Two Methods for driving OpenGL Display Walls


Recently the the VMML at the University of Zürich performed a benchmark comparing Chromium and Equalizer on a display wall. The result surprised me, as I would have expected less difference between the two solutions in this setup, since only static display lists are used. Unfortunately neither InfiniBand nor the broadcast SPU were available for this test, which should improve the Chromium performance.

The performance graph is on the left. You can download the White Paper from the Equalizer website.

    Hi there, could you please tell me where to find the two SPUs (InfiniBand and broadcast) for Chromium? I couldn’t find it on the sf.net page. I tried your configuration for running Google Earth with Chromium, but it requires the broadcast SPU.

    Thank you very much.

    InfiniBand is not a SPU, it is a compile-time option/configuration setting for the network layer.

    The broadcast SPU is a proprietary SPU of Tungsten Graphics. You have to contact them to buy a license.
