TITLE:
CUDA: Accelerating Science With Massively Parallel Computing
ABSTRACT:
Modern GPUs (graphics processing units) provide a level of massively
parallel computation that was once the preserve of supercomputers like
the MasPar and Connection Machine. NVIDIA's Tesla architecture GPUs
are a fully programmable, massively multithreaded chip with up to 240
cores, 30,720 threads and capable of performing up to a trillion
operations per second. The CUDA platform provides a scalable parallel
programming model consisting of minimal but expressive changes to the
familiar C/C++ language, allowing programmers to focus on parallel
algorithm rather than the mechanics of a new programming language.
Using this platform, researchers across science and engineering are
accelerating applications in their discipline by up to two orders of
magnitude.
In this talk, I will motivate GPU computing and explore the transition
it represents in massively parallel computing: from the domain of
supercomputers to that of commodity "manycore" hardware available to
all. I will also survey some of the results researchers have achieved
in actual science and engineering codes. Finally, I will discuss the
goals, implications, and key abstractions of the CUDA programming
model, and close with some comments on future directions for GPU
computing.

David Luebke joined NVIDIA Corporation in 2006 to help found NVIDIA
Research. Previously he spent eight years on the faculty of the
University of Virginia. He received his Ph.D. in Computer Science from
the University of North Carolina in 1998 under the supervision of Dr.
Frederick P. Brooks, Jr. Luebke's principal research interests are
general-purpose GPU computing and realistic real-time computer
graphics. At the University of Virginia he received both the National
Science Foundation CAREER award and the Department of Energy Early
Career Principal Investigator award, as well as the Test of Time award
ACM Symposium on Interactive 3D Graphics "Test of Time Award" in 2005
for the paper with the most impact from the early years of the
Symposium. Together with his colleagues Dr. Luebke has worked on
dozens of papers, articles, chapters, and patents; a short film in the
SIGGRAPH 2007 Electronic Theater; the book "Level of Detail for 3D
Graphics"; and the 2003 Virtual Monticello exhibit seen by over
110,000 visitors to the New Orleans Museum of Art.
