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. The term 'benchmark' is also mostly utilized for the purposes of elaborately-designed benchmarking programs themselves.

Types of benchmarks
  1. Real program
    • word processing software
    • tool software of CDA
    • user's application software (i.e.: MIS)
  2. Microbenchmark
    • Designed to measure the performance of a very small and specific piece of code.
  3. Kernel
    • contains key codes
    • normally abstracted from actual program
    • popular kernel: Livermore loop
    • linpack benchmark (contains basic linear algebra subroutine written in FORTRAN language)
    • results are represented in MFLOPS
  4. Component Benchmark/ micro-benchmark
    • programs designed to measure performance of a computer's basic components
    • automatic detection of computer's hardware parameters like number of registers, cache size, memory latency
  5. Synthetic Benchmark
    • Procedure for programming synthetic benchmark:
      • take statistics of all types of operations from many application programs
      • get proportion of each operation
      • write program based on the proportion above
    • Types of Synthetic Benchmark are:
    • These were the first general purpose industry standard computer benchmarks. They do not necessarily obtain high scores on modern pipelined computers.
  6. I/O benchmarks
  7. Database benchmarks: to measure the throughput and response times of database management systems (DBMS')
  8. Parallel benchmarks: used on machines with multiple processors or systems consisting of multiple machines
Common benchmarksIndustry standard (audited and verifiable
Open source benchmarks
  • DEISA Benchmark Suite: scientific HPC applications benchmark
  • Dhrystone: integer arithmetic performance
  • Fhourstones: an integer benchmark

  • Iometer: I/O subsystem measurement and characterization tool for single and clustered systems.
  • Linpack, traditionally used to measure FLOPS
  • LAPACK[citation needed]
  • Livermore loops
  • NAS parallel benchmarks
