   SOMERS, N.Y.--(BUSINESS WIRE)--May 2, 1994--IBM announced today that the most powerful 
IBM POWERparallel system(a) yet shipped is being  installed at the Maui High Performance 
Computing Center on Maui,  Hawaii.     Announced just last month, the 80-node SP2(a), a 
RISC-based UNIX(a)  parallel processing computer, is the initialinstallation of a machine  that the 
Center plans to scale to 400 processors later this year.  The  400-node system will be capable of 
delivering up to 100 billion  calculations per second, making it one of the most powerful scalable, 
 parallel computers in the world.  
   The IBM POWERparallel System SP2(a) is a price/performance leader  based on its 
outstanding performance on the NAS benchmark suite, on  which it dramatically outperformed the 
established competition(d).  Based on the NAS benchmarks, the POWERparallel SP2 has up to 
twice the  price/performance of the Cray T3D(c).  The NAS benchmark suite, which  is comprised 
of both pseudo-application and kernel benchmarks, was run  on 16 nodes and 64 nodes of the 
80-node system being installed at the  Maui Center.  
   The SP2 wide node has a LINPACK DP (Double Precision) performance  of 130.4 MFLOPS and 
a SPEC--fp92 rating of 242.4.  This is over twice  the performance of SP1 nodes.  
   "We have been exceptionally pleased with the performance and ease  of use of our SP1," said 
Dr. Frank Gilfeather, of the University of New  Mexico who, along with Drs. Brian T. Smith and 
John Sobolewski, are  responsible for establishing and managing the Maui High Performance  
Computing Center.  "We are excited about having the new SP2 here. The Center's users, already 
impressed with the SP1, are looking forward  to putting the system through its paces as we 
analyze satellite data,  run various chemistry and environmental modeling programs and explore 
 new parallel applications.   
   "Demand to use the POWERparallel machines is far outstripping our  expectations," Dr. 
Gilfeather continued.  "Of critical acclaim is the  ease of porting software applications.  Veteran 
supercomputer users are  excited about porting more applications to the SP2 and the Center."  
   The NAS benchmark suite will continue to be run on Maui's system as  nodes are added.  The 
80-node system has a peak performance of 21  gigaFLOPS (billions of calculations per second), 
and when it grows to  400 nodes, that peak performance will be over 100 gigaFLOPS.  Maui's  
Center will be officially open for business later this year, but early  users are already 
successfully using the Center's current SP1 for parallel  work.  
   "The benchmark results reported today on this machine prove that it  is one of the best 
systems in the world -- both in terms of sheer speed  and processor capability as well as 
price/performance," said Irving  Wladawsky-Berger, general manager of IBM POWER Parallel 
Systems.  "We  will continue to work closely with the directors of the Maui Center to  push the 
performance limits of the system as it grows to 400 nodes."  
   Benchmark Results  
   In laboratory tests, the POWERparallel SP2 16-node system exceeded  the performance of a 
64-node Cray T3D on a majority of the NAS  benchmark tests(d). The 16-node system also 
performed well against  the 64-node version of the Intel Paragon.  The 16-node SP2 exceeded 
the  performance of Kendall Square Research's KSR2 32-node system as well.  
   In tests, the 64-node SP2 system outperformed a 256-node T3D on all  but one pseudo 
application benchmark for which numbers are available  and surpassed all other competitors' 
high-end node configurations.  
   The 16-node and 64-node POWERparallel systems tested were  configured differently.  The 
16-node machine had 128 megabytes (MB) of  RAM per node and one gigabyte (GB) of disk per 
node.  The 64-node  system had 64 MB of RAM per node and one GB of disk per node.  
   The nodes in the systems tested were wide nodes, which have seven  slots for I/O and network 
attachments, and can accomodate up to eight  GB of internal disk storage and up to two GB of 
memory per node. -0- NAS SIMULATED CFD APPLICATION BENCHMARKS (CLASS A & CLASS

   The NAS benchmark was developed through the Numerical Aerodynamic  Simulation Program 
at the NASA Ames Research Center.  The NAS Program  is a large scale effort to advance the 
state of computational  aerodynamics.  The NAS Benchmark is a suite of benchmarks which is  
comprised of five kernel benchmarks and three simulated application  benchmarks.  This suite 
mimics the computation and data movement  characteristics of large-scale computational fluid 
dynamics (CFD)  applications.  Maui High Performance Computing Center  
   The Maui High Performance Computing Center was established through  a cooperative 
agreement between the Air Force's Phillips Laboratory in  Albuquerque, N.M., and the University 
of New Mexico.  The University of  New Mexico consortia, which includes the Cornell Theory 
Center,  Carnegie Mellon University, Environmental Research Institute of  Michigan, Numerical 
Algorithms Group and SETS Technology, Inc., was  selected last year to establish this 
Department of Defense resource  through a competitive bid process.  
   The Maui Center has been recently established as a large,  comprehensive supercomputer 
center.  It is unique in that it is remote  from a large base of scientific and engineering users.  
Thus the  performance of the computing environment will be tested under unique  circumstances, 
especially in the area of long-distance remote support.  
   The Center supports the U.S. Department of Defense's general  scientific computing needs as 
well as those of the scientific computing  community at large.  
   The Maui Center will benefit educational institutions, industry and  government agencies.  It is 
also intended to foster technology exchange  with U.S. industry, stimulate economic 
development and establish  educational programs in high-performance computing.  
   World Class Systems  
   IBM's POWER Parallel Systems business unit produces world-class  scalable, parallel 
information systems for commercial and  scientific/technical customers. 
   The IBM Scalable POWERparallel Systems 9076 SP2(a) features design  and performance 
leadership, offers exceptional reliability and  versatility, and delivers high performance

Report  RNR-93-016, October 27, 1993."     Prices provided by vendors include any associated 
software costs  (operating systems, compilers, scientific libraries) as required to run  the

 Prices are as of March  1994; some prices came from previous reports.     The Cray T3D price 
does not include the Cray front end machine.  (d)  Performance measurements for the IBM 
POWERparallel system are the  result of tests done in a laboratory environment at IBM Kingston 
using  Message Passing Library (MPL)/p.
 While these values should be  indicative of machine performance, no warranties or guarantees 
are  stated or implied by IBM.  These measurements are offered only as an  indicator of 
performance.     The NAS benchmark suite is a commonly used indicator of parallel  computer 
performance that has been developed through the Numerical  Aerodynamic Simulation (NAS) 
program at NASA's Ames Research Center.   The benchmark suite is comprised of five parallel 
kernel benchmarks and  three simulated computational fluid dynamics application benchmarks. 
   The LINPACK benchmark suite compares the performance of different  computers in solving 
dense systems of linear equations.  LINPACK  routines are compiled on a vendor's own 
FORTRAN compiler in an effort  to approximate what a typical user would experience.  The 
LINPACK  Double Precision benchmark measures a system's double precision  floating-point 
performance.  The LINPACK HPC benchmark provides a way  to compare masssively-parallel 
computers.  Dr. Jack Dongarra at the  University of Tennessee (and Oak Ridge National 
Laboratory) oversees  the administration of the LINPACK benchmark.
