Codes developed

  • GRaph Made Statistics for Cosmological Inference (GRAMSCI): A big data analytic approach to higher-order correlation function estimation. The code is driven by a custom graph database and a powerful kd-tree implementation. Running in serial, OpenMP, MPI and hybrid parallel schemes. Source code available from:
  • KD-treeStatisticsPackage(Kstat): A fast and efficient framework for computing spatial statistics in a discrete point set. It is based on kd-tree structures for fast nearest neighbour searches and MPI for large scale parallelism. Source code available from:
  • Pseudo Shear Power Spectrum (PS2): This code estimates the galaxy shear power spectrum. It uses at its core the Healpix package for spherical decomposition of discrete data. It works on the full sky and will reconstruct the true power spectrum in the presence of masking. Source code available from:
