Abstract
We describe a web-based control system for invoking pipelined
processes on a large on-line archive of geostationary satellite imagery
through a World Wide Web browser interface. Our archive of GMS5
satellite data is stored on a combined RAID and tape silo system,
accessible from a cluster of ATM-connected DEC Alpha workstations
in Adelaide and Canberra. Our system makes use of parallel and
distributed computing software technologies, controlled using Common
Gateway Interface and Java code invoked through a WWW server. A
number of pipelined processes are scheduled and run on the distributed
system. We give some performance measurements for access times and
processing times for various parts of our system. We discuss the rapid
prototyping advantages and the constraints on functionality, scalability,
performance and security that arise from using such technology.
