Is Message-Passing Obsolete?

In parallel computing today, an interesting and important debate is taking place. Just as the message-passing paradigm is maturing and becoming standardized through the MPI effort, new shared-memory architectures implemented in both hardware and software are providing a new programming model. Experienced scientists disagree over whether the shared-memory model, advances in compiling techniques, and data-parallel languages like HPF will combine to make the more explicit parallel algorithm approach typified by message-passing obsolete. The speakers in this minisymposium will offer their opinions and experiences. Each speaker has experience with both approaches and can make particularly useful contributions to the debate.
