7. SM050701-1640 Advanced Optics & Energy Technology Center Advanced Mirror Technology Small Business Innovative Research Sandy Montgomery/SD71 Plan: Purchase a Beowulf computer cluster and associated Linux software. Utilize the Beowulf in conjunction with optical test beds to develop the use of cluster computing for segmented mirror control. software for astronomy and wave front control, and application program - distributed computing (e.g. Fortran 99). Beowulf Background technology of clustering Linux computers to form a parallel, virtual supercomputer. one server node with client nodes connected together via Ethernet or some other network. no custom components; mass-market commodity hardware PC capable of running Linux, Ethernet adapters switches. Intiated in 1994 NASA High Performance Computing and Communications program Earth and space sciences project at the Goddard Space Flight Center. In October of 1996 Gigaflops sustained performance on a space science application for cost under $50K. MSFC CDDF Marshall Optical Control Cluster Computer (MOC 3 )
