Are you using Linux? Don't know why it doesn't work for my Pentium D. Actually my Windows seems not show two processors at first, while the API may depend on OS. My Linux has no problem with this. On the other hand, even your case is undesirable for Hyperthreading since we probably want more detailed info about processor(s) since hyperthreading sometimes wants to be treated differently than real SMP (or dual-core). I believe there is such kind of API available somewhere, at least NUMA support of Linux from SGI has it.
I use WindowsXP and here is more detailed info about CPU: Number of processors 1 Number of cores 1 per processor Number of threads 2 (max 2) per processor Name Intel Pentium 4 660 Code Name Prescott Specification Intel(R) Pentium(R) 4 CPU 3.60GHz Package Socket 775 LGA And I see 2 CPUs in Windows Task Manager. Did you tried Runtime.getRuntime().availableProcessors() ? -- Mikhail Fursov
