The Sloan Digital Sky Survey (SDSS) will image one quarter of the sky centered on the northern galactic cap and produce a 3-D map of galaxies and quasars found in the sample. An additional 225 deg2 southern survey will be imaged repeatedly on varying timescales. Here we discuss both archival searches in the SDSS catalog (such as SDSS J24602.54+011318.8) and active searches with the SDSS instruments (such as for GRB 010222) for GRB afterglows and other transient objects.

The Sloan Digital Sky Survey data has driven us to design the Terabyte Analysis Machine, a high-I/O compute cluster built on a cluster of commodity computers, a fiber channel network, and a large disk tower; on Linux, on a new cluster file system called GFS, and on the sophisticated SX database. Our initial implementation is a 7 dual processor nodes with 500 Gb of local disk and 730 Gb of global disk. We expect to use the TAM to search the first 1000 sq-degrees of the SDSS for clusters of galaxies. © 2001 American Institute of Physics. [ABSTRACT FROM AUTHOR]

The Sloan Digital Sky Survey is among the first of the new generation of large scale sky surveys that enabling the construction of revolutionary new cluster catalogs. I describe here some of the experiences of creating a SDSS cluster catalog, some of the computational challenges we encountered, and what we can expect in the near future. © 2001 American Institute of Physics.
