The benchmark was run with XCMD='-c4' which runs the benchmark with four contexts. The final marks reflect different groupings of these kernel results' geometric means.

In the example below, each of the kernels is run with three different dataset sizes (small, medium, large) and both single-precision (SP) and double-precision (DP). Here is example output running all of the kernels and computing all of the marks. Out of the box, FPMark can be compiled using the GNU make utility, and for convenience, a PERL script computes all of the summary marks from the dozens of component runs.

Fourier Coefficients ( xp1px) : Numerical analysis routine for calculating series or representing a periodic function by a discrete sum of complex exponentials, also known as (x+1)^x, defined on the interval.

Ray-Tracer ( ray) : A technique for image generation by tracing light path through pixels in an image plane and simulating the effects of its encounters with virtual objects.

Neural Net ( nnet) : A small neural-net inference engine.

LU Decomposition ( lu) : Performs lower-upper matrix decomposition.

They are used to test the computational capabilities of parallel hardware and cover areas such as 2D Particle-in-Cell, Tri-diagonal Elimnation and Planckian Distribution.

Enhanced Livermore Loops ( loops, inner-product) : This one kernel contains two dozen real-world functions extracted from programs used at Lawrence Livermore Labs.

Linear Algebra ( linear_alg) : Derived from Linpack useful for understanding balancing forces in structural engineering, converting between reference frames in relativity, solving differential equations, and understanding rotation and fluid flow, for example.

Fast Fourier Transform ( radix2) : Takes any function and converts it to an equivalent set of sine waves applications such as audio, spectral analysis, and image compression (computed at radix 2).

Horner's Method ( horner) : A method to approximate the roots of a polynomial more information at Wikipedia.

Black-Scholes ( blacks) : A mathematical model for the dynamics of a financial market containing derivative investment instruments.

ArcTan ( atan) : Calculates angles of right triangle by using the ratio of two sides of the triangle to calculate the angle between them.

Each algorithm is run with three different dataset sizes and both single- and double-precision. Here is a list of the algorithms used in FPMark (and the kernel name used in the source code).

To help answer some basic questions, we've writen an introduction to FPMark. RToS, baremetal, and Linux are supported.ДЄll workloads are self-verifying, meaning the expected results are compared against a 'gold standard' generated by IEEE 64-bit precision. The MITH framework requires very little FP library support, and is POSIX-thread compatible (there is also a single-thread version if no threading library is supported). The kernels are grouped into different marks which help summarize performance. It is built on the EEMBC Multi-instance Test Harness (MITH) which allows runtime configuration of the number of contexts or workers to examine the parallel performance of a platform. These permutations reflect a broad range of microcontrollers and platforms.ДЇPMark is multicore-ready. The workloads differ by the floating-point precision: single-precision (SP) and double-precision (DP) and by dataset size (small, medium, large). FPMark solves both of these problems.ДЇPMark consists of a number of kernels which are configured into workloads. Linpack, Nbench, Livermore loops), there hasn't been an effort to standardize the version, or the method by which the tests are run. While several FP benchmarks already exist in general use (i.e. In the same way that CoreMarkВ® was intended to be a вЂњbetter DhrystoneвЂќ, FPMark provides something better than the вЂњsomewhat quirkyвЂќ Whetstone and Linpack. Floating point arithmetic is crucial for embedded applications such as audio, video, DSP, graphics, automotive, and motor control.
