 +During the scheduled power outage of December 28th, 2010, some benchmarks were performed on old and new clusters.  To read about the details of all that, view this [[cluster:91|page]].
 +
 +In short using linpack (More about [[http://en.wikipedia.org/wiki/LINPACK|Linpack on wikipedia]]) here are the results.  The results are dependent on the combination of total memory, total cores, and speed of processors.
 +
 +  * greentail's Voltaire infiniband switch is capable of just over 1,500 gigaflops or 1.5 teraflops.
 +  * petaltail/swallowtail's Cisco infiniband switch is capable of 325 gigaflops
 +  * petaltail/swallowtail's Force 10 ethernet switch is capable of 245 gigaflops
 +    * so the total is 570 gigaflops, but you'd never want to run across both switches simultaneously
 +  * sharptail's HP ProCurve ethernet switch is estimated at deleivering between 500-700 gigaflops
 +    * never got quite all the nodes working together, not sure why
