Abstract

The event model of the functional language CML (concurrent meta language) is used to capture concurrency, which normally remains unexploited within conventional parallel geometric harnesses running on (virtual) arrays of processors. This complexity is hidden from the application programmer, who merely supplies conventional geometric sequential code which is automatically executed in parallel. An example of a low-level image filtering operation is used, to show how execution efficiency can be maintained in spite of the communication delays and indeterminacies encountered in real networks.
