HI
I installed Three Pentium 133/32Mb/1.7Go computers in a beowulf cluster
with PVM 3.4.1. I compiled POV 3.1e.1 with the pvmpov patch. Until
there, everything ran quite well.
BUT ....
Rendering SHAPES.POV without PVM (-N) : rendering time is 4 mn 29 s.
Rendering the same with the three computers : rendering time is 5 mn 47
s.
PVM seems to work correctly, I can add all the computers wiithout any
problem.RSH functions correctly too.
I use NE2000 10Bt compatibles NICs. No DNS, no gateway.
In fact, I just followed the Pondermatic howto found at
www.cris.com/~rjbono/html/pondermatic.html
If someone can help, I'd like to understand.
Thanks.

PS : sorry, my english is maybe not as good as I would like it to be.
