The multicore “crisis”
2007/06/12
“Why upgrade if it will not feel faster? That’s why the industry is in a panic. That’s what the multi-core “crisis” is about.” (ref)
“Most of this is already solved, just forgotten. Ask Dave, or read the papers from that era, that’s what I do. (Now I fear I’m giving away my secret of avoiding hard problems by just looking up the answer.) Computer Science has a collective 20-year amnesia cycle going I cannot explain, sadly this is getting even shorter. A recent conference I was at was just depressing. That’s probably the real crisis in CS.” (ref)

Νομίζω ότι το γενικό it doesn’t feel faster έχει να κάνει με το software και μόνο.

Ιδίως το quote με το 20-year amnesia μου θυμίζει αυτό λέω συχνά :
computer science …. my arse
:p
Αλλά δεν έχουνε και πολύ άδικο, ιδίως στο cs κάνουνε πολλούς κύκλους σε τεχνολογίες (απο distributed, σε συγκεντρωμένα, τώρα πάλι σε distributed).

To γενικό “it doesn’t feel faster”, αποτελεί το θεμέλιο λίθο της εμπορικής πλευράς της IT. Όταν ένα οικοσύστημα πάρει μπρος, δύσκολα σταματά ή κάνει πίσω.

[...] Here is my problem with all this back and forth: we’ve already hit the Multicore Brick Wall without leaving skid marks and most people just don’t realize it! I hear the crowd out there now, beyond the klieg lights, grumbling in the dark, ”What’s he on about now?” Patience please. The problem with multicore is it teaches us that someday we will expect software to scale linearly. That Alpha Geek Speak means if I double the number of available cores, I want my software to run twice as fast. Hallelujah! I’m back to getting twice the speed every 18-24 months just like in the heyday of Moore’s Law. In the post-clockspeed-doubling world that’s coming, this will be a requirement or all computing progress grinds to a halt (that means the money stops: true crisis), or so say the Multicored Chicken Littles.
