Worked from (11/86-end of project): Investigating the efficiency of the Hypercube architecture in Real-Time SAR data processing (``SAR Hypercube Project''). Non traditional FFT algorithms, such as the Prime Factor, have been coded to run on the nCUBE, iPSC, and Mark IIIfp hypercubes. The optimal decomposition, on a specific hypercube system, of a complete software package for digital SAR data processing has been determined. This package has been implemented in the sequential version on a VAX-780 at IESI/CNR (Bari-Italy) and has been tested on digital raw data obtained by JPL (SIR-B space Shuttle mission). Now works on: High Performance Distributed Computing (porting of several applications under PVM and Net-EXPRESS. Parallel compilers, such as HPF, will also be tested). A joint project with CCSF is in progress.

Peter Gorham
Project Manager
University of Hawaii at Manoa
Honolulu, Hawaii 96822
Worked from (1987-end of project): My work with P came about through Tom Prince's involvement with the project. Tom hired me as a postdoc in 1987 and I arrived in February of that year. Tom was beginning a collaboration with Shri Kulkarni of the Caltech Astronomy Department in two areas: first, a program to develop code for bispectral anlaysis of astronomical speckle interferograms taken with the Hale telescope; and second, a search for new radio pulsars using the Arecibo Observatory's transit telescope. In both cases, the telescopes involved were among the largest of their class and the data sets to be produced could only be managed with a supercomputer. Also in both cases, the data analysis lent itself very well to parallel processing techniques.

Both programs were very successful and Tom and I had the pleasure of seeing two graduate students complete their PhD requirements in each of the research areas (Stuart Anderson, pulsars; and Andrea Ghez, infrared speckle interferometry). Something of order a dozen research papers came out of this effort before I left for my present position in July of 1991, and a steady stream of results have come out since. Now works on: The Deep Underwater Muon and Neutrino Detector (DUMAND) project. This project is developing a large, deep ocean Cherenkov detector which will be sensitive to high energy neutrino interactions and will have the capability to produce images of the sky in the ``light'' of neutrinos, with angular resolution of order 1 degree. The motivation behind such research arises from current belief that emission of high energy neutrinos may be a dominant process by which active galactic nuclei and QSOs release energy into their galactic environment. Detection of such neutrinos would provide unique information about the central engine of such galaxies.
