Désolé de doucher votre (et mon) enthousiasme...
Voici le mail que j'ai reçu ce matin (issu de la Mail-Liste Fortran).
Ca fait un moment qu'on attend les 64 bits pour les calculs intensifs, mais il semble (selon ce mail) que ça serait pas Power4...
J'aimerais qu'il se trompe !!!
Voila le texte:

Folks,
I attended a briefing today on IBM's high performance computing technology,
which is hinged on their Power4 CPU (this CPU has awesome performance in the
various real-world benchmarks I have seen). After the briefing, I asked the
presenter (a chief engineering manager from IBM) about the Power4 derivative
for desktops and low end servers to be announced in October. You may recall
that there has been speculation that this CPU would find its way into
PowerMacs in the future. Well, it sounds like this CPU is not in Apple's
future -- the "over 160" vector instructions are not AltiVec (even though
AltiVec has 162 instructions), and there are technical issues that would
prevent AltiVec from ever marrying with Power4 or its successors.
Furthermore, the guy came right out and said that they have pitched the
desktop Power4 to Apple, but Apple was not interested.
So, although Power4-based PowerMacs seemed like a promising (and likely)
possibility, it looks like it won't happen. I guess we will have to wait
and see what Apple has in store for the future . . . .
