atropos

[Ross C Mcilroy]

Hi,

I am working on a project which requires enforced CPU partitioning
between domains, and so was planning to use the atropos scheduler.
However I notice from a previous post that atropos does not seem to be
working.  Has there been any progress in finding the bug?  

I also noticed that Stephan Diestelhorst was working on an alternative
deadline-based scheduler.  Is this ready for use?


Thanks for your help

Ross

AFAIK, no.

I believe it is. I've tried it out and it works pretty well for me. I
believe Stephan has a patch that you can use.

Ross,
  I'm still working at the Atropos replacement, but there a pretty usable 
version (EDF with some fancy addidtions) existing already. If you want to 
have a look at that piece, just tell me and I'll send you a patch!

At the moment I'm trying to implement and test performance enhancing features, 
but I hope to finish a beta soon! So stay tuned :)

Cheers,
  Stephan

Hi Stephan,

Could I have a look at your Atropos replacement?  I don't mind if it is
not finished yet, to be honest I'm getting kind of used to it on this
project :-) (my project, not Xen).  Do you think it would work (with
some minor tweaking by myself) on Xen 2.0.1?  I've patched Xenolinux in
2.0.1 quite considerably to give it MPLS support and "Click modular
router" support, and so I don't really want to move to Xen 2.0.4 (and
thus Linux 2.6.10) unless I really have to.

Thanks

Ross
