MSC.Nastran V70.5.1 Academic Performance
Data
The data provided is based on limited testing and MSC makes no warranties as to
its accuracy or completeness.
This page contains a bar graph of
Cumulative CPU times for a 100,000 DOF static and normal modes cylinder (2-D
elements) and for a 40,000 DOF solid (3-D elements) for several systems using
MSC.Nastran V70.5.1.
Caveats/Limitations are listed below:
- The operating system load varied
from one computer to another.
- This bar graph is for a cylinder
with 2-D elements (SOL 101 and SOL 103) and a cube with 3-D elements (SOL
101). Results may vary a lot based on SOL, DOF, element type, and many other
factors.
- The Sun SuperSparc and IBM RS6000/340
only had 64Mb of memory on their systems. This limitation might have slowed
down the 40K statics Cube model.
- These analyses contain a lot
of output requests.
Below is a summary of the test problems.

Partial Interpretation of Results:
- Although the HP_K250 is slower
than the HP_K460, it appears faster on these charts because the HP_K250 is
running HPUX 11.0 and the HP_460 is running HPUX 10.20.
- These models are realatively
small to be run on SuperCompters (such as CRAY and NEC). Those systems show
much better performance with larger (> 1,0000,000 DOF) analyses. (For V70.5,
results for larger models will be given.)
