  2. Fair-share scheduling - Wikipedia

    en.wikipedia.org/wiki/Fair-share_scheduling

    On the other hand, if a new user starts a process on the system, the scheduler will reapportion the available CPU cycles such that each user gets 20% of the whole (100% / 5 = 20%). Another layer of abstraction allows us to partition users into groups, and apply the fair share algorithm to the groups as well.

  3. Load (computing) - Wikipedia

    en.wikipedia.org/wiki/Load_(computing)

    The reason CPU queue length did better is probably because when a host is heavily loaded, its CPU utilization is likely to be close to 100%, and it is unable to reflect the exact load level of the utilization. In contrast, CPU queue lengths can directly reflect the amount of load on a CPU.

  4. Task Manager (Windows) - Wikipedia

    en.wikipedia.org/wiki/Task_Manager_(Windows)

    Task Manager, previously known as Windows Task Manager, is a task manager, system monitor, and startup manager included with Microsoft Windows systems. It provides information about computer performance and running software, including names of running processes, CPU and GPU load, commit charge, I/O details, logged-in users, and Windows services.

  5. Spinlock - Wikipedia

    en.wikipedia.org/wiki/Spinlock

    To reduce inter-CPU bus traffic, code trying to acquire a lock should loop reading without trying to write anything until it reads a changed value. Because of MESI caching protocols, this causes the cache line for the lock to become "Shared"; then there is remarkably no bus traffic while a CPU waits for the lock. This optimization is effective ...

  6. Hardware stress test - Wikipedia

    en.wikipedia.org/wiki/Hardware_stress_test

    Stress testing a CPU over the course of 24 hours at 100% load is, in most cases, sufficient to determine that the CPU will function correctly in normal usage scenarios such as in a desktop computer, where CPU usage typically fluctuates at low levels (50% and under).

  7. CPU-bound - Wikipedia

    en.wikipedia.org/wiki/CPU-bound

    The term can also refer to the condition a computer running such a workload is in, in which its processor utilization is high, perhaps at 100% usage for many seconds or minutes, and interrupts generated by peripherals may be processed slowly or be indefinitely delayed. [citation needed]

  8. PDF - Wikipedia

    en.wikipedia.org/wiki/PDF

    PDF 2.0 defines 256-bit AES encryption as the standard for PDF 2.0 files. The PDF Reference also defines ways that third parties can define their own encryption systems for PDF. PDF files may be digitally signed, to provide secure authentication; complete details on implementing digital signatures in PDF are provided in ISO 32000-2.

  9. Benchmark (computing) - Wikipedia

    en.wikipedia.org/wiki/Benchmark_(computing)

    A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
