I want to render several views of the same scene on a 4-processor Onyx/RE2 (one
RE2 pipeline at this point) in a Performer application.

Is it generally better to configure Performer to use one pfPipe and multiple
pfChannels, using channel groups to share as much state information as
possible; or should I use multiple pfPipes and split the number of channels up
evenly among the pfPipes?

Also, if I get a second RE2 pipeline then obviously I would want multiple
pfPipes, but assuming I still need more pfChannels than I have hardware
pipelines, then I would assume the same partitioning issue applies. (That is,
do I create 2 pfPipes -- one for each RE2 pipeline -- and split up the
pfChannels among them or do I create multiple pfPipes per hardware pipeline and
reduce the number of pfChannels per software pipe (i.e. pfPipes)?)

Thanks
