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) If you see x86_64 in the output, it is x86 and 64-bit.To do this in C you can use the sysctl(3) family of functions: int count
The command above displays an output similar to the example output below. Using the uname command, you can determine if your Linux kernel is 32-bit or 64-bit by running the command below. flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni monitor ds_cpl est tm2 ssse3 cx16 xtpr sse4_1 lahf_lm Determine if the Linux kernel is 32-bit or 64-bit Below is an example output of the command above with lm in the information. If you don't see lm or see i386, i486, i586, or i686 in the output, then the CPU is 32-bit. If lm is found in the output, then the CPU is 64-bit. (Intel has an amazing proliferation of part numbers.) sysctl -n. LinuxĪccess the command line interface on the Linux operating system, and enter the following command. To see it, there’s a nifty UNIX shell command that provides just a little more detail on this particular CPU.

The table above shows that all the most recent Mac computers are 64-bit processors. Once listed, perform an Internet search, using the CPU's processor name as a keyword, to determine if it's a 32-bit or 64-bit CPU. Open the Hardware section and find the Processor Name attribute.On the About This Mac window, click the More Info option.Select the About This Mac option in the Apple menu.Click the Apple icon in the menu bar at the upper-left corner.On a macOS computer, follow these steps to determine if the processor is 32-bit or 64-bit. There are no 64-bit versions of these operating systems.
MAC CPU INFO COMMAND WINDOWS
Windows operating systems, from Windows 95 to Windows 2000, are all 32-bit. Typically a command assumes default values for some of the optional. Some commands have required arguments, and most have some set of optional arguments. Each specific command contains its own set of arguments that are of the form argumentvalue.
