hi
1. Do I need the O(1) scheduler to run a heavily I/O bound server application
with some 200-500 concurrent threads?
2. If so - can I find the O(1) scheduler somewhere for 2.4?

2.4.19-ac/2.4.20-ac, Red Hat 7.3, Red Hat 8.0, and probably quite a few
other places. I think Robert had a set of patches versus plain 2.4.19
too

Unfortunately some of the scheduler bits that have been merged into
2.4.20-pre have broken the nice patch that robert has, I'm hoping he can
re-diff it for us (me) because I like to have the option of getting O(1)
without using Alan's tree.
Good luck.

Yep, see:
http://www.kernel.org/pub/linux/kernel/people/rml/sched/ingo-O1/
I would recommend using 2.4-ac over mainline with my patches, however.
Alan's tree is well-tested and I send him scheduler fixes quicker than I
update my own patches :)
It has lots of other nice bits, too.

I just put a 2.4.19 final patch up. I will do a 2.4.20-pre/2.4.20 patch
eventually but it is not at the top of my list. I would not think
managing the rejects is too difficult.
It is a much higher priority keeping the 2.4-ac and 2.5 scheduler sane.
