I got to run some work stuff on a big iron itanium 2 machine right around when those came out. it was actually... really good and really fast. but I was not paying for it. can't imagine how much the thing cost.

Beeftweeter posted:was itanium actually any better than x86 (or later x86-64 i guess)? on the particular problem I was working, which was largely numerical and parallelizable but not trivially parallel, yes. it was significantly faster wall-time to solution than competing x86 resources.

in a well actually posted:this was one of the few markets Itanium did well. big fuckin matrices where you could pipeline a shitload of fused multiply-add ops per clock and never, ever needed to branch, and could use the ridiculously huge cache, and you could scale them up as wide as your budget allowed for lots of memory bandwidth (512 sockets per OS image in NASA's SGI super, in ~2004) yup, good old fortran without any conditionals in the speed-sensitive parts of the code

got to run my stuff on a blue gene once, i hated the entire OS setup and arch. it sucked and deserved its death despite whatever marketing hype came out of ibm
