University GPU Club: Tues 23 July 2013
Software for GPUs inc. compiler/directives, maths libs & tools (debuggers and profilers)
We are proud to announce that MathWorks (producers of MATLAB) and NVIDIA (producers of GPUs and CUDA) are coming to The University of Manchester on Tuesday 23 July to give presentations on how their products can be used by UoM researchers to dramatically reduce the time to solution for their simulations.
Presentations 10am - 1:30pm, Cordingley Lecture Theatre
- 10am: coffee
10:30am, Jeremy Purches, HPC Business Development Manager , NVIDIA: "NVIDIA GPU Technology"
11:30am, Jos Martin, Principal Architect for Parallel Computing Tools, Mathworks: "MATLAB: The challenges involved in providing a high-level language on a GPU"
- 12:30pm, lunch
Individual Workshops with NVIDIA and/or MathWorks 2pm-4pm, Hanson Room
An opportunity to meet and discuss with MathWorks and NVIDIA about your research and how they can help. This is appointment based (so you can meet in confidence) and all those who registered for an appointment have been contacted.
REGISTRATION has now closed although you are welcome to attend the morning session even if you have not registered (but will be required to sign the attendance form).
Both buildings are in Humanities Bridgeford Street.
Abstracts and Speaker Biographies
NVIDIA GPU Technology
NVIDIA invented the GPU (Graphics Processing Unit) in 1999 and, starting in visual computing, have expanded into supercomputing and, most recently, into cloud computing. NVIDIA’s CUDA parallel computing platform and programming model enables dramatic increases in computing performance, while their Tesla GPU accelerators help researchers and scientists by accelerating performance and energy efficiency.
This talk will introduce the audience to NVIDIA and GPU technology, before going into more detail on future roadmaps, GPU programming, tools & management and finally application performance. The first part of the presentation will be given by Jeremy Purches, HPC Business Development Manager. Jeremy has an extensive and deep understanding of HPC having previously worked for Rolls-Royce Aero-engines, EDS and HP before joining NVIDIA. The second, more technical, part of the presentation will be given by Dr Timothy Lanfear, Senior Solutions Architect. Timothy is an acknowledged HPC industry expert with a wide and deep technical knowledge of HPC, holding a PhD from Imperial College and previous positions at Clearspeed, Hitachi, BAE Systems and NATO.
MATLAB: The challenges involved in providing a high-level language on a GPU
MATLAB provides a high-level programming language and environment that is widely used for scientific computing across academia and various industries. GPUs provide fantastic computational power in a small package for certain classes of problem. Bringing these two together allows MATLAB programmers to solve bigger problems faster, but presents a number of technical challenges.
In this talk we will look at the ways in which we have tried to provide access to the power of the GPU without requiring the user to learn new programming techniques or breaking the standard MATLAB programming model. This presents several challenges: in defining a simple interface, in reproducing answers and in keeping the GPU busy. We will discuss some of these challenges and the ways in which we have chosen to address them.
Jos Martin is the principal architect for parallel computing tools at MathWorks, leading the team that develops tools for enabling parallel computing within the MATLAB environment. Before moving to a development role, he worked as a consultant in the U.K., writing large-scale MATLAB applications, particularly in the finance and automotive sectors. Prior to joining MathWorks in 2000, he held a Royal Society Post-Doctoral Fellowship at the University of Otago, New Zealand. His area of research was Experimental Bose-Einstein Condensation (BEC), a branch of low-temperature atomic physics.
Jos holds an M.A. in physics from St. Peter’s College, University of Oxford, and a D.Phil. in atomic and laser physics from Linacre College, University of Oxford. In 2008, on behalf of MathWorks, Jos was a joint winner of the HPC Challenge Class 2 award for Most Productive Implementation at Supercomputing 08.
