The following results show the performance of the
ParaWise generated parallel RJET code on an SGI Origin
2000 (at SGI). The software is used to simulate vortex
dynamics and breakdown in turbulent jets using a
hybrid, high order compact finite difference scheme.
The serial RJET code was developed by M.White at the
Ohio Aerospace Institute (and was parallelised under
an evaluation project with Dr. R.Luczak, ASC and Dr.
Code information: 5900 lines of
source and 39 subroutines
Total Parallelization Time
: Approximately 3 hours.
User Time: Approximately 20 minutes.
