: Towards an MPI Benchmark Tool for Performance Guideline Verificationar of the standard MPI 2.2 collective operations. The benchmark is intended to facilitate comparisons between different ways of expressing the same functionality towards performing automatic detection of violations of self-consistent MPI performance guidelines. The benchmark can be used by MPI libra

Micro-applications for Communication Data Access Patterns and MPI Datatypes MPI datatypes are a way to avoid such intermediate copies and optimize communications, however, it is often unclear which implementation and optimization choices are most useful in practice. We extracted the send/recv-buffer access pattern of a representative set of scientific applications into mic

Leveraging MPI’s One-Sided Communication Interface for Shared-Memory Programming has become a dominant approach to scalable parallel programming. While this model provides a great deal of flexibility and performance potential, it saddles programmers with the complexity of utilizing two parallel programming systems in the same application. We introduce an MPI-integrated shared-m

MPI Functions and Their Impact on Interconnect Hardware be implemented in a very efficient way. The specification of various MPI functions is analyzed and the impact to interconnect hardware is presented. A careful analysis of latency components and pipeline structure must be done in order to map the MPI functions to hardware in an efficient way.
