I read the article Detecting Multi-Core Processor Topology in an IA-32 Platform. I found valuable info on detecting physical and logical processors inIA-32. Can you tell where to find similar info for 64-bit machines?

There is a corresponding CPUID call for x64 architectures: cpuid64. Check out CPUID for x64 Platforms and Microsoft Visual Studio* .NET 2005 for details on how to use this. If that's not enough, you could try contacting the authors of the IA-32 paper to see if they have any additional info.
