OPTICAL HOLOGRAPHIC INTERCONNECTION NETWORKS FOR PARALLEL AND DISTRIBUTED PROCESSING

AN OPTICIAL HOLOGRAPHIC APPROACH IS USED TO RELIEVE THE BOTTLENECK AND COMPLEXITY OF INTERCONNECTION NETWORKS FOR LARGE-SCALE PARALLEL AND DISTRIBUTED MULTICOMPUTER ARCHITECTURES. THE OPTICAL HOLOGRAPHIC INTERCONNECTION NETWORK CONSTITUTES A VOLUME HOLOGRAM (OR A PLANAR HOLOGRAM)THAT CAN PERFORM EITHER REGULAR OR QUASI-REGULAR INTERCONNECTION OPERATIONS IN THREE-DIMENSIONAL SPACE (OR TWO-DIMENSIONAL PLANAR) STRUCTURES. SINCE MOST OF THE STATE-OF-THE-ART INTERCONNECTION PATTERNS FOR PARALLEL MULTICOMPUTER ARCHITECTURES ARE REGULAR OR QUASI-REGULAR, SEVERAL GRATINGS STORED ON THE HOLOGRAM CAN EVENTUALLY REDIRECT THE ENTIRE (OR PARTIAL) INPUT TO THE DESIRED LOCATIONS. THEREFORE, THE OPTICAL HOLOGRAPHIC INTERCONNECTION NETWORKS CAN BE PRACTICALLY REALIZED USING WELL-DEVELOPED HOLOGRAPHIC TECHNOLOGY AND LOW-COST OPTICAL ELEMENTS. ADDITIONAL ADVANTAGES OF HOLOGRAPHIC INTERCONNECTION NETWORKS ARE THE CAPABILITY OF MULTIPLEXING (EITHER ANGULAR OR WAVELENGTH). IN OTHER WORDS, THE STORAGE CAPACITY OF A HOLOGRAM WILL SUPPORT MULTIPLE MULTI-COMPUTER SYSTEMS WHOSE INTER-CONNECTION PATTERNS ARE DIFFERENT. IT IS BELEIVED THAT THE LARGE-SCALE COMMUNICATION PROBLEMS IN THE CURRENT AND FUTURE PARALLEL COMPUTER CAN BE SOLVED BY THE HOLOGRAPHIC OPTICAL OPERATIONS, GLOBAL INTERCONNECTIONS, SIMPLE FABRICATION, ANDFLEXIBLE DESIGN.
