Hi,
where did you get these numbers?
If you really want to compare the latency of actual interconnects you should use the official performance results achieved in real environments using the driver api:
(values from homepages)
1. SCI (dolphinIcs) : 1.4 us
2. Quadrics: 1.7 us
3. Infiniband 4.5 us
4. Myrinet 6.3 us
MPI latency and bandwidth highly depend on the mpi library. I suggest to compare the mpich results.
I rated these interconnects. But I'm sorry, I only have a german version.
