Re: Dual-Core CPU's
Do the foll:
cat /proc/cpuinfo
It will list the no. of cpu's, speed etc.
Cheers

Re: Dual-Core CPU's
But I cannot see any "siblings 2", as described by Bill.
Is this a single dual-core CPU system with Hyper-threading? Or a single 4-core CPU with no Hyper-threading? How can we differentiate them?
Thanks.

'siblings' is set to 2 here, whilst 'physical id' is set to 0 for both. I've not seen a 'cpuinfo' output for one of the new dual-core intel x86-based CPU's, and I'm pretty sure Itanium's don't use 'Hyper threading', so..
In any case, as can be seen from Ivan's output, there are no 'physical id's involved with Itanium systems.
(aside: HP have a 16-way Itanium-2 system running RHAS4 up on testdrive! Woo!)
