Here we will show you today How can you Download and Install Tools App CPU-Z on PC running any OS including Windows and MAC variants, however, if you are interested in other apps, visit our site about Android Apps on PC and locate your favorite ones, without further ado, let us continue. More from Us: Snaky Snake For PC (Windows & MAC). Despite being in beta, the speed and accuracy with which it offers all the information make it an excellent application. (The old version still worked perfectly well if you just ignore STDERR, which is all the modification does for you.CPU-Z is an excellent hardware information tool in Windows and also it is in Android. When this question was asked the OP did not say that he wanted the number of LOGICAL cores rather than the actual number of cores, so this answer logically (no pun intended) answers with a way to get the actual number of real physical cores, not the number that the OS tries to virtualize through hyperthreading voodoo.ĭue to a weird bug in OS X Yosemite (and possibly newer versions, such as the upcoming El Capitan), I've made a small modification. Hw.logicalcpu_max: The maximum number of logical processors that could be available this boot. Hw.logicalcpu: The number of logical processors available in the current power management mode. Hw.physicalcpu_max: The maximum number of physical processors that could be available this boot. Hw.physicalcpu: The number of physical processors available in the current power management mode. This number can change when power management modes are changed. Use this number to determine the number threads to create in SMP aware applications. Hw.activecpu: The number of processors currently available for executing threads. Use this value for sizing of static per processor arrays i.e. Hw.ncpu: The maximum number of processors that could be available this boot. Interesting values to use in place of 'hw.logicalcpu', which counts cores, are (from this comment in the kernel source): Sysctlbyname('hw.logicalcpu', &count, &count_len, NULL, 0) įprintf(stderr,'you have %i cpu cores', count) To do this in C you can use the sysctl(3) family of functions: int count
