[vizstack-users] [Announcement] VizStack 1.1-2 is out !

[Kumar, S. <shr...@hp...>]

VizStack 1.1-2 is out ! Please download and try it out from the usual place http://sourceforge.net/projects/vizstack/files/.

This supports multiple remote desktop sessions per GPU and many more enhancements and bug fixes. 

I'm pasting some text from the announcement at http://vizstack.sourceforge.net/?p=88 below

----

Support for multiple remote desktop sessions per GPU is surely the most awaited feature of this 
release. It is possible to control the number of users that share a GPU on a per-GPU basis.

You will also find several enhancements and fixes that make like better (I'll mention only the 
most important ones here)

    * Binary packages for RHEL5, SLES11, Ubuntu 9.10 and SLES10.
    * VizStack now uses libxml2 for parsing - so just download and install on any Linux distro!
    * VizStack can compensate for bezels in Tiled Displays using "invisible pixels". Note that current 
       nvidia drivers have issues w.r.t handling these, so this may or may not work for you.
    * The Remote Access Tools can allocate whole nodes for users. Since GPUs can now be shared, you can 
      allocate a complete GPU all for yourself too.
    * Support for a "fast" network; this can be used by parallel applications.
    * The configure script can now generate templates for GPUs and display devices not known to it. This 
      should make it easy to get those first things up and running. This also means that GPUs meant for 
      compute purposes, e.g. Tesla series cards, should work with VizStack (hasn't been tested, though). 
      GeForce cards should work too.
    * Templates for Displays(including EDID files), GPUs, Keyboards and Mice are loaded from the master 
      node. There is no need to propagate these files to the slave nodes in a cluster. Also, the node 
      configuration file is picked up only from the master node.  These minimizes impacts of cluster 
      management techniques like Golden Imaging.
    * The documentation just got better, and is now split into a User Guide, and an Admin Guide; a developer 
      guide also makes an appearance, though admittedly it is still basic !
    * Small fixes and face-lifts have been given to most user scripts (viz-*)
    * Some more samples scripts show usage of VizStack's Python API
          o Script that can run applications written using the Equalizer framework
          o Script that shows how to run benchmarks in parallel. Run SPECViewPerf 9 in parallel on all 
            GPUs of a cluster. Benchmark a whole cluster in 30 mins - sweet ! Another example shows how 
            to run the CUDA bandwidth test on all GPUs.

If you are upgrading from an earlier release (e.g., 1.0-2), note that any XML template files you may have 
created are now invalid. Please keep backups of this. Sorry for this break from backward compatibility, but 
it was necessary !

I need to thank the following individuals for their contributions

    * Simon Fowler : found a few issues in VizStack on Ubuntu, requested support for Bezels, and generally 
      for being the first (and very active) subscriber on the mailing list :-) Simon also contributed templates 
      for the Dell 3008WFP monitor, and the Quadro NVS 420 card.

    * Paul Melis : suggested source documentation changes.
