Clemson Regional Data Center
The Clemson Regional Data Center is a testbed for research in computer
systems that support remote sensing. In addition to the traditional image
processing that forms the heart of these systems, remote sensing includes
processing of satellite telemetry including instrument calibration, georegistration,
and image formatting; database design and management; and numerical simulation
of Earth systems. Shown above is the computer equipment currently in operation
at the Clemson RDC. On the left is a GOES ingest system that receives geosynchronous
weather data on a continuous basis. This system generates about 1GB of
raw data an hour. In the middle is our database management system that
indexes all of the data stored in our mass storage system. This system
can also be used for processing the data. On the right is the mass storage
and image processing system including 36GB of disk storage and 140GB of
near-line tape storage. Click here for a summary

The Clemson RDC was formed through a Memorandum of Understanding with
Goddard Space Flight Center
Code 935..
The Clemson Beowulf Cluster
The Clemson Beowulf cluster is also part of the Regional Data Center.
We are working to parallelize key RDC applications for the Beowulf
architecture. Our work on parallel file systems is central to this
effort. This system consists of 16 150MHz Pentium processors with 64MB
of RAM and 2GB of disk each, an additional processor used as the system
host, a switched full-duplex 100Mbps fast ethernet network, and an additional
100Mbps fast ethernet network.

for Excellence in Space Data Information Systems (CESDIS).
