MCR
From coreboot
MCR is a large (11.2 TF) tightly coupled Linux cluster for use by the M&IC community. MCR has 1,152 nodes, each with two 2.4-GHz Pentium 4 Xeon processors and 4 GB of memory. MCR runs the LLNL CHAOS software environment, which incorporates the Red Hat Linux operating system. This system was integrated during summer 2002, entered science-run mode in late 2002, and was made generally available for production in October 2003.
