IMPI: Making MPI Interoperable
The Message Passing Interface (MPI) is the de facto standard for writing parallel scientific applications in the message passing programming paradigm. Implementations of MPI were not designed to interoperate, thereby limiting the environments in which parallel jobs could be run. We briefly describe a set of protocols, designed by a steering committee of current implementors of MPI, that enable ...
متن کاملThe Interoperable Message Passing Interface (IMPI) Extensions to LAM/MPI
Interoperable MPI (IMPI) is a protocol specification to allow multiple MPI implementations to cooperate on a single MPI job. Unlike portable MPI implementations, an IMPI-connected parallel job allows the use of vendor-tuned message passing libraries on given target architectures, thus potentially allowing higher levels of performance than previously possible. Additionally, the IMPI protocol use...
متن کاملTowards Asynchronous and MPI-Interoperable Active Messages
Many new large-scale applications have emerged recently and become important in areas such as bioinformatics and social networks. These applications are often data-intensive and involve irregular communication patterns and complex operations on remote processes. Active messages have proven effective for parallelizing such nontraditional applications. However, most current active messages framew...
متن کاملMaking MPI Intelligent
Mapping parallel applications to multi-processor architectures requires information about the execution times of the concurrent processes to find an optimal allocation and must take into account the interprocessor communication at runtime, whose overheads have emerged as the major performance limitation. However, both information cannot be statically known in advance. In this paper we present a...
متن کاملStatus Report on the Development of the Interoperable Mpi Protocol
| An industry lead eeort to create a protocol for the interoperation of implementations of the Message Passing Interface (MPI) has been ongoing since March of 1997. Meetings have been held several times per year with many implementors of MPI participating to help deene the Inter-operable MPI protocol (IMPI). This process has resulted in a simple protocol that can be incorporated into existing i...
