Hi Leaps! .. Nahhh .. It's 2xXeon Quads on a Skultrail Mobo :) [Heinz, Please check cache size with CPU-Z]

[Hmmm, so parallel composer doesn't actually have TBB in it then .... ??? that seems a bit odd, maybe they expect you'll use pure openmp.. what about IPP, I suppose that's not there either which would make this ICC 11 ?]
32 & 64 bit fibonacci sample built & ran. Will consider fully migrating to 64 bit platform for holidays in a few weeks. It'll be painful, but about time probably.

I did upload the fibonacci project to our testproject
it is in /users/heinz/heinz_projects/fibonacci/vc8
As far as I have seen IPP will be used if it is installed...but must read doku to manifest it..
Looked up now: --->
Vectorization and Loop Optimization
Vectorization detects patterns of sequential data accesses by the same instruction and transforms the code for SIMD execution, including use of the SSE, SSE2, SSE3, SSSE3, and SSE4 instruction sets.

did you see the speedup between the easy TBB and the composer with TBB. my testresultfiles are up. ;D

Jason G:
@heinz: I didn't check yet ... wait up.. this is fun... will compare 32 bit Fibonacci here.
@Leaps: Will PM shortly about something

there you can see CPUID
and here you can see CPUZ
Jason G:
Ahhh, 6 meg per package ( 1.5 meg per core )... Okay, yep it is 12 meg total for the 8 cores.
Compared 32 bit ICC 10.1 / TBB 2.0 build of fibonacci, and it IS slower than Parallel composer 32 bit build under XP64 ... Will have to try that build under XP32 to confiirm though. I will probably update all my ICC/IPP base packages as soon as I get time, in a few week.
