Cray Benchmarking Ideas 2003
WANTED: TEST PROGRAMS FOR A SUPERCOMPUTER
***Please send me programs that are computationally intensive.
(rlatimer@tjhsst.edu)
***We are looking for programs to strain the diodes of our
Cray SV1 supercomputer
Examples:
- calculatePi.c,
and calculatePiCray.c
(Cray version - same as workstation)
- calPiMPI.c
(Cray and workstation versions are the same)
- Description of PI
Calculation using the arctan series.
- PI Benchmarking
Results for the Cray and Workstations
- laplace-cache.c,
laplace-cacheCray.c
(Cray version - same as Workstation version)
- laplace-vector.c,
laplace-vectorCray.c
(Cray version - same as Workstation version)
- laplace-cache.f,
laplace-cacheCray.f
(Cray version - use "f90" to compile)
- laplace-vect.f,
laplace-vectCray.f
(Cray version - use "f90" to compile)
- Laplace Code
(Scalar) in Fortran,
Laplace
"vectorized" version (optimized for Cray)
- Laplace Benchmarking
Results for the Cray and Workstations
- Running programs on
the Cray SV1
- Compare the times of running programs on the Cray SV1 and on our regular computers
- Information on
Vector Architectures
- Features of the SV1 at OSC (Jim
Guiliani),
HTML slides and
Code
performance analysis: Vector Loop, Laplace Equation Solver,
Non-linear Wave Equation Solver
- Cray SV1
