SPECfp

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 as SPECfp89. Later it was replaced by SPECfp92, then SPECfp95, then SPECfp2000, and finally SPECfp2006.

Background

SPEC CPU2006 is a suite of benchmark applications designed to test the CPU performance. The suite is composed of two sets of tests. The first being CINT (aka SPECint) which is for evaluating the CPU performance in integer operations. The second set is CFP (aka SPECfp) which is for evaluating the CPU floating point operations performance.

The benchmark applications are programs that perform a strict set of operation that simulate real time situations, such as physical simulations, 3D graphics, and image processing. These applications are written in different programming languages, C, C++ and Fortran. Many SPECfp benchmark applications are derived from applications that are freely available to the public and each application is assigned a weight based on its importance.
