Recently saw the forum someone needs to read the system in the Java CPU frequency and usage rate, search the Internet for a while, found some useful things, summed up in this. First, get the CPU frequency 1, read from the registry The key Hklm/hardware/description/system/centralprocessor/0/~mhz in the registry corresponds to the CPU's central frequency. But this method has certain limitations, that is, some

In Linux, view the cpu information-general Linux technology-Linux technology and application information. The following is a detailed description. View cpu information: [Junjie2 @ ljj ~] $ Cat/proc/cpuinfo Processor: 0 Vendor_id: GenuineIntel Cpu family: 6 Model: 13 Model name: Intel (R) Pentium (R) M processor 1.60 GHz Stepping: 8

__cpuidex Read CPU serial number Recent research on the use of __cpuidex, the query to the relevant examples are more complex, so I simplified a part of the content, a simple example, to obtain only the CPU serial number, the final result and through the WMIC command query results consistent.code Example #include Microsoft specificGenerates the CPUID instructi

View CPU 1. AIX and HP:Lsdev-c | grep process | WC-l Lscfg | grep proc lsattr-El proc0 Lscfg | grep mem lsattr-El mem0 2. Solaris:Psrinfo-v | grep "Status of processor" | WC-l Use psrinfo (1 m) to view details. Because of the widespread use of multi-core/multi-thread technology, you can use the-VP parameter to identify the number of physical CPUs, for example: # Psrinfo-VPThe physical processor has 32 virtual processors (0-31)UltraSPARC-T1

During the installation of the virtual machine, the following conditions occur:The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point" Edit the vmx file, that is, the file changed to darwin10 at the beginning, and add the following statement. Cpuid.1.eax = "0000: 0000: 0000: 0001: 0000: 0110: 1010: 0101" The new I3, I5, i7cpu, and vi

1 CPU hotspot Analysis positioning backgroundCPU resources are still very expensive, in order to feel this expensive, the current CPU price of resources:So for the program apes, it is necessary for the program to use CPU resources reasonably and efficiently . using limited CPU resources to solve the actual problems we

CPU clock speed, that is, the clock frequency (cpuClock speed ). In general, the CPU is as high as, And the is the "CPU clock speed ". Many people think that the CPU clock speed is its running speed. The clock speed of the CPU indicates the speed at which the digital pulse s

CPU Cache Most CPUs only have Level 1 cache and level 2 cache, and some have Level 3 cache.The cache memory is the temporary memory between the CPU and memory. It has a smaller capacity than the memory but is faster than the memory. The data in the cache is a small part of the memory, but this small part is about to be accessed by the CPU in a short time. When th
