No, but the standard povray is linked against PVM already. Communication
in povray isn't the rate limiting step, so there isn't much need to use a
variety of parallel libs optimized for performance. PVM provides
heterogenous cluster capabilities, and PVMPOV patches were around years ago,
so I went with PVM. Only one parallel lib can be done (practically anyway)
in one binary.
The povray method of parallelization is pretty gross though. Each slave
parses the .pov file (requiring the .pov file be located at the exact same
location on each node of the cluster), rather than the master parsing it and
multicasting the geometrical data to the slaves.
Does mpi-povray behave the same way? If it's smarter about the parsing,
and still capable of mixed-architecture rendering, that'd be a good
justification to switch over.
