MSC/NASTRAN V70.5 Through Put Performance
Elapsed time is becoming more critical for many clients. The following
chart shows accumulated wall time for five MSC/NASTRAN runs. The runs
were submitted on several hardware platforms. VLFDF and VLMMD were submitted
batch, then LGMST, LGAST, and VLGST were submitted sequentially in the
foreground.
Below is a summary of the test problems. Several models are nonpropriatary
and may be viewed by clicking on the model name.

Notes:
- lmgst, lgast, and vlgst were run sequentially, while vlfdf and vlmmd
were running simultaneously.
- Cray runs were NOT on dedicated systems.
- HP J5000 runs were on a system with only two CPUs.
