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.
