nVidia actually sent me a K5000 for testing, and I determined that the IFR stuff is not any faster than using PBOs, as VirtualGL currently does. Thus, I don't currently see any advantage to IFR, although I have it on my things-to-do list to look at the NvENC API (which allows for onboard compression of H.264 video.) How to take advantage of that in the near term is an open question, since it doesn't fit well with the X proxy paradigm. It would more be something that a custom solution built around VirtualGL might take advantage of-- perhaps a solution dedicated to games or other immersive full-screen apps (flight simulators, CAVEs, etc.), for which H.264 makes the most sense. Anyhow, I mainly want to benchmark it and see if it falls within the zone of usefulness. ------------------------------------------------------------------------------ Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft _______________________________________________ VirtualGL-Users mailing list VirtualGL-Users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/virtualgl-users
