Re: dual core processor

Maybe this explains it???? I turned on HT and now can see 2
processors both in Device Manager & Task Manager. So dual core at this time
is a myth???





Intel® Processor Family
Projected Platform Release Date

Intel® Itanium® 2 Dual-Core Processor
4QTR, 2005

Intel® XeonT Dual-Core Processor MP
4QTR, 2005

Intel® XeonT Dual-Core Processor

None of the Intel links list dual core - bah humbug! What a misuse of time
& expectation. I am still investigating the effect of turning HT on/off and
setting the affinity. I'm tired - time to go home to
sleeeeeeeeeeppppppzzzzzzzz..........................
