Analysis of the Component Architecture Overhead in Open MPI
Abstract. Component architectures provide a useful framework for developing an extensible and maintainable code base upon which largescale software projects can be built. Component methodologies have only recently been incorporated into applications by the High Performance Computing community, in part because of the perception that component architectures necessarily incur an unacceptable performance penalty. The Open MPI project is creating a new implementation of the Message Passing Interface standard, based on a custom component architecture – the Modular Component Architecture (MCA) – to enable straightforward customization of a high-performance MPI implementation. This paper reports on a detailed analysis of the performance overhead in Open MPI introduced by the MCA. We compare the MCA-based implementation of Open MPI with a modified version that bypasses the component infrastructure. The overhead of the MCA is shown to be low, on the order of 1%, for both latency and bandwid...
