Parallel Circulant Embedding

ParaCirce stands for Parallel Circulant Embedding. It is a library aimed at generating 2D and 3D stationary Gaussian Random Fields (GRF). The algorithm used is based on the Circulant Embedding method, written in C++17 and parallelized with MPI.

It features:

• Several correlation functions

• Anisotropic correlation

• Distributed memory parallelization for optimal performances on large clusters

• Reproductibility, thanks to the pseudo-random numbers generator RngStream.

• Complete Independance of the Monte-Carlo runs.

• Acceleration of the padding computation.
