Re: om2.6 What's currently showable ?

Well, I'm working on a round-robin scheduler. But unfortuanately I am
not able to test it really... My latests git-clone/pull-kernel crashes
when booting :( Also only testing on one machine though, without virtual
machines, so far for my cluster...

Please read the README (contained with the src) and provide some input
about what is wished to be written into the wiki.

The source (Python) is available for everyone from the public part of my
private subversion repository. For one/two weeks I made some changes so
that it should round-robin schedule all processes. I would like to share
my effords with the community, if there is any interrest. Therefore I
would like an advice of where to put the code on a public server (like
sourceforge?).

Checkout the code:
 svn co \
 http://nixbox.nixpanic.net/repos/dev/om-userspace/trunk/simplified \
 omus

The README which describes the functions of the daemon should be clear
enough to get it running.

Hopefully it's usefull for someone and looking forward for comments :)

Greetings,
Niels
