>>> Le quad-core de base est, pour un développement actuel, la machine bureautique "type" si on ne veut pas s'enfermer dans des optimisation pour 1% de la planète d'ici deux ans.
Ingo Molnar est de ton avis :
"But when it comes to scheduler design and merge decisions that will trickle down and affect users 1-2 years down the line (once it gets upstream, once distros use the new kernels, once users install the new distros, etc.), i have to "look ahead" quite a bit (1-2 years) in terms of the hardware spectrum.
Btw., that's why the Linux scheduler performs so well on quad core systems today - the groundwork for that was laid two years ago when scheduler developers were testing on a quads. If we discovered fundamental problems on quads _today_ it would be way too late to help Linux users.
Hope this explains why kernel devs are sometimes seen to be ahead of the hardware curve. It's really essential, and it does not mean we are detached from reality. ".
