|Writing Parallel Libraries with MPI - The Good, the Bad, and the Ugly |
(Vol , Nr. , In , presented in Santorini, Greece, pages , , ISSN: , ISBN: , Sep. 2011, Keynote talk at 18th European PVM/MPI User's Group Meeting )
Keynote talk at EuroMPI 2011.
AbstractModular programming is an important software design concept. We discuss principles for programming parallel libraries, show several successful library implementations, and introduce a taxonomy for existing parallel libraries. We derive common requirements that parallel libraries pose on the programming framework. We then show how those requirements are supported in the Message Passing Interface (MPI) standard. We also note several potential pitfalls for library implementers using MPI. Finally, we conclude with a discussion of state-of-the art of parallel library programming and we provide some guidelines for library designers.
