LINPACK and MP LINPACKBenchmarks 10This chapter describes the Intel® Optimized LINPACK Benchmark for the Linux* OS andIntel® Optimized MP LINPACK Benchmark for Clusters.Intel® Optimized LINPACK Benchmark for Linux OS*Intel® Optimized LINPACK Benchmark is a generalization of the LINPACK 1000 benchmark.It solves a dense (real*8) system of linear equations (Ax=b), measures the amount oftime it takes to factor and solve the system, converts that time into a performance rate,and tests the results for accuracy. The generalization is in the number of equations (N) itcan solve, which is not limited to 1000. It uses partial pivoting to assure the accuracy ofthe results.This benchmark should not be used to report LINPACK 100 performance, as that is acompiled-code only benchmark. This is a shared memory (SMP) implementation whichruns on a single platform and should not be confused with MP LINPACK, which is adistributed memory version of the same benchmark. This benchmark should not beconfused with LINPACK, the library, which has been expanded upon by the LAPACK library.Intel is providing optimized versions of the LINPACK benchmarks to make it easier thanusing HPL for you to obtain high LINPACK benchmark results on your systems based ongenuine Intel® processors. Use this package to benchmark your SMP machine.Additional information on this software as well as other Intel® software performanceproducts is available at http://developer.intel.com/software/products/.ContentsThe Intel Optimized LINPACK Benchmark for Linux* contains the following files, located inthe ./benchmarks/linpack/ subdirectory in the Intel MKL directory (see Table 3-1):10-1
