Configuring computing nodes in a three-dimensional mesh topology

Abstract:

A computer-implemented method is provided for use with a reconfigurable computational device having a collection of computing nodes arranged in a mesh of N.times.M.times.Z topology, the computing nodes including computational hardware, wherein Z<N and Z<M, and wherein N and M are at least equal to 4. The method includes using the computational device to perform computations characterized by (i) an initial system I/O bandwidth and (ii) an initial system node-to-node latency; reconfiguring the device into a mesh of N'.times.M'.times.Z' topology, wherein at least two of N, M, and Z values are different from their corresponding N', M', and Z' values, and wherein N.times.M.times.Z is equal to N'.times.M'.times.Z'; and using the device to perform computations characterized by (i) a modified system I/O bandwidth and (ii) a modified system node-to-node latency.
