This year’s facilities sharing event, Get Your Kit Out Too, takes place on June 11 and with the usual funding for equipment severely squeezed, why not come and see what's on your doorstep, and how it can work for you? There will be talks, exhibitions and networking to help you discover the kit and facilities available at the College of Science and Engineering and find out how you can access them. Building on last year's successful and informative day, this year's event will also feature facilities from outwith the College, including those at Heriot-Watt and St Andrews universities.

Opening OpenACC

Author: Ruyman Reyes Castro

Programmability of GPUs (or accelerators in general) has improved since the days of the OpenGL shaders. First CUDA, and OpenCL later, have evolved to offer a reasonable way of programming efficient algorithms onto GPUs. However, despite this improvement, there is still a lot of effort involved in the development of code for accelerators. This is inevitable sometimes: if you have a particular algorithm and you want to have the maximum performance possible for a particular accelerator architecture, and you have the time to do it, you can immerse yourself in the marvellous world of CUDA/OpenCL low-level optimisation and stop reading. If time is critical for you, as it is for me, then you will love the latest advance in accelerator programmability: OpenACC.

BitBucketing MSc students

Based on previous experience of supervising MSc students and inspired by the Software Carpentry boot camp sessions I attended as a helper in Edinburgh and Newcastle, I thought I would insist that the MSc students that I am supervising this year should use a third party private source code repository for their code, meeting minutes, project report and project presentation and anything else that might be of relevance.

Dinosaurs in Europe!

Day 1 of the fifth PRACE industry seminar, and attendance is high, despite losing a delegate in the tour of the Mercedes production line this morning (really!). A day of interesting talks but I think the main outcome has been the opportunity for potential collaborators to meet, make new contacts and get the best advice as to how to enhance their business via HPC.

Software Carpentry highlights at the EGI Forum

At last week's EGI Forum, I delivered a day of Software Carpentry boot camp "highlights" as part of The Software Sustainability Institute's training activities. These were taster sessions drawn from Software Carpentry's highly successful

From multi to many cores: Intel Xeon Phi at EPCC

Two shiny new Intel Xeon Phi 5110P co-processors have recently arrived at EPCC.

Based on Intel's Many Integrated Core (MIC) architecture, each card comprises 60 cores with 4-way SMT and a 512 bit wide SIMD vector unit.  At a clock speed of 1.053 GHz, this gives an aggregate peak double precision floating point performance of 1.01 TFLOP/s - all in a PCI card package, and using less than 225 Watts of power.  

Energy Efficient Computing - Call for papers extended to May 15th 2013

The deadline has been extended for submission of papers to the special session on Energy Efficient Systems at the 2013 IEEE International Conference on Systems, Man and Cybernetics.

Launching applications non-homogenously on Cray supercomputers

Author: Tom Edwards
Posted: 12 Apr 2013 | 11:31

The vast majority of applications running on HECToR today are designed around the Single Instruction Multiple Data (SIMD) parallel programming paradigm. Each processing element (PE), i.e. MPI rank or Fortran Coarray image, runs the same program and performs the same operations in parallel on the same or a similar amount of data. Usually these application are launched on the compute nodes homogenously, with the same number of processes spawned on each node and each with the same number of threads (if required).
