Not for Myrinet. Actually $2000 per node is the total cost 
(NIC/cable/port/software) for the high-end products (with L9/200 MHz), 
should be more like $1500 for low-end ones. Craig is spoiled, only buys 
the top stuff :-)

Dunno for QSW, but the NIC represent roughly 3/4 of the price per node 
for Myrinet. Sure, as the smallest switch has 8 ports (16 ports chassis 
and one blade with 8 fibers), It is not interesting for very small 
configurations, i.e less than 8 nodes, but I don't think it's Myricom's 

It's a common mistake to believe that switchless solutions are by 
definition cheaper.
