Hi, i've been doing some tests to the the opensg 1.6, in a display wall
(4x3 configuration). I've found a couple of things:
-The tutorial for the clusterServer doesn't free memory after the client
is finished. Because we're benchmarking the wall we run several tests
from a script and after a few run's the server's started to crash. We
suspected some sort of memory leak, and after some manual checking with
ps, i found that the server's process eats up about 2gb of memory after a
few run's displaying some hi-res models. We're a bit new to this (opensg)
but we tried to see if there was a way to plug the leak... we didn't find
many references, so we tried to destroy the glut window, and the
ClusterServer and create new ones when the cliente finishes. This almost
worked, but the memory alocated for the model still remained. Does anyone
know a good way to fix this memory leak? For now, we just finish the
server process when it detects that the client finishes and with a bash
script lauch it again in a endless loop.
-When running on the wall, we made a test where the model started centered
inside a tile, and moved in a straight line threw all the other tiles. On
high resolution models, there is a small delay when the model hit's the
tile's boundry. This delay is considerable, specialy on models with
textures. We have a small model, about 3000 triangules, with textures that
hits the boundry, stop's for about 1 second and then moves on. Is this a
bug? feature? problem? Any known way to solve this?
-We noticed that 1.6 also brought BalancedMultiWindow Class. Correct me if
i'm wrong, but this is supost to work like the MultiWindow class, except
that less loaded server's get the load of more loaded server's, maximazing
the speedup. Is this correct? If so, could some one give me an example of
how it work's, because we used it, but the model isn't displayed properly
like in the MultiWindow Class. We just replaced the declaration of the
type of window. Do we have to do something else? We would like to try this
new class and see the results.
Thank you for your time, and i apologise for my rusty english,
