How to determine the hardware (CPU and RAM) on a machine?

Question

I\'m working on a cross platform profiling suite, and would like to add information about the machine\'s CPU (architecture/clock speed/cores) and RAM(total) to the report of

Answer 1

On Solaris:

-For memory

 prtconf | grep Memory

-For CPU

 psrinfo -v | grep MHz

Answer 2

On Windows you can use GlobalMemoryStatusEx to get the amount of actual RAM.

Processor information can be obtained via GetSystemInfo.

Answer 3

Here is one method for getting the information you want on a Windows machine. I copied and pasted it from an actual project with some minor modifications, so feel free to clean it up to make more sense.

        int CPUInfo[4] = {-1};
        unsigned   nExIds, i =  0;
        char CPUBrandString[0x40];
        // Get the information associated with each extended ID.
        __cpuid(CPUInfo, 0x80000000);
        nExIds = CPUInfo[0];
        for (i=0x80000000; i<=nExIds; ++i)
        {
            __cpuid(CPUInfo, i);
            // Interpret CPU brand string
            if  (i == 0x80000002)
                memcpy(CPUBrandString, CPUInfo, sizeof(CPUInfo));
            else if  (i == 0x80000003)
                memcpy(CPUBrandString + 16, CPUInfo, sizeof(CPUInfo));
            else if  (i == 0x80000004)
                memcpy(CPUBrandString + 32, CPUInfo, sizeof(CPUInfo));
        }
        //string includes manufacturer, model and clockspeed
        cout << "CPU Type: " << CPUBrandString << endl;


        SYSTEM_INFO sysInfo;
        GetSystemInfo(&sysInfo);
        cout << "Number of Cores: " << sysInfo.dwNumberOfProcessors << endl;

        MEMORYSTATUSEX statex;
        statex.dwLength = sizeof (statex);
        GlobalMemoryStatusEx(&statex);
        cout << "Total System Memory: " << (statex.ullTotalPhys/1024)/1024 << "MB" << endl;

For more information, see GetSystemInfo, GlobalMemoryStatusEx and __cpuid. Although I didn't include it, you can also determine if the OS is 32 or 64 bit via the GetSystemInfo function.

Answer 4

I've written some code which uses the WMI service to get the Max Clock Speed, I know it's VB.net but it shows the idea:

''' <summary>
''' Use WMI to get the Clock Speed in Hz
''' </summary>
Public Function GetMaxClockSpeedInHz() As Double
    Dim manObj = New ManagementObject("Win32_Processor.DeviceID='CPU0'")
    manObj.Get()
    GetMaxClockSpeedInHz = Convert.ToInt32(manObj.Properties("MaxClockSpeed").Value)
End Function

Answer 5

On Linux you can parse /proc/cpuinfo (contains a block of info on each processor) and /proc/meminfo (contains a variety of general memory statistics, including MemTotal).
