A uniform MPI user experience with MPI-Start

AuthorsFernández-del-Castillo, Enol
Issue DateApr-2011
CitationEGI User Form (2011)
AbstractThe current middleware stacks provide a basic level of support for the Message Passing Interface (MPI) programming paradigm. Users face a complex and heterogeneous environment where too many low level details have to be specified to execute even the simplest parallel jobs. EMI is developing MPI-Start, a tool that provides an interoperable MPI execution framework across the different middleware implementations to abstract the user interfaces from the underlying middleware and allow users to execute parallel applications in a uniform way, thus bridging the gap between HPC and HTC. In this work we present the latest developments in MPI-Start and how it can be integrated in the different middleware stacks of EMI, providing a unified user experience for the execution of MPI jobs.
