DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Data flow rates from astronomical surveys are growing rapidly, leading to enormous collections of raw pixel data. Simultaneously, this data is becoming freely available to the public. Although large astronomy surveys are typically funded to archive data, they are generally unable to fund collocated computing facilities that can process this data for all users. Therefore, a critical need is support for “computing at a distance.” The Large Synoptic Survey Telescope (LSST) Data Management System (DMS) provides such a cyber infrastructure. The DMS processes incoming images, produces transient alerts, archives over 50 petabytes of exposures, creates and archives an annual data release including catalogs of trillions of detected sources and billions of astronomical objects, makes LSST data available without a proprietary period, and facilitates analysis and production of user-defined data products with supercomputing resources. This paper discusses DMS distributed processing and data, with an emphasis on cyber infrastructure requirements and architecture.
