Tips for running MPI versions

Tachyon support the use of MPI for distributed memory rendering of complex scenes. Most commercial supercomputers and cluster vendors provide their own custom-tuned implementations of MPI which perform optimally on their hardware. Homegrown clusters typically use either the LAM or MPICH implementation of MPI. While Tachyon will work with any comformant implementation of MPI, some implementations perform much better than others. In the author's experience, the LAM implementation of MPI gives the best performance when used with Tachyon.
