University of Melbourne Workshop: High-Performance GPU Computing with NVIDIA CUDA

May 12th, 2009

A half-day workshop and discussion forum will be held from 8:45-13:00, Wednesday May 27, in Lecture theatre 3 of the Alan Gilbert Building at The University of Melbourne, Victoria, Australia. A  light lunch will be supplied afterwards from 13:00-14:00. With speakers from NVIDIA and Xenon Systems, this workshop is hosted by the ARC Centre of Excellence for Mathematics and Statistics of Complex Systems (MASCOS), and the Department of Mathematics and Statistics at the University of Melbourne.

Due to recent advances in GPU hardware and software, so called general-purpose GPU computing (GPGPU) is rapidly expanding from niche applications to the mainstream of high performance computing. For HPC researchers, hardware gains have increased the imperative to learn this new computing paradigm, while high level programming languages (in particular, CUDA) have decreased the barrier to entry to this field, so that it is now possible for new developers to rapidly port suitable applications from C/C++ running on CPUs to CUDA running on GPUs. For appropriate applications, GPUs have significant, even dramatic, advantages compared to CPUs in terms of both Dollars/FLOPS and Watts/FLOPS.

Barra: A Modular Functional GPU Simulator

May 4th, 2009

Barra, developed by Sylvain Collange, Marc Daumas, David Defour and David Parello from Université de Perpignan, simulates CUDA programs at the assembly language level (NVIDIA PTX ISA). Its ultimate goal is to provide a 100% bit-accurate simulation, offering bug-for-bug compatibility with NVIDIA G80-based GPUs. It works directly with CUDA executables; neither source modification nor recompilation is required. Barra is primarily intended as a tool for research on computer architecture, although it can also be used to debug, profile and optimize CUDA programs at the lowest level. For more details and downloads, see the Barra wiki. A technical report is also available.

University of Western Australia GPU Computing Workshop

April 29th, 2009

A GPU computing workshop and discussion forum will be held at the UWA University Club Thursday, May 7th.  The workshop aims to provide a detailed introduction to GPU computing with CUDA and NVIDIA Tesla computing solutions, and to present research in GPU and Heterogeneous computing being undertaken in Western Australia.

Mark Harris (NVIDIA) will present an introduction to the CUDA architecture, programming model, and the programming environment of C for CUDA, as well as an overview of the Tesla GPU architecture, a live programming demo, and strategies for optimizing CUDA applications for the GPU. To better enable the uptake of this technology, Dragan Dimitrovici from Xenon Systems will provide an overview of CUDA enabled hardware options. The workshop will also include brief presentations of some of the projects using CUDA within Western Australia, including a presentation from Professor Karen Haines (WASP@UWA) on parallel computing strategies required for optimizing applications for GPU and heterogeneous computing.

Please see the workshop flyer for full details.

NVIDIA First to Roll out OpenCL Drivers & SDK

April 20th, 2009

From an NVIDIA Press Release:

SANTA CLARA, CA—APRIL 20, 2009—NVIDIA Corporation, the inventor of the GPU, today announced the release of its OpenCL driver and software development kit (SDK) to developers participating in its OpenCL Early Access Program. NVIDIA is providing this release to solicit early feedback in advance of a beta release which will be made available to all GPU Computing Registered Developers in the coming months.

Developers can apply to become a GPU Computing Registered Developer at: www.nvidia.com/opencl

“The OpenCL standard was developed on NVIDIA GPUs and NVIDIA was the first company to demonstrate OpenCL code running on a GPU,” said Tony Tamasi, senior vice president of technology and content at NVIDIA. “Being the first to release an OpenCL driver to developers cements NVIDIA’s leadership in GPU Computing and is another key milestone in our ongoing strategy to make the GPU the soul of the modern PC.”

At the core of NVIDIA®’s GPU Computing strategy is the massively parallel CUDA™ architecture that NVIDIA pioneered and has been shipping since 2006. Accessible today through familiar industry standard programming environments such as C, Java, Fortran and Python, the CUDA architecture supports all manner of computational interfaces and, as such, is a perfect complement to OpenCL. Enabled on over 100 million NVIDIA GPUs, the CUDA architecture is enabling developers to innovate with the GPU and unleash never before seen performance across a wide range of applications.

eResearch South Australia Workshop: High Performance GPU Computing with NVIDIA CUDA

April 14th, 2009

This workshop,  hosted by eResearch SA and to be presented by Mark Harris (NVIDIA) with Dragan Dimitrovici (Xenon Systems), aims to provide a detailed introduction to GPU computing with CUDA and NVIDIA GPUs such as the Tesla series of high-performance computing processors.

The workshop will be held from 9:00-13:00 on Tuesday 28th April, in the Henry Ayers Room, Ayers House
288 North Terrace, Adelaide (opposite the Royal Adelaide Hospital).

CUDA is NVIDIA’s revolutionary parallel computing architecture for GPUs. The available software tools include a C compiler for developers to build applications, as well as useful libraries for high-performance computing (BLAS, FFT, etc). Several widely-used scientific applications have been ported to run on GPUs using CUDA. This half-day workshop will provide an introduction to the CUDA architecture, programming model, and the programming environment of C for CUDA, as well as an overview of the Tesla GPU architecture, a live programming demo, and strategies for optimizing CUDA applications for the GPU. The workshop will also include a brief presentation of some of the current NVIDIA hardware offerings for GPU computing using CUDA.

The workshop is free, but space is limited. For complete details and registration, visit the workshop web page or download the brochure.

Molecular dynamics on NVIDIA GPUs with speed-ups up to two orders of magnitude

April 13th, 2009

ACEMD is a production-class bio-molecular dynamics (MD) simulation program designed specifically for GPUs which is able to achieve supercomputing scale performance of 40 nanoseconds /day for all-atom protein systems with over 23,000 atoms.  With GPU technology it has become possible to run a microsecond-long trajectory for an all-atom molecular system in explicit water on a single workstation computer equipped with just 3 GPUs. This performance would have required over 100 CPU cores.  Visit the project website for details.

GPU VSIPL is an implementation of Vector Signal Image Processing Library that targets Graphics Processing Units (GPUs) supporting NVIDIA’s CUDA platform. By leveraging processors capable of 900 GFLOP/s or more, your application may achieve considerable speedup without any specialized development for GPUs. The GPU VSIPL range-Doppler map application achieved a 75x speedup on the GPU simply by linking it with GPU VSIPL.

GPU VSIPL is currently released as a static library, and all releases are verified with the VSIPL Core Lite Test Suite.

GPU VSIPL was presented to the High Performance Embedded Computing Workshop 2008. Read the GPU VSIPL extended abstract [PDF].For more information, visit the GPU VSIPL Website.
