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- Real program
- word processing software
- tool software of CDA
- user's application software (i.e.: MIS)
- Microbenchmark
- Designed to measure the performance of a very small and specific piece of code.
- 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
- 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
- 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.
- I/O benchmarks
- Database benchmarks: to measure the throughput and response times of database management systems (DBMS')
- Parallel benchmarks: used on machines with multiple processors or systems consisting of multiple machines
