This paper describes a novel, pipelined resource
management architecture for computational grids. The
design is based on two key realizations. One is that resource management involves a sequence of tasks that is
best handled by a pipeline. As shown in the paper, this
approach results, in a scalable architecture for decentralized scheduling. The other realization is that static aggregation of resources for improved scheduling is inadequate in wide-area computing environments because the
needs of users and jobs change with both, location and
time. The described architecture addresses this problem
by dynamically aggregating resources in a manner that
continuously optimizes system response. This is accomplished by way of an active yellow pages directory
that allows aggregation constraints to be (re)defined on
the fly. An initial prototype of the active yellow pages
service has been deployed in the PUNCH network computing environment. Experiences with the production
PUNCH system and preliminary results from controlled
experiments indicate that the active yellow pages service performs well.
