ABSTRACT
This paper describes the design and implementation of
SWORD, a scalable resource discovery service for wide-area
distributed systems. SWORD locates a set of machines
matching user-specified constraints on both static and dy-
namic node characteristics, including both single-node and
inter-node characteristics. We explore a range of system ar-
chitectures to determine the appropriate tradeoffs for build-
ing a scalable, highly-available, and efficient resource discov-
ery infrastructure. We describe: i) techniques for efficient
