Abstract
Techniques are described for providing mechanisms of data distribution to and collection of data from multiple memories in a data processing system. The system may suitably be a manifold array (ManArray) processing system employing an array of processing elements. Virtual to physical processing element (PE) identifier translation is employed in conjunction with a ManArray PE interconnection topology to support a variety of communication models, such as hypercube and such. Also, PE addressing nodes are based upon logically nested parameterized loops. Mechanisms for updating loop parameters, as well as exemplary instruction formats are also described.
