Parallel simulation of high-dimensional American option pricing based on CPU versus MIC
Summary
American option pricing is a high-dimensional problem, and its computational challenges have attracted significant attention. We examine this problem using a stochastic mesh method enhanced with bias reduction within the classic Black–Scholes framework. We present Many Integrated Core (MIC) parallelization and acceleration techniques, which result in significant numerical acceleration for large-scale simulations. In particular, we observe speed-ups of 21-fold and 28-fold for CPU and MIC, respectively, over conventional means. Convergence performance is also examined. Copyright © 2014 John Wiley & Sons, Ltd.
