Linpack Benchmark The LINPACK Benchmarks are a measure of a system's floating point computing power. 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. The solution is obtained by Gaussian elimination with partial pivoting, with 2/3·N3 + 2·N2 floating point operations. The result is reported in millions of floating point operations per second (MFLOP/s, sometimes simply called FLOPS). Results. Mflop/s: Millions of floating point operations per second. A floating point operation here is a floating point addition or a floating point multiplication with 64 bit operands. For this problem there are 2/3 n^3 + n^2 floating point operations. Time: The time in seconds to solve the problem, Ax=b. Norm Res: A check is made to show that the computed solution is correct. The test is based on || Ax - b || / ( || A || || x || eps) where eps is described below. The Norm Res should be about O(1) in size. If this quantity is much larger than 1, the solution is probably incorrect. Precision: 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. ## Key features - Measures floating-point computing power - Solves dense linear equations - Reports MFLOP/s - Checks solution accuracy - Determines relative machine precision ## Recent user reviews (10 of 47) All indexed reviews: https://appshunter.io/ios/app/linpack/id380883195/reviews.md ### 5/5 — Лаконично *2025-06-17, version 1.5.1* Разработчик с большой буквы!

Linpack measures a system's floating-point computing power by solving dense linear equations. The result is reported in millions of floating-point operations per second (MFLOP/s). ### How accurate is Linpack's solution? Linpack includes a 'Norm Res' check to verify the computed solution's correctness. A Norm Res value around O(1) indicates a probably correct solution. ### What is 'Precision' in Linpack? Precision in Linpack refers to the relative machine precision, typically the smallest positive number such that fl(1.0 - eps) < 1.0, where fl is the computed value. ### Is Linpack available on Android? Based on the provided data, Linpack is available for iPhone, iPad, and iPod. Platform availability for Android is not specified. ### How often is Linpack updated? The latest version of Linpack is 1.5.1, last updated on September 15, 2017. Update frequency is not detailed beyond this. ### What is the age rating for Linpack?
