1. An array processing system interfacing with a host processor for performing I/O functions and a file memory, said array processing system comprising: data base buffer memory means having at least one data transfer channel connected to the file memory under control of the support processor for rapid transfer of information therethrough, said data base memory means receiving parallel processing jobs from the file memory and returning to the file memory the processed resultants of the jobs received, said parallel processing jobs including both programs for vector and scalar processing and related data; an array of parallel memory modules connected via a second data transfer channel to said data base memory means, each memory module in said array storing data from said data base memory means during processing by said array processing system; an array of parallel processor means, each processor means being programmable for independently processing data fetched approximately in parallel from individual memory modules, each processor means having indicator means for indicating when a future operation must be initiated in parallel with at least one other processor means for indicating when it is ready to begin said future operation; connection network means interposing said array of parallel memory modules and said array of parallel processor means, said connection network means providing a plurality of data communication paths between said array of parallel memory modules and said array of parallel processor means wherein each provided data communications path in said plurality thereof is provided to a requested individual memory module from a requesting individual processor means; and coordinator means connected to each processor means for monitoring each said indicator means for indicating when a future operation must be initiated in parallel with at least one other processor means and for inhibiting each processor means so indicating from initiating said future operation until each processor means so indicating is also indicating that it is ready to begin it's future operation.
