  2. Iron law of processor performance - Wikipedia

    en.wikipedia.org/wiki/Iron_law_of_processor...

    Selection of an instruction set architecture affects , whereas is largely determined by the manufacturing technology. Classic Complex Instruction Set Computer (CISC) ISAs optimized I n s t r u c t i o n s P r o g r a m {\displaystyle \mathrm {\tfrac {Instructions}{Program}} } by providing a larger set of more complex CPU instructions .

  3. Roofline model - Wikipedia

    en.wikipedia.org/wiki/Roofline_model

    If, for instance, the considered kernel or application performs far below the roofline, it might be useful to capture other performance ceilings, other than simple peak bandwidth and performance, to better guide the programmer on which optimization to implement, or even to assess the suitability of the architecture used with respect to the ...

  4. LINPACK benchmarks - Wikipedia

    en.wikipedia.org/wiki/LINPACK_benchmarks

    The performance of a computer is a complex issue that depends on many interconnected variables. The performance measured by the LINPACK benchmark consists of the number of 64-bit floating-point operations, generally additions and multiplications, a computer can perform per second, also known as FLOPS. However, a computer's performance when ...

  5. Amdahl's law - Wikipedia

    en.wikipedia.org/wiki/Amdahl's_law

    "the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used". [2] It is named after computer scientist Gene Amdahl, and was presented at the American Federation of Information Processing Societies (AFIPS) Spring Joint Computer Conference in 1967.

  6. Cycles per instruction - Wikipedia

    en.wikipedia.org/wiki/Cycles_per_instruction

    In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. [1] It is the multiplicative inverse of instructions per cycle.

  7. Computer performance - Wikipedia

    en.wikipedia.org/wiki/Computer_performance

    In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:

  8. Gustafson's law - Wikipedia

    en.wikipedia.org/wiki/Gustafson's_law

    — A computer program that processes files from disk. A part of that program may scan the directory of the disk and create a list of files internally in memory. After that, another part of the program passes each file to a separate thread for processing. The part that scans the directory and creates the file list cannot be sped up on a ...

  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.
