Detecting number of Physical CPUs in Intel Hyperthreaded CPU systems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Does anyone know how I can determine the number of physical processors
on a machine with Intel Hyperthreaded CPUs? I have code from Intel which
will report the number of physical CPUs on a windows system. It uses the
Win32 process affinity stuff to issue commands on specific CPUs so it
isn't portable to Linux. I was hoping I could simply read /proc/cpuinfo.
The /proc/cpuinfo I looked at on a 2.4.? machine didn't appear to have
enough information.

Thanks,

Ken
