ORCS: An Oblivious Routing Congestion Simulator
(Feb 2009), 12 pages
This report describes the design of the ORCS simulator. The simulator can be used to perform InfiniBand congestion simulations to in order to assess the effective bisection bandwidth of a given InfiniBand network. It can also be used to simulate the influence of network noise to collective operations and arbitrary messaging patterns.
