Intial Pallas performance with Myrinet on a 860 & E7500

[alex at compusys.co.uk]

For your information, please look at the following performance
measurements for the 'C' class Myrinet2000 cards.

Details of the two machines (optimisation level: -fast & PGI):

- 2.4.17 kernel
- mpich-1.2.1..7b
- gm-1.5.1
- measurement performed between machines

860 Supermicro DCE:
- Dual P4 2 GHz
- C class Myrinet2000

The new E75000 Supermicro DDR : 
- Dual P4 1.8GHz 
- C class Myrinet2000, using PCI-X slot


Notice the results for E75000 Sendrecv:

4194304 --> 290.29Mbytes/s

That is more than the serverworks LE chipset.
