• Status: RESOLVED WONTFIX
• Product: Gentoo Linux

It'll be nice to add the batch scheduling patch from Con Kolivas, I run setiathome and is very useful for running it.

What kind of architecture are you on? Is it a Pentium4 with Hyperthreading? 

[Comment 2 Pablo 2004-03-26 00:35:04 UTC]

Nop, I'm on Athlon Tbird.

Are you referring to the scheduling patches in the current mm tree or the ck tree? The patches in the mm-tree are already included in g-d-s. Con's patches in the ck-tree are very cheap hacks that (should) degrade performance on non SMT machines.

I'm referring to Batch scheduling "which allows tasks to only use cpu time if the cpu is idle, rather than a proportion of cpu usage that "nice" does. This is useful for distributed computing clients like setiathome. To set a task as SCHED_BATCH you need to use the schedtools utility."

I don't know if it is a cheap hack but it is the only thing I miss on g-d-s :)

Sorry, but if you want Con's patches, please use the ck-sources package, I will
not apply them to the main gentoo-dev-sources package.
