Applying graphics hardware to achieve extremely fast geometric pattern matching

April 5th, 2009


We present a GPU-based approach to geometric pattern matching. We reduce this problem to ?nding the depth (maximally covered point) of an arrangement of polytopes in transformation space and describe hardware-assisted (GPU) algorithms which exploit the available set of graphics operations to perform a fast rasterized depth computation.

gDEBugger for Apple Mac OS X launched at GDC 2009

March 31st, 2009

Graphic Remedy launched the first official version of gDEBugger Mac at this year’s Game Developers Conference, held in San Francisco, 23-27 March. On Tuesday March 24, gDEBugger Mac was demonstrated in the Khronos Developer University full-day tutorial area. A fully functional trial version of gDEBugger Mac is now available for download.

gDEBugger is an OpenGL Debugger and Profiler. It traces application activity on top of the OpenGL API, lets programmers see what is happening within the graphics system implementation to find bugs and optimize OpenGL application performance.

gDEBugger Mac brings all of gDEBugger’s Debugging and Profiling abilities to the Mac OS X OpenGL developer’s world. gDEBugger now runs on Windows, Mac OS X and Linux operating systems.

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.

Minisymposium on GPU Computing at PPAM 2009

March 23rd, 2009

Submissions of relevant research on GPU Computing are invited to this minisymposium, organized as part of the 2009 International Conference on Parallel Processing and Applied Mathematics (PPAM 2009: Wroclaw, Poland, September 13-16, 2009) by April 10, 2009. Topics of interests include, but are not limited to, the development of techniques and tools (e.g., compilers, high-level application programming interfaces, etc.) that improve the programmability of GPUs as well as practical demonstrations of the potential of GPUs in the solution of scientific, engineering and commercial applications. Best papers presented at the minisymposium will be considered for a special issue of Concurrency and Computation: Practice & Experience. For further details, visit GPUCOMP2009.

SIAM CSE’09: Scientific Computing on Emerging Many-Core Architectures

March 17th, 2009

Slides are now available for the minisymposium “Scientific Computing on Emerging Many-Core architectures”, held in conjunction with the SIAM Conference on Computational Science and Engineering 2009 (SIAM CSE’09, Miami, Florida). The minisymposium, organised by Mike Giles, Dominik Göddeke and Stefan Turek, focused on opportunities and challenges for scientific computing on novel many-core architectures, in particular IBM’s Cell processor and GPUs from NVIDIA, AMD and Intel. The talks covered a range of application areas, including the development of libraries and other tools to simplify the programming many-core processors.
