Parallel SAR processor using PVM on a Beowulf cluster
Michael Raymond Inggs, T.G. Bennett · 2002
Beowulf cluster computers (often called a "pile of PCs") have become common place, since they offer significant processing power at a fraction of the cost of custom, massively parallel machines. The processing needs of SAR naturally seem to point to a Beowulf cluster. However, as with all parallel computing, task granularity is a governing factor in the choice of compute node (processor, memory) and the interconnection (network technology and switch). This paper examines some of these issues in the design and testing of a SAR processor for a non real-time airborne radar. The system presented was constrained to fit to an existing, small Beowulf cluster.
