Abstract

We present new optimal systolic algorithms for the transitive closure problem on ring and linear array of processors. The data dependency of the Warshal-Floyd algorithm is exploited to obtain highly pipelined parallel algorithms. One of the algorithms is asymptotically seven times cost-effective than the existing algorithms for computing transitive closure problems. We introduce a new expository device, called the RCT diagram, that depicts simultaneous flow of data and computation for parallel algorithms.
