This really isn't an issue so much as it is a general question: Is it possible to determine the currently used CPU scheduler in the kernel?
I've been using -ck after switching from -bfs but still using the BFS scheduler (so I hope). However, recently I noticed my cores aren't all maxed and I'm wondering if that has something to do with it not compiling with the proper scheduler, or if it has something to do with F@H, which has some messages I've never seen before about "Extra SSE boost OK"
I tried googling, and grep'ing through /proc, but I don't know where to look. Found some good articles on the programming behind them, though If it's not possible to find out while it's running, is there some way I could look at the binary or something? Thanks for your help.

[stijn@hermes ~]$ cat /sys/block/sda/queue/scheduler
[noop] anticipatory deadline cfq
If that is the kind of scheduler you're looking for, at least. I always get confused between IO and CPU schedulers...

I think that is the io scheduler since it's listed under sda.

% dmesg | grep BFS BFS CPU scheduler v0.313 by Con Kolivas.
D,oh! Didn't even cross my mind to check dmesg, thank you! It seems it's worknig fine, so it is something different with F@H
@B: Thanks, now I know how to get the io scheduler when I screw with that too
