Interconnect Description: QLogic InfiniBand HCAs and switches

Hardware
Vendor:	QLogic
Model:	InfiniPath adapters and Silverstorm switches
Switch Model:	QLogic SilverStorm 9080 Fabric Director (InfiniBand switch)
Number of Switches:	1
Number of Ports:	96
Data Rate:	InfiniBand 4x SDR and InfiniBand 4x DDR
Firmware:	3.4.0.1.3
Topology:	Full Bisectional Bandwidth, Fat-Tree, Max 3 swith-chip hops.
Primary Use:	MPI traffic

General Notes

The 64 nodes used are from one CU (Computational Unit, 65 nodes)
of the 9 CUs in the Darwin cluster. Jobs within one CU
use one SilverStorm 9080 switch.
The data rate between InifniPath HCAs and SilverStorm switches
is SDR. However, DDR is used for inter-switch links.
