It is composed of twenty SGI Altix 3000 nodes each of which have 512 Intel Itanium 2 Processor s bringing the total number of processors to 10,240. It was named in honour of the crew of the Space Shuttle Columbia . The SGI Altix platform was selected due to a positive experience with Kalpana , a single Altix 512-CPU system operated by NASA Ames which was integrated into the Columbia supercomputer system. The computers are connected together with a Voltaire InfiniBand ISR 9288 288 port Switch with transfer speeds of up to 10 Gigabit s (or 10240 Megabyte s) per Second , 10 gigabit Ethernet and multiple 1 gigabit Ethernet nodes.
