Introduction

This is an update of the article Monte Carlo European Option Pricing with RNG Interface for Intel® Xeon Phi™ Coprocessor, which covered the technical details of the Monte Carlo methods and the random number generation with Intel® Math Kernel Library (Intel® MKL). In this article, we discuss the performance of the workload updated for Intel® Xeon® Scalable processors.

Code Changes

This section describes the changes in the source code from the previous version.

The source has been modified to read the input from the user to make the source run across various Intel® Xeon® platforms.

Another change includes a different method for random number stream generation. The new source uses a SIMD-oriented Fast Mersenne Twister pseudorandom number generator for improved performance. The random numbers generated are single precision for both the single- and double-precision versions.  

Code Access

Monte Carlo European Option Pricing for Intel® Xeon® processors is maintained by Nimisha Raut and available under the Intel Sample Source Code License Agreement.

Build and Run Directions

Here are the steps for rebuilding the program:

  1. Install Intel® Parallel Studio on your system.
  2. Untar the MonteCarlo.tar.
  3. Type make to build the binaries for single and double precision.
    • For single precision: MonteCarloInsideBlockingSP.x
    • For double precision: MonteCarloInsideBlockingDP.x

    Where x is abbreviation for the platform as below:

    • avx512 – for Intel Xeon Scalable processors supporting Intel® Advanced Vector Extensions 512 (Intel® AVX-512) instruction set extensions
    • avx2 – for systems supporting Intel® Advanced Vector Extensions 2 instruction set extensions
    • knl - for Intel® Xeon Phi™ processor x200 product family
    • sse4_2 – for systems supporting Intel® Streaming SIMD Extensions 4.2 (Intel® SSE4.2) instruction set extensions
    • scalar - scalar version
  4. Make sure the host machine is powered by Intel Xeon processors.
