EVENT-DRIVEN COMPUTATION

An apparatus for high-performance parallel computation, includes plural computation nodes, each having dispatch units, memories in communication with the dispatch units, and processors, each of which is in communication with the memories and the dispatch units. Each dispatch unit is configured to recognize, as ready for execution, one or more computational tasks that have become ready for execution as a result of counted remote writes into the memories. Each of the dispatch units is configured to receive a dispatch request from a processor and to determine whether there exist one or more computational tasks that are both ready and available for execution by the processor.
