Comparison of Infininand vs Gigabit Ethernet (GigE)

The great debate between Infiniband vs GigE has been ongoing and accelerated by arrival of 10GigE.These are some studies that compare the two protocols. While one is sockets based and the other is qpairs based, these high performance computation-heavy benchmarks stress test for latency, and bandwidth analysis. The results are surprisingly indicative of the type of workload that is running using each interconnect technology.
