Parallel Prefix Sum Algorithm on Optoelectronic Biswapped Network Hyper Hexa-cell

By Ashish Gupta Bikash Kanti Sarkar

DOI:, Pub. Date: 8 Aug. 2018

The biswapped network hyper hexa-cell is recently reported optoelectronic network architecture for delivering excellent performance especially for mapping numerical problems which demands frequent routing and broadcasting. This network contains some important benefits such as smaller diameter, higher bisection width, and lower network’s total and optical cost as compared to counter-part OTIS hyper hexa-cell network. It is also advantageous as compared to the traditional biswapped network mesh containing smaller diameter and higher minimum node degree. In this paper, we present a parallel algorithm for mapping prefix sum of  data elements on a dh-dimensional biswapped network hyper hexa-cell of processors (assuming each processor contain single data element). It demands total  + 10 intra-cluster (electronic) and 3 inter-cluster (optical) moves.
