Unusual question designed to shortcut doing some actual research: What scheduling algorithms are actually used in the wild?
19:30
<@sshine>
has anyone here made GitHub pages work? http://standardml.dk/ is supposed to point to my repo at https://github.com/sshine/standardml.dk -- but I can't see what I'm missing. maybe the DNS hasn't propagated fully yet. the ten minutes that GitHub mention should have passed by now.
19:30
<@sshine>
Tarinaky, OS process scheduling?
19:33
<@Tarinaky>
sshine: Right.
19:33
<@sshine>
Tarinaky, Linux uses http://en.wikipedia.org/wiki/Completely_Fair_Scheduler
19:34 * sshine shudders at Google for injecting stuff into URLs. I found this comparison powerpoint between different OSes: http://www.google.dk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0CDYQFjAB&url= http%3A%2F%2Fwww.wpi.edu%2Facademics%2Fcs%2F~cs535%2Fs03%2Frajaram.ppt&ei=1nVcUf TwFM3KtAai74D4Bg&usg=AFQjCNEKSN-n9pgQF0kdXvJ2e26ANRDazg&sig2=39SW3ciX1N2OF0PWRH_ V3A&bvm=bv.44697112,d.Yms&cad=rja
19:34
<@Tarinaky>
Context for question: Datastructures and Algorithms assignment where the lecturer has given us a java program that simulates a job list and we have to implement Scheduling algorithms that plug into the simulator.
19:35
<@sshine>
ok. the CFS, as I've just read, doesn't even use a queue, but an RB-tree... so that's pretty cool.
19:36
<@Tarinaky>
brb
19:40
<@sshine>
Tarinaky, the CFS scheduler replaced the O(1) scheduler. I don't think its name really says anything more than the scheduling time, and not how it actually prioritizes jobs.
19:41
<@Tarinaky>
Yeah. Oh well.

20:20 * Tarinaky glares at his code for not working.
20:23
<@Tarinaky>
Okay. Am I being thick.
20:24
<@Tarinaky>
Because it appears to work as I expect if I swap the definition for the comparator.
20:25
<@Tarinaky>
The documentation for java.util.Comparator explicitly says: "negative integer... as the first argument is less than the second"
20:25
<@Tarinaky>
So why does if ( arg0.getPriority() < arg1.getPriority() ) return -1; result in the job with the smallest integer for priority being at the top of the heap.

Yeah, it's pretty common to sort lists in ascending order by default, and by analogy, default to smallest-first for other sorted data structures.

Well now I know /why/ my assumptions were violated I feel better about the fix.
