Scalability of an MPI4PY implementation of a 2D correlation code versus MPI

Raison Frederic

A 2D correlation code has been developed based on MPI4PY in order to perform statistical analysis of galaxy surveys. Input data have been produced by the Millennium cosmological simulation. Two algorithms have been implemented: the first one considers point-like locations of the sources along the redshift axis. The other algorithm is using the probability density function along the redshift direction. We ran the code on a large cluster and compared its scalability to an MPI implementation.
