VMPI

A presently unreleased tool which is used for distributed compiles, reducing the compile time by distributing the work among multiple networked machines. The Source Engine features page, under the tools header, implies that Vmpi is included to licensees as part of the Source Engine package.

Options

Vmpi seems to be called by applications such as Vvis and Vrad through two commandline switches:

-mpi : Use VMPI to distribute computations.

-mpi_pw <pw> : Use a password to choose a specific set of VMPI workers.
