station at the South Pole, to be completed by 2005. In response to those reports, NSF requested appropriations to fund the SPSM. The station was designed to house 100 persons but with an infrastructure capable of supporting 150.

MREFC funding for the SPSM began in FY 1998 with an appropriation of $24.9 million [9]. The NSB approved expansion of the 110-person station concept to 150 in 2002. Construction of the tower linking the elevated structure to the new SPSE facilities began in FY 2000 [8]. Adverse weather conditions have slowed the delivery of construction materials and resulted in a shift in estimated completion from 2005 to 2007.

In FY 2000, NSF funded a Terascale Computing System (TCS) [1], the first NSF terascale system to be deployed by the NSF terascale computing systems activity. Based at the Pittsburgh Supercomputing Center (PSC), the TCS has a peak performance of 6 teraflops. When it was dedicated in October 2001, it was the second-most powerful computer in the world and the fastest one available for civilian research. The TCS employs 3,000 Compaq Alpha processors organized into 750 four-processor nodes. Aside from providing unprecedented computational speed, the TCS features 3.0 terabytes of total memory, 40 terabytes of primary storage, and 300 terabytes of disk and tape storage.

In FY 2001, NSF funded the Distributed Terascale Facility (DTF) [2], a geographically distributed, grid-enabled terascale computing system developed at four institutions: the National Center for Supercomputing Applications (NCSA), the San Diego Supercomputer Center (SDSC), Argonne
