PARSEC* 3.0 中的多线程代码优化: BlackScholes

The Black-Scholes benchmark is a one of the 13 benchmarks in the PARSEC. This benchmark does option pricing with Black-Scholes Partial Differential Equation (PDE). The Black-Scholes equation is a differential equation that describes how, under a certain set of assumptions, the value of an option changes as the price of the underlying asset changes. Based on this formula, one can compute the...

案例研究: 使用分布式优化框架在 Monte Carlo 欧式期权方面实现高级性能

1. 简介

Monte Carlo 使用统计计算方法解决复杂的科学计算问题。 它创新地使用随机数字模拟一个问题输入结果的不确定性,并通过处理重复的参数抽样获得一个确定的结果和解决一些以其他方式无法解决的问题。 该方法最早起源于上世纪 40 年代末,由参与“曼哈顿”计划的核物理学家们率先提出。 并采用摩纳哥最大的赌城 Monte Carlo 来命名。

无需控制 NUMA 共享内存策略即可在基于 NUMA 的 Nehalem-EX 系统上获得较高性能

简介

默认在 Nehalem-EX 上执行的传统 MKL 性能测试中有很多 MKL LAPACK 函数的性能都较低,尤其是 DGETRF。经检测发现,同样的系统在 Linux 下使用诸如 numactll 之类的实用程序(即控制 NUMA 共享内存策略)性能将获得显著提升,即用以下方式启动应用:
