Abstract

In this paper we describe the Panel of Experts cloud pattern and give examples of its use. The Panel of Experts pattern can be applied when a range of algorithms "compete" to provide the best solution to a problem. It can therefore be viewed as the dual of map-reduce [2] as it applies a set of functions to one data item, whereas map-reduce applies one function to a set of data items. The pattern has been evaluated through a large chemical informatics application which can take days to run on tens of cloud nodes.
