AutoMap and Autolink Tools for Communicating Complex and Dynamic Data-Structures Using MPI

摘要

This article describes two software tools, AutoMap and AutoLink, that facilitate the use of data-structurs in MPI. AutoMAp is a program tat pases a file of user-defined data-structures and genrates new MPI types out of basic and previously defined MPI data-types. OUr software tool automatically handles specialized error checking related to memory mapping. Autolink is an MPI library that allows the transfer of complex, dynamically linked, and possibly heterogeneous structurees through MPI. AutoLink uses files generated by AutoMap to automatically define the needed MPI data-types. We describe each ofthese tools, and give an example of their use. Finally we discuss the internals of Autolink Design, and focus on the performance rationale behind them.
