Impala (Multiple Point Simulation)
Project Overview

Impala is a fully parallelized algorithm for multiple point statistics simulation which is both fast and compact in terms of RAM requirement.

Current version (Impala 2.1) has the following features:

  • Uses a hybrid tree-list method allowing to optimize the storage and retrieving of the statistics computed on the training image,
  • Fully parallelized (under the OpenMP and MPI protocols),
  • Proposes new methods for conditioning to existing hard data,
  • Can handle incomplete training images, opening the way to image reconstruction,
  • Offers a wide choice of simulation path strategies,
  • Proposes an Automatic Template Reduction (ATR), to optimize the template size according to the multigrid levels,
  • Embeds a novel algorithm to account for secondary attribute,
  • Can account for non-stationarity, using a-priori expert information,
  • Offers the possibility to respect local or global target proportions.
