>> Myrinet maybe cheap but in low reliability.

That has not been our experience.  We have been running Myrinet (a couple of different generations) for over six years on about 80 hosts, in a facility with poor environmentals (power, cooling, humidity), and have lost only one switch port and one NIC in all that time.  That seems about as reliable as anything you're likely to find.
