  abstract = {We discuss the results of a collaborative project on parallel
  processing of Synthetic Aperture Radar (SAR) data, carried out between the
  NASA/Jet Propulsion Laboratory (JPL), the California Institute of Technology
  (Caltech) and Intel Scalable Systems Division (SSD). Through this
  collaborative effort, we have successfully parallelized the most
  compute-intensive SAR correlator phase of the Spaceborne Shuttle Imaging
  Radar-C/X-Band SAR (SIR-C/X-SAR) code, for the Intel Paragon. We describe the
  data decomposition, the scalable high-performance I/O model, and the
  node-level optimizations which enable us to obtain efficient processing
  throughput. In particular, we point out an interesting double level of
  parallelization arising in the data decomposition which increases
  substantially our ability to support ``high volume'' SAR. Results are
  presented from this code running in parallel on the Intel Paragon. A
  representative set of SAR data, of size 800 Megabytes, which was collected by
  the SIR-C/X-SAR instrument aboard NASA's Space Shuttle in 15 seconds, is
  processed in 55 seconds on the Concurrent Supercomputing Consortium's Paragon
  XP/S 35+. This compares well with a time of 12 minutes for the current
  SIR-C/X-SAR processing system at JPL. For the first time, a commercial system
  can process SIR-C/X-SAR data at a rate which is approaching the rate at which
  the SIR-C/X-SAR instrument can collect the data. This work has successfully
  demonstrated the viability of the Intel Paragon supercomputer for processing
  ``high volume'' Synthetic Aperture Radar data in near real-time.},
