Abstract : The objective of the program is to develop a Memory Distribution Network (MDM) for parallel access to secondary storage (devices) for high performance computing. The secondary storage was a large page oriented memory. It was to be connected to a smaller array of electronic processors for information retrieval. We have designed and constructed a novel reconfigurable interconnection scheme that allows a 4x4 arrays of 32x32 bits page oriented optical memory be parallel accessed with five different interconnection topologies using wavelength tuning. We have also designed, fabricated and tested the MOSIS chips that would process pages of 32x32 bits information received from the large memory before transferring the processed information to the smaller array of electronic processors. The system was capable of operating at 10 MHz with a memory retrieval throughput of 10(4) Mbits/sec. We have also demonstrated the application of parallel database search on the MDN system.
