Abstract
We present some software architecture ideas for a distributed control
and storage management environment, specifically for providing
high-level services across wide area networks of high-performance
computing resources. We describe the driving applications for our
system such as geographic information systems and digital libraries
and the particular design criteria they require. We discuss: scalable
architectural design through peer-to-peer protocols; the execution
paradigm, resource description, job scheduling and mapping; the
specification and interface management of high level services;
multiple networks for control and bulk data transfer; legacy
application support mechanisms; distributed data repository design,
data layout and compression support; user query support and cached
product support.
