Subject: [ANNOUNCE] Staircase Deadline cpu scheduler version 0.46
Date: Sunday, April 22, 2007 - 11:03 am

Yet another significant bugfix for SMP balancing was just posted for the 
staircase deadline cpu scheduler which improves behaviour dramatically on any 
SMP machine.

Thanks to Willy Tarreau for noticing more bugs.

As requested was a version in the Makefile so this version of the patch 
adds -sd046 to the kernel version.

http://ck.kolivas.org/patches/staircase-deadline/2.6.21-rc7-sd-0.46.patch
http://ck.kolivas.org/patches/staircase-deadline/2.6.20.7-sd-0.46.patch

Renicing X to -10, while not essential, may be desirable on the desktop. 
Unlike the CFS scheduler which renices X without your intervention to 
nice -19, the SD patches do not alter nice level on their own.

See the patch just posted called 'sched: implement staircase deadline 
scheduler load  weight fix' for details of the fixes.

Thanks to all testing and giving feedback.

Well I'm exhausted...
