This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from benchmark software without restrictions. The relative machine precision usually the smallest positive number such that fl( 1.0 - eps ) < 1.0, where fl denotes the computed value and eps is the relative machine precision. Linpack Xtreme 1.1.3 on 32-bit and 64-bit PCs. If this quantity is much larger than 1, the solution is probably incorrect. linpack download UpdateStar - HPL is a software package that solves a (random)dense linear system in double precision (64-bit)arithmetic on. The Norm Res should be about O(1) in size. The test is based on || Ax - b || / ( || A || || x || eps) where eps is described below. The time in seconds to solve the problem, Ax=b.Ī check is made to show that the computed solution is correct. For this problem there are 2/3 n^3 + n^2 floating point operations.

A floating point operation here is a floating point addition or a floating point multiplication with 64 bit operands. Millions of floating point operations per second. The result is reported in millions of floating point operations per second (MFLOP/s, sometimes simply called FLOPS). The solution is obtained by Gaussian elimination with partial pivoting, with 2/3 Introduced by Jack Dongarra, they measure how fast a computer solves a dense N by N system of linear equations Ax = b, which is a common task in engineering.

This excludes the use of a fast matrix multiply algorithm like "Strassen's Method" or algorithms which compute a solution in a precision lower than full precision (64 bit floating point arithmetic) and refine the solution using an iterative approach.The LINPACK Benchmarks are a measure of a system's floating point computing power. In particular, the operation count for the algorithm must be 2/3 n^3 + O(n^2) double precision floating point operations. In an attempt to obtain uniformity across all computers in performance reporting, the algorithm used in solving the system of equations in the benchmark procedure must conform to LU factorization with partial pivoting. These numbers together with the theoretical peak performance Rpeak are the numbers given in the TOP500. It does, however, reflect the performance of a dedicated system for solving a dense system of linear equations. Since the problem is very regular, the performance achieved is quite high, and the performance numbers give a good correction of peak performance.īy measuring the actual performance for different problem sizes n, a user can get not only the maximal achieved performance Rmax for the problem size Nmax but also the problem size N1/2 where half of the performance Rmax is achieved. This performance does not reflect the overall performance of a given system, as no single number ever can. For the TOP500, we used that version of the benchmark that allows the user to scale the size of the problem and to optimize the software in order to achieve the best performance for a given machine. The benchmark used in the LINPACK Benchmark is to solve a dense system of linear equations.

A detailed description and frequently asked questions can be found: Ī parallel implementation of the Linpack benchmark and instructions on how to run it can be found at. The LINPACK Benchmark was introduced by Jack Dongarra. LINPACK was chosen because it is widely used and performance numbers are available for almost all relevant systems. Linpack Xtreme is a small console front-end with the latest build of Linpack (Intel Math Kernel Library Benchmarks 2018.3.011). As a yardstick of performance we are using the `best' performance as measured by the LINPACK Benchmark.
