Conclusions

We have seen that while there is a substantial difference of performance between the Myrinet 2 and Myrinet 2000 boards, there is no significant difference in performance on the different platforms we tested using the Myrinet 2000 boards.

We have also seen that there is no significant minimum latency difference (the one of a minimum length message) between the two Myrinet generations because of the overhead of the PCI bus.
