[SSI-users] OpenSSI versions

[Scott W. <sc...@sl...>]

Hi all,

(Trying again with a subject line... third time's the charm they say...)

>From http://openssi.org/cgi-bin/view?page=openssi.html :

#  OpenSSI 1.9.6 Preview Updated
    * version for Debian Lenny i386 updated 2010/02/18
    * version for Debian Lenny updated 2010/01/07
    * version for Debian Etch updated 2010/01/07

...

#  OpenSSI 2.0.0pre2 Now Available
    * version for Fedora Core 3 released 2008/01/03

Roughly, what are the differences between 1.9.6 and 2.0.0pre2?

Was there a fork at some point with development happening
concurrently on the 1.9.x branch and the 2.0.x branch?  Or is
the Debian work just lagging in cluster software version?

http://wiki.openssi.org/go/Roadmap partially answers that question
(2.0.0preX reserved for kernel 2.6.18 or higher).

I'm pretty sure I installed 1.9.6 for Debian Lenny (x86), but
`cluster -r` reports:  "This is cluster software release 1.9.3".
That's kind of tangential, but I can't help wondering if that can
easily be accounted for.

`cluster -m` reports 15, and I'm approaching that number of machines
here.  Also, one of the photos at http://wiki.openssi.org/go/Showcase
kind of suggests that clusters with more nodes exist.  Can this limit
be easily increased in config?  I thought I read somewhere that
the 1.2 stable branch had a similarly low limit but newer 1.9 versions
allowed for hundreds of machines in the cluster.

Do I (currently) need to run the Fedora Core version to throw nodes at this?

I'm continuously in awe of OpenSSI.  Thank you for your work and
for your attention.
