hi,
We just got an SGI graphics cluster (very cool machine)
but cannot get cfly to run unless it is set to -m 0
(PFMP_APPCULLDRAW), so no multiprocessing. This may be
the source of the frame glitches we're getting as well.
can some one give me insight into this? is multi
processing in linux not yet ready for prime time? is
there something I can tweak or tune to either split
the procs, or get rid of the frame glitches? If I
free run, the frame rate for performer town is about
60 hz, with frame miss counts running between zero
and 25-30. app time is typically 7-9 msec, draw is
typically 9-12 msec. cpu loads are about 50% of one
cpu (each node has two of course). If I run in frame
lock mode, the frame rate is typically slower, and
we still get a lot of frame misses.
It seems like this machine could run much faster and
smoother than I am seeing it do.
And, for those of you who don't need IRIX, I highly
recommend the cluster. so far.
thanks
ken
