Hi all,
We are using Equalizer on two different setups:
1. 1 Node with 4 graphics cards (nvidia quadro with 2 outputs each)
2. 6 nodes with 1 graphics card each.
We use Ubuntu on all machines. The setup is meant to run a 3 sided cave. We
have 1 window per pipe and 1 channel per window. Each channel is assigned to
one wall.
We implemented a stress test application to test the two different setups.
The application contains 3 stanford dragons.
If we start the second configuration with multiple nodes, we get a result of
about 65 fps.
If we start the first configuration, the framerate is about 17 fps only. The
strange thing is, that the framerate increases if we remove pipe(s) from the
configuration. It seems as if the whole scenegraph is rendered on each pipe,
which is not really the purpose of Equalizer I think.
Did anyone experience similar problems?
The configuration file for setup 1 is posted below.
Cheers,
Brigitte
