  ARCHITECTURE AND APPLICATION:  THE PERFORMANCE OF THE
         NEC SX-4 ON THE NCAR BENCHMARK SUITE

In November 1994, the NEC Corporation announced the SX-4 
supercomputer.  It is the third in the SX series of 
supercomputers and is upward compatible from the SX-3R 
vector processor with enhancements for scalar processing, 
short vector processing, and parallel processing.  In 
this talk we describe the architecture of the SX-4 which 
has an 8.0 ns clock cycle and a peak performance of 2 
Gflops per processor.  We also describe the composition 
of the NCAR Benchmark Suite, designed to evaluate the 
computers for use on climate modeling applications.  
Additionally, we contrast this benchmark suite with other 
benchmarks.  Finally, we detail the scalability and per-
formance of the SX-4/32 relative to the NCAR Benchmark 
Suite. 

Steve Hammond is the head of Computational Science 
Section at National Center for Atmospheric Research 
(NCAR) at Boulder.  His research interests are in 
parallel computing, numerical linear algebra, graph 
partitioning and mapping.
