Study on SAR data parallel processing using computing cluster

Abstract

This paper proposes a working framework for SAR data parallel processing using computing cluster, which includes a master node and a number of computing nodes. This framework supports coarse-grained data processing and the master node controls the whole workflow and the data distribution strategy, by which the coarse-grained data are distributed to the computing nodes in order and the computing nodes are responsible for data processing. The experiment of the real data processing demonstrates that the efficiency of the computing cluster can be improved significantly under this framework.
