Does anyone have any ideas?? I have just two boxes and a single switch.

What are you seeing? Do GM tests run at expected rates, e.g. latency less than 20usec and bandwidth near 100MB assuming your host bus is good enough? Are there other cards sitting on the same IRQ as the myrinet card? What version of GM, Myrinet hardware, type of host and OS are you using?
