Design and Implementation of a High-Performance CCA Event Service
Event services based on publish-subscribe architectures are well established components of distributed computing applications. Recently, an event service has been proposed as part of the Common Component Architecture (CCA) for high-performance computing applications. In this paper we describe our implementation, experimental evaluation, and initial experience with a high performance CCA event service that exploits efficient communications mechanisms commonly used on high-performance computing (HPC) platforms. We describe the CCA event service model, and discuss briefly the possible implementation strategies of that model. We then present the design and implementation of the event service using the Aggregate Remote Memory Copy Interface (ARMCI) as an underlying communication layer for this mechanism. Two alternative implementations are presented and evaluated on a Cray XD-1 platform. The performance results demonstrate that event delivery latencies are low and that the event service is able to achieve high throughput levels. Finally, we describe the use of the event service in an application for high-speed processing of data from a mass spectrometer, and conclude by discussing some possible extensions to the event service for other HPC applications.
