In addition to the papers already announced, Dr. Simon Harding (Memorial University, Newfoundland) and Dr. Tien-Tsin Wong (The Chinese University of Hong Kong) will lead a discussion on the practicalities of running evolution on modern graphics cards. They will contrast the current leading GPGPU tools considering ease of use, and support for debugging and performance monitoring. CIGPU will close with a short session considering the future of computational intelligence on GPUs.

Slides from the 2007 AstroGPU conference, held at the Institute for Advanced Study in Princeton last November, have been posted to the AstroGPU Website.

In conjunction with The 2008 International Conference on Computational Science and Its Applications (ICCSA 2008, UCHPC ’08 is a technical session on UnConventional High Performance Computing. This session focuses on uses of hardware for HPC that was not originally intended for HPC. UCHPC invites papers on all aspects of unconventional HPC and its related areas describing either proven and tested solutions or novel ideas and concepts. Topics for submissions include but are not limited to the following areas: cluster solutions; performance issues and scalability; innovative use of hardware and software; and HPC on GPUs, Cell BE, FPGAs and other hardware. Please see the Call for Papers for more information.

ARCS 2008, the 21st Conference on Architecture of Computing Systems, is proud to announce a full day GPGPU tutorial, covering concepts, building blocks and case studies with a special focus on NVIDIA CUDA GPU Computing technology. ARCS is held in Dresden, Germany, on February 25-28, 2008. For more details, please visit The ARCS 2008 Website.

The CIGPU-2008 special session on computational intelligence using consumer games and graphics hardware invites submissions of novel scientific and engineering applications of GPUs. Papers submitted for special sessions will be peer-reviewed with the same criteria used for the contributed papers. Submission deadline is 7 January 2008.

The Workshop on General Purpose Processing on Graphics Processing Units will be held October 4, 2007 at Northeastern University, Boston, MA. This meeting will include a keynote talk by Prof. Wen-mei Hwu on “GP Computing: Hardware, Architecture Tools and Education”.

The program will include three invited talks from NVIDIA, ATI and IBM Research, and will include demos by GPU hardware and software vendors. The technical program will include 12 refereed papers. Registration is free, though you need to register for The Workshop on GPGPU at: http://censsis-db3.ece.neu.edu/RICC2007/regist.aspx

Commercial companies that are interested in presenting at The Workshop on GPGPU, please contact the organizing committee at gpgpu@ece.neu.edu.

On Sunday November 11 2007 at SC07 in Reno NVIDIA will host a full-day tutorial on CUDA. In this tutorial NVIDIA engineers will partner with academic and industrial researchers to present CUDA and discuss its advanced use for science and engineering domains. The morning session will introduce CUDA programming and the execution and memory models at its heart, motivate the use of CUDA with many brief examples from different HPC domains, and discuss fundamental algorithmic building blocks in CUDA. The afternoon will discuss advanced issues such as optimization and “tips & tricks”, and include real-world case studies from domain scientists using CUDA (VMD and NAMD Molecular Dynamics and Oil and Gas).

Overview: The goal of this workshop is to provide a forum for general-purpose purpose GPU programming environments and platforms, as well as discuss applications that have been able to harness the horsepower provided by these platforms. This year’s workshop is
particularly interested in imaging applications. Papers are being sought on many aspects of GPUs, including (but not limited to):

• GPU applications
• GPU software and operating systems
• GPU programming environments
• GPU power/efficiency
• GPU architectures
• GPU benchmarking/measurements

Paper Submissions: Authors should submit an 8 page paper in IEEE double-column style to gpgpu@ece.neu.edu.

Industry Participation: The workshop encourages participation by GPU manufacturers, software vendors, or companies which develop or market products used by the GPU community. Any company interested in participating in the workshop should contact the workshop organizer at gpgpu@ece.neu.edu.

Important Dates:
Paper submission: August 28, 2007
Author notification: September 7, 2007
Final paper: September 14, 2007

Copies of final papers will be made available at the workshop. In addition, selected papers will be invited to be part of a special issue of an ACM or IEEE journal or magazine.

On 4-5 August 2007, San Diego hosted the annual Graphics Hardware conference. GPGPU figured prominently in three papers:

• As transistors get smaller, their transient failure rates increase. Future architectures must adapt to address the resulting reliability problems. Jeremy Sheaffer presented a paper demonstrating a hardware-based redundancy approach to ensure reliability on GPGPU applications. (“A Hardware Redundancy and Recovery Mechanism for Reliable Scientific Computation on Graphics Processors”. Jeremy Sheaffer, University of Virginia; David Luebke, NVIDIA Research; Kevin Skadron, University of Virginia.)
• Magnus Strengert presented a generic, minimally intrusive, and application-transparent GLSL debugger that operates transparently to the application. In it, shader debugging is performed on a per-draw call level; it allows singlestepping and the inspection of arbitrary variable content. Linux code is available and Windows code is expected by the end of the year. (“A Hardware-Aware Debugger for the OpenGL Shading Language”. Magnus Strengert, Thomas Klein, and Thomas Ertl, University of Stuttgart.)
• One critical need for GPGPU developers is a library of general-purpose building blocks for GPU computation. Shubhabrata Sengupta presented a paper describing a GPU implementation of the “scan primitives” and their use in novel GPU implementations of quicksort, efficient sparse matrix-vector multiplication, and tridiagonal matrix systems. This paper won the Best Paper award and the authors are preparing an open-source release. (“Scan Primitives for GPU Computing”. Shubhabrata Sengupta, UC Davis; Mark Harris, NVIDIA Corporation; Yao Zhang, UC Davis; John D. Owens, UC Davis.)

All Graphics Hardware 2007 papers are available in the ACM digital library. In addition, the GH07 program page contains slides for all talks as well as two keynote talks (Chas. Boyd of the Microsoft DirectX team: “Mass Market Applications of Data-Parallel Computing” and Michael Jones, chief technologist of Google Earth: “GPUs for the true mass market”) and vendor talks from AMD and NVIDIA about their latest processors (AMD Radeon HD 2900 and NVIDIA’s Tesla).
