Hi Ingo,
I just thought I would mention this, because it is certainly on my
mind. I can't help wondering if other folks are also concerned about
this. The thing is, why don't you just send your patches to Con who
got this whole ball rolling and did a bunch of great work, proving
beyond any reasonable doubt that he is capable of maintaining this
subsystem, whatever algorithm is finally adopted? Are you worried
that Con might steal your thunder? That somehow the scheduler is
yours alone? That you might be perceived as less of a genius if
somebody else gets credit for their good work? NIH?
My perception is that you barged in to take over just when Con got
things moving after the scheduler sat and rotted for several years.
If that is in any way accurate, then shame on you.
Clearly you have no idea what's going on, or how development is done.
These are mutually exclusive different ideas on what constitutes an
optimal scheduler, and not in any way improvements on the same thing,
but total replacements for the algorithm of the scheduler.
And Ingo has been doing scheduler work for a very long time, while until
recently Con was working on the staircase scheduler as a solution for
desktop use, and it was not (to my taste) a candidate for a general
scheduler until the deadline discussion and some ideas from wli resulted
in improvements resulting in more robust performance under typical
server loads.
You also seem to be unaware of the work done by Nick Piggin in
nicksched. There are a lot of mutually incompatible approaches being
evaluated, and that's good for the future.
