Abstract
We give an efficient shortest path algorithm on a mesh-connected proce ssor array for n x n banded matrices with bandwidth b. We use a [b/2xb /2] semisystolic processor array. The input data is supplied to the pr ocessor array from the host computer. The output from the processor ar ray can be also supplied to itself through the host computer. This alg orithm computes all pair shortest distances within the band in 7n-4[b/ 2]-1 steps.
