Use this package to benchmark your SMP machine. Intel provides optimized versions of the LINPACK benchmarks to help you obtain high LINPACK benchmark results on your genuine Intel processor systems more easily than with the High Performance Linpack (HPL) benchmark. LINPACK, the library, which has been expanded upon by the LAPACK library. The benchmark solves 'a (random) dense linear system in double precision (64 bits) arithmetic on distributed-memory computers.' As it is well-tested, and kept updated, it also makes a good example case of.
MP LINPACK, which is a distributed memory version of the same benchmark. High Performance Linpack (HPL) is a portable implementation of the standard Linpack benchmark, used in TOP500 ranking determination. This is a shared-memory (SMP) implementation which runs on a single platform. It uses partial pivoting to assure the accuracy of the results.ĭo not use this benchmark to report LINPACK 100 performance because that is a compiled-code only benchmark. The generalization is in the number of equations ( N) it can solve, which is not limited to 1000. It solves a dense ( real*8) system of linear equations ( Ax=b), measures the amount of time it takes to factor and solve the system, converts that time into a performance rate, and tests the results for accuracy. Intel® Optimized LINPACK Benchmark is a generalization of the LINPACK 1000 benchmark.
