Hello,
Attached in MS Word and copied below is an NCSA Seminar we will be
broadcasting via Access Grid on Thursday, October 3, 2002 at 4-5pm central
using the NCSA system. I would like to have this listed on your
calendar. If you have any questions, please don't hesitate to contact me
at 217-244-0078 or via email.
thanks for your help,

Green Destiny: A 240-Node Compute Cluster in One Cubic Meter

Abstract
In this talk, Dr. Feng will present a new twist to the Beowulf cluster the
Bladed Beowulf. In contrast to traditional Beowulfs, Dr. Feng's Bladed
Beowulf, dubbed Green Destiny, uses Transmeta processors in order to keep
thermal power dissipation low and reliability and density high while still
achieving comparable performance to Intel- and AMD-based clusters when
their processors run at the same clock rate.
Although performance and price/performance have been (and will continue to
be) important metrics in high-performance computing, Dr. Feng believes that
the issues of efficiency, reliability, and availability will be the key
issues of this decade. Bigger and faster machines will not be good enough
anymore. Consequently, he proposes a new performance metric, Total
Price/Performance Ratio (ToPPeR), to evaluate high-performance computing
systems. However, due to the hidden and institution-specific costs in the
ToPPeR metric, two alternative (but more concrete) performance metrics that
are related to efficiency, reliability, and availability are also
proposed: performance/power ratio ("power efficiency") and
performance/space ratio ("space efficiency"). Dr. Feng will then present
empirical data for the aforementioned metrics over a variety of computing
platforms using a cosmology code and a bioinformatics code.

Biography
Dr. Feng received a B.S. degree in computer engineering and a B.S. (Honors)
degree in music from Penn State University in 1988; an M.S. degree in
computer engineering from Penn State University in 1990; and a Ph.D. degree
in computer science from the University of Illinois at Urbana-Champaign in
1996.
He is currently a technical staff member and team leader of RADIANT
(Research & Development in Advanced Network Technology at
http://www.lanl.gov/radiant) at Los Alamos National Laboratory and an
adjunct assistant professor at the Ohio State University. He is a fellow
of the Los Alamos Computer Science Institute and the founder and director
of the Advanced Summer Curriculum for Emerging Network Technologies
(ASCENT). Before joining LANL in 1998, Dr. Feng had previous professional
stints at Purdue University, University of Illinois, NASA Ames Research
Center, and IBM T.J. Watson Research Center.
