Advanced Computing Center (TACC) at The University
of Texas at Austin, a resource partner within the NPACI
Grid, has begun installation of a terascale high-performance
computing cluster. The cluster, to be named Lonestar,
will help advance innovative research in computational
science, engineering, and technology.
Lonestar has 300 Dell
PowerEdge servers, each with two 3.06 GHz Intel Xeon
processors, linked to one another by a Myrinet 2000
network switch. The initial configuration has 636 gigabytes
total memory and a theoretical peak performance of 3.67
teraflops. TACC plans to expand the system to more than
800 processors before the end of 2003 and more than
1,000 processors within the first year of operation.
Cray Inc. of Seattle, WA will integrate and deploy
the system using a version of the NPACI Rocks cluster
management software call Cray/Rx
" Lonestar will provide tremendous
simulation capability for researchers trying to solve
challenging research problems, and we expect the system
to grow rapidly and continuously. It will rank among
the most powerful terascale clusters in the world for
academic research," said John R. (Jay) Boisseau,
director of TACC. Half of the CPU hours will be allocable
through the PACI process,
and Boisseau expects the system to be available for
early users on October 1.
The acquisition of Lonestar is part
of a recent $38 million investment by the University
of Texas, a private foundation, and several industrial
partners, including Cray and Dell. This investment also
created the Institute for Computational Engineering and
Sciences (ICES), a new center for interdisciplinary
research and graduate study in the computational sciences.
"Lonestar will bring extraordinary computing power
to ICES researchers and enable our graduate students
to get first-hand experience in very large scale parallel
computing with broad applications to science and engineering,"
said Dr. J. Tinsley Oden, director of ICES and leader
of NPACI's Engineering thrust area. --Merry Maisel
