um, that just does away with the expensive infiniband switch in favor of 
an infiniband 'loop' architecture (eg, each host still uses an 
infiniband adapter), and virtualizes the switch.

this is simply a cost reducing measure in building conventional HP 
clustering where infiniband is often used for interprocess message 
passing because of its high performance and low latency.

you still need to program for a message passing environment and break 
your workload down into small chunks that can run independently
