SPEC defines a base runtime for each of the 12 benchmark programs. For SPECint2006, that number ranges from 1000 to 3000 seconds. The timed test is run on the system, and the time of the test system is compared to the reference time, and a ratio is computed. That ratio becomes the SPEC INT score for that test.
The actual performance will always be lower than the peak performance. [2] 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 ...
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.
The PCMark test measures overall system performance and returns an official PCMark score. The Lightweight test measures the capabilities of entry level systems unable to run the full PCMark suite. The Entertainment test measures system performance in entertainment, media and gaming scenarios. The Creativity test measures performance in typical ...
CoreMark draws on the strengths that made Dhrystone so resilient - it is small, portable, easy to understand, free, and displays a single number benchmark score. Unlike Dhrystone, CoreMark has specific run and reporting rules, and was designed to avoid the well understood issues that have been cited with Dhrystone .
SPECfp is a computer benchmark designed to test the floating-point performance of a computer. It is managed by the Standard Performance Evaluation Corporation. SPECfp is the floating-point performance testing component of the SPEC CPU testing suit. The first standard SPECfp was released in 1989 [1] as SPECfp89. Later it was replaced by SPECfp92 ...
time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time. [1] timem (Unix) - can be used to determine the wall-clock time, CPU time, and CPU utilization similar to time (Unix) but supports numerous extensions.
The Standard Performance Evaluation Corporation (SPEC) is a non-profit consortium that establishes and maintains standardized benchmarks and performance evaluation tools for new generations of computing systems. SPEC was founded in 1988 and its membership comprises over 120 computer hardware and software vendors, educational institutions ...
