Dennis, All the machines I've seen start with 0 for the first CPU, and count up from there. A dual Xeon with hyperthreading reports: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.66GHz stepping : 7 cpu MHz : 2666.613 cache size : 512 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pa se36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 5259.26 processor : 1 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.66GHz stepping : 7 cpu MHz : 2666.613 cache size : 512 KB physical id : 0 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pa se36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 5324.80 processor : 2 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.66GHz stepping : 7 cpu MHz : 2666.613 cache size : 512 KB physical id : 3 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pa se36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe cid bogomips : 5324.80 processor : 3 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Xeon(TM) CPU 2.66GHz stepping : 7 cpu MHz : 2666.613 cache size : 512 KB physical id : 3 siblings : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no
