    sysconf(_SC_NPROCESSORS_ONLN) not working in EM64T RHEL/SuSE

    i am calling sysconf(_SC_NPROCESSORS_ONLN) from my apps code to get number of logical CPUs. this code works with x86, but NOT with EM64T versions. any known issues?

    How do i find number of logical CPUs in EM64T (x64) versions of RHEL & SuSE?

    I think you can just count the number of "processor" lines in /proc/cpuinfo.
