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.
| Name | Ndof | Description | SOL | MEM | SCR Disk | I/O Transferred | Comments |
|---|---|---|---|---|---|---|---|
| VLFDF | 135,702 | Propeller | 108 | 320 Mb | 3782 Mb | 33.5 Gb | Complex Solution |
| VLMMD | 155,849 | T6 Coup | 103 | 320 Mb | 4636 Mb | 210.8 Gb | 809 Modes |
| LGMST | 99,191 | Transmission Gear | 101 | 64 Mb | 556 Mb | 3.0 Gb | |
| LGAST | 55,521 | Engine | 101 | 40 Mb | 766 Mb | 5.3 Gb | |
| VLGST | 134,333 | T-Joint | 101 | 150 Mb | 585 Mb | 2.4 Gb |
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.
