NVIDIA Powers Titan, World's Fastest Supercomputer For Open
Scientific Research 
Oak Ridge National Lab's 20+ Petaflops System -- Powered by
18,000-Plus NVIDIA Tesla K20 GPUs -- Paves Path to Efficient,
Affordable Exascale Computing 
SANTA CLARA, CA -- (Marketwire) -- 10/29/12 --   Titan, the world's
fastest open-science supercomputer,(1) was completed this month at
Oak Ridge National Laboratory in Tennessee, opening new windows of
opportunity into the exploration of some of the world's toughest
scientific challenges.  
Titan's peak performance is more than 20 petaflops -- or 20 million
billion floating-point operations per second -- about 90 percent of
which comes from 18,688 NVIDIA(R) Tesla(R) K20 GPU accelerators.
These are based on the NVIDIA Kepler(TM) architecture, the fastest,
most efficient, highest-performance computing architecture ever
Researchers use ever faster supercomputers to accelerate the pace of
discovery and innovation across a range of scientific fields of
inquiry -- from developing more efficient engines and higher
capacity, lighter weight batteries, to studying climate change and
finding cures for disease. Titan is a milestone on the path to
exascale computing, which targets building a 1,000 petaflops
Titan is operated by Oak Ridge National Laboratory, part of the U.S.
Department of Energy's network of research labs, as an open-science
system. This means it is available to researchers from academia,
government laboratories, and a broad range of industries who will use
Titan to model physical and biological phenomena and seek
breakthroughs faster than possible by experimentation alone. 
Supported by the energy efficiency and cost-effectiveness of the
Tesla K20 GPU, Titan is more than 10 times faster and five times more
energy efficient than its predecessor, the 2.3-petaflops(2) Jaguar
system, while occupying the same floor space. Had Oak Ridge upgraded
Jaguar by simply expanding its CPU-based architecture, the system
would be more than four times its current size and consume more than
30 megawatts of power.(3)  
"Basing Titan on Tesla GPUs allows Oak Ridge to run phenomenally
complex applications at scale, and validates the use of accelerated
computing to address our most pressing scientific problems," said
Scott, chief technology officer of the GPU Accelerated
Computing business at NVIDIA. "You simply can't get these levels of
performance, power- and cost-efficiency with conventional CPU-based
architectures. Accelerated computing is the best and most realistic
approach to enable exascale performance levels within the next
Titan development began three years ago with Oak Ridge's decision to
upgrade Jaguar, the previous open science system leader and a former
world No. 1 most powerful supercomputer. The upgrade includes the
Tesla K20 GPU accelerators, a replacement of the compute modules to
convert the system's 200 cabinets to a Cray XK7 supercomputer, and
710 terabytes of memory. 
"Science and technology have always been our primary goal, and Titan
is a groundbreaking tool that will allow researchers worldwide to
leverage GPU-accelerated computing to make unparalleled
breakthroughs," said Jeff Nichols, associate laboratory director for
computing and computational sciences at Oak Ridge National
Laboratory. "The new Tesla GPU accelerators offer the performance and
energy efficiency that enable Titan to scale to unprecedented
performance levels without consuming the energy equivalent of a small
About NVIDIA Tesla GPUs 
 NVIDIA Tesla GPUs are massively parallel
accelerators based on the NVIDIA CUDA(R) parallel computing platform
and programming model. Tesla GPUs are designed from the ground up for
power-efficient, high performance computing, computational science
and supercomputing, delivering dramatically higher application
acceleration for a range of scientific and commercial applications
than a CPU-only approach.

 NVIDIA (NASDAQ: NVDA) awakened the world to computer
graphics when it invented the GPU in 1999. Today, its processors
power a broad range of products from smartphones to supercomputers.
NVIDIA's mobile processors are used in cell phones, tablets and auto
infotainment systems. PC gamers rely on GPUs to enjoy spectacularly
immersive worlds. Professionals use them to create 3D graphics and
visual effects in movies and to design everything from golf clubs to
jumbo jets. And researchers utilize GPUs to advance the frontiers of
science with high performance computing. The company has more than
5,000 patents issued, allowed or filed, including ones covering ideas
essential to modern computing. For more information, see
