About the Cray SV1e
This is a reasonably traditional general purpose vector supercomputer.
The Cray SV1e, installed in December 2001, consists of 32 processors
connected via a fast crossbar switch to 1024 memory banks comprising
a total of 32 Gbyte shared memory.
Each processor with a capacity of 2 Gflop/s has vector capabilities,
so the peak performance of the Cray SV1e is 64 Gflops. The Cray
SV1e is configured with a disk space of 250 Gbyte.
The Cray SV1e is a computer designed to apply arithmetic operations
to long vectors or arrays. Most vector processors rely heavily on
pipelining to achieve high performance.
About HPC & V
High Performance Computing (HPC) as well as Visualisation and Virtual
Reality are two of the areas of the RuG-ICT strategy (2000-2004)
that receive a new impulse in order to continue a tradition to provide
Groningen scientists with state-of-the-art facilities needed for
excellence in computational science.
It is the mission of the Centre for High Performance Computing
and Visualisation (HPC & V) is to support and stimulate the
use of facilities for these two areas of the RuG-ICT strategy. These
facilities should benefit all scientific communities within the
University of Groningen.
- In order to realise the HPC-facilities, a Linux Alpha cluster
having a peak performance of 22 Gflops was put in production in
1999 as a supplement to the Cray.
- In 2001 a Linux cluster with 128 processors, having a peak
performance of 0.22 Tflops, was added.
- In December 2001 the Cray G932 was upgraded to a CRAY SV1e.
The full HPC-facility will be expanded and will have a peak performance
of 0.5 Tflops in 2004.
