Description Usage Arguments Value
This function is a simple wrapper around the ANSI C version of the SciMark 2.0 benchmark which is a benchmark for numerical and scientific computing. Concicely performance measurements for the computational kernels Fast Fourier Transformation (FFT), Gauss-Seidel relaxation, Sparse matrix-multiply, Monte Carlo integration and dense LU factorization are computed.
In order to isolate effects of memory hierarchy the problem sizes, e.g.,
the size of the matrix fpr the dense LU matrix factorization, are pretty small.
However, addressing the performance of the memory subsystem is possible by
setting the large
argument to TRUE
.
