We are interested in the cost of communicating simple, common, non-contiguous data layouts in various scenarios using the MPI derived datatype mechanism. Our aim is twofold. First, we provide a framework for studying communication performance for non

The Message Passing Interface (MPI) is the prevalent programming model used on today's supercomputers. Therefore, MPI library developers are looking for the best possible performance (shortest run-time) of individual MPI functions across many differe

Autotuning is a well established method to improve software performance for a given system, and it is especially important in High Performance Computing. The goal of autotuning is to find the best possible algorithm and its best parameter settings fo

MPI benchmarks are used for analyzing or tuning the performance of MPI libraries. Generally, every MPI library should be adjusted to the given parallel machine, especially on supercomputers. System operators can define which algorithm should be selec

MPI collective operations provide a standardized interface for performing data movements within a group of processes. The efficiency of collective communication operations depends on the actual algorithm, its implementation, and the specific communic

We examine natural expectations on communication performance using MPI derived datatypes in comparison to the baseline, "raw" performance of communicating simple, noncontiguous data layouts. We show that common MPI libraries sometimes violate these d

The Message Passing Interface MPI is the most commonly used application programming interface for process communication on current large-scale parallel systems. Due to the scale and complexity of modern parallel architectures, it is becoming increasi
