The number of available hardware counters in a processor is limited while each CPU model might have a lot of different events that a developer might like to measure. Each counter can be programmed with the index of an event type to be monitored, like a L1 cache miss or a branch misprediction.
A system monitor displaying system resources usage. A system monitor is a hardware or software component used to monitor system resources and performance in a computer system. [1] Among the management issues regarding use of system monitoring tools are resource usage and privacy. Monitoring can track both input and output values and events of ...
In robots and other automated machines, a fault in the control computer could cause equipment damage or injuries before a human could react, even if the computer is easily accessed. A watchdog timer is usually employed in cases like these. Watchdog timers are also used to monitor and limit software execution time on a normally functioning computer.
On the Windows platform, many programs designed to monitor and report S.M.A.R.T. information will function only under an administrator account. BIOS and Windows ( Windows Vista and later) may detect S.M.A.R.T. status of hard disk drives and solid state drives, and give a prompt if the S.M.A.R.T. status is bad.
Resource Monitor, a utility in Windows Vista and later, displays information about the use of hardware (CPU, memory, disk, and network) and software (file handles and modules) resources in real time. [1] Users can launch Resource Monitor by executing resmon.exe (perfmon.exe in Windows Vista).
Here, a processor may be a (single-core) CPU or one core in a multi-core CPU. Example: A software application executed on a four-core processor creates four Unix processes. If each process is able to execute on a separate processor core, computation proceeds on four processor cores simultaneously.
Advancing to subleaf 1 (by making another call to CPUID with EAX=Bh and ECX=1) could for instance return 201h in ECX, meaning that this is a core-type level, and 4 in EBX because there are 4 logical processors in the package; EAX returned could be any value greater than 3, because it so happens that bit number 2 is used to identify the core in ...
