well and would be worth considering for this kind of course. The attendees got to take the USB keys away so they could continue evaluating Beatbox after the event, which is kind of neat.

I'm just preparing to give a talk, along with my colleague Mario, at the Beatbox workshop being held at Manchester University this week. Beatbox is an HPC environment for Biophysically and Anatomically Realistic

CP2K-UK: Now recruiting!

'CP2K-UK' is a new project starting shortly at EPCC, aiming to nurture the growth of a self-sustaining user and developer community around the CP2K materials science code here in the UK. I have been working on CP2K for nearly 5 years now thanks to a series of HECToR dCSE and PRACE projects, so it is great to get a chance to work on some of the more fundamental issues around usability and sustainability of the code, thanks to success in the EPSRC 'Software for the Future' call.

Following on from my recent post on Xeon Phi, thanks to the hard work of our Systems Development Team we now have a fully configured server sporting the two Intel 5110P Many Integrated Core (MIC) co-processor cards installed and ready to go. The imaginately named 'phi' machine is connected to our internal Hydra cluster and is available for staff, students and visitors to port and test their applications.

File transfer technologies for HPC systems

Introduction

While a surprisingly high proportion of HPC users are happy to keep their data on a single HPC service, or at most to move it within the hosting institution, sometimes is becomes necessary to move large volumes of data between different sites and institutions. As anyone who has ever tried to support users in this endeavour knows, it can be much harder to get good performance than it should be. This post is an attempt to document the available tools and technologies as well as common problems and bottlenecks.
