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...
