Abstract

This article describes two software tools, AutoMap and AutoLink, that facilitate the use of data structures in MPI. AutoMap is a program that parses a file of user-defined data structures and generates new MPI types out of basic and previously defined MPI data types. It also localizes error checking of actual and MPI assumed default layout of data structures in the software tool, instead of with the user. AutoLink is an MPI library that allows the transfer of complex, dynamically linked, and possibly heterogeneous structures through MPI. AutoLink uses files generated by AutoMap to automatically define the needed MPI data types. We describe each of these tools, and give an example of their use. Finally we discuss the internals of AutoLink design, and focus on the performance rationale behind them.
