Performance Architecture within ICENI

Abstract

Abstract. This paper describes the architecture built into the Imperial College e-Science Infrastruc-ture (ICENI) for handling performance meta-data. The architecture provides a means to gathering per-formance information, processing this information to populate the performance store, and to use this performance information to aid in the selection of resources and component implementations. The Per-formance Framework is developed in a “pluggable ” manner allowing alternate implementations of the three main features to be used. Performance Stores may be either data stores or based on analytical models. 1
