When I render large scene (approx 350MB in memory) with PVMMegaPOV on
one machine with two processors all is OK, but when I try to run it on
second machine through network, pvmd at the second machine takes another
300MB of RAM. After some time it falls down to reasonable size, but it
is strange. It is some bug in PVMegaPOV, or in PVM, or it has some reason?

pvmd itself shouldn't use that much memory. It is just a daemon handling
and buffering messages. It could start increasing its buffers if a huge
number of messages cannot be transmitted to their respective targets.
Could you please give me some more info:
- platform, os, version of pvm (mine is 3.4.2)
- did you use radiosity?
- when does pvmd eat memory (while its clients are
parsing/pre-rendering/rendering)?
- how did the render end (correctly?) and how the loads were balanced
(see the percentages achieved by each client in the stats)
This problem is unknown to me (I mostly run pmp as you usually do), and
was never reported.

i386 (2xPIII800, 1xAMD 850), Linux (RH 6.2), PVM 3.4.3

No. Tried it, but it is slower than at one procesor without PVM :(.

During parsing. When renderings starts, pvmd falls down to reasonable size (under 1MB)

Render ends correctly. Loads are
host name [ done ] [ late ] host name [ done ] [ late ]
Infinity.localdomain [11.69%] [ 0.37%]Infinity.localdomain [ 8.62%] [ 0.00%]
linux [79.69%] [ 0.00%]
(Infinity is 2xPIII800, linux is 1xAMD 850, I think, that AMD is much faster for
render, this has influence of loads)
