nbodykit 0.1.5

Data analysis of cosmology simulations in parallel.

nbodykit is an open source project and Python package providing a set of algorithms useful in the analysis of cosmological datasets from N-body simulations and large-scale structure surveys.

Driven by the optimism regarding the abundance and availability of large-scale computing resources in the future, the development of nbodykit distinguishes itself from other similar software packages (i.e., nbodyshop, pynbody, yt, xi) by focusing on :

• a unified treatment of simulation and observational datasets by insulating algorithms from data containers

• reducing wall-clock time by scaling to thousands of cores

• deployment and availability on large, super computing facilities

All algorithms are parallel and run with Message Passing Interface (MPI).

For users using the NERSC super-computers, we provide a ready-to-use tarball of nbodykit and its dependencies; see Using nbodykit on NERSC for more details.

Build Status

We perform integrated tests of the code, including all built-in algorithms, in a miniconda environment for Python 2.7 and Python 3.4.
