Livermore loops (also known as the Livermore Fortran kernels or LFK) is a benchmark for parallel computers. It was created by Francis H. McMahon from scientific source code run on computers at Lawrence Livermore National Laboratory. It consists of 24 do loops, some of which can be vectorized, and some of which cannot. The benchmark was published in 1986 in Livermore fortran kernels: A computer test of numerical performance range. The Livermore loops were originally written in Fortran, but have since been ported to many programming languages. Each loop carries out a different mathematical kernel.Those kernels are: * hydrodynamics fragment * incomplete Cholesky conjugate gradient * inner product * banded linear systems solution * tridiagonal linear systems solution * general linear recurrence equations * equation of state fragment * alternating direction * * * first sum * first difference * 2-D particle in a cell * 1-D particle in a cell * casual Fortran * Monte Carlo search * implicit * 2-D explicit hydrodynamics fragment * general linear recurrence equations * discrete * * Planckian distribution * 2-D implicit hydrodynamics fragment * location of a first array minimum.

McMahon從勞倫斯利弗莫爾國家實驗室的計算機上運行的科學源代碼創建的。它由24個循環組成，其中一些可以被矢量化，而另一些不能。 該基準於1986年發佈为《利弗莫爾Fortran核：一種數学性能的計算機測試》。 利弗莫爾循環最初是用Fortran編寫的，但後來被移植到許多編程語言中。 每個循環執行一個數學核。這些核有： * 流体力学 * 不完全的楚列斯基共轭梯度法 * 内积 * 帶狀線性系統法 * 三對角線性系統法 * 一般线性微分方程 * 状态方程 * 交替方向 * * * 一阶和 * 一阶差分 * 2-D单元格粒子 * 1-D单元格粒子 * 任意Fortran * 蒙地卡羅搜索 * 隱式條件計算 * 二维显式流体力学计算 * 离散 * 矩陣-矩陣转置 * 普朗克定律 * 二维隐式流体力学计算 * 数组中最小值的第一个位置 (zh) |
