Abstract
In this paper we present a middleware infrastructure, called DataCutter, that en-
ables processing of scientific datasets stored in archival storage systems across a wide-
area network. DataCutter provides support for subsetting of datasets through multi-
dimensional range queries, and application specific aggregation on scientific datasets
stored in an archival storage system. We also present experimental results from a pro-
