Triumvirate 0.1.1

Three-point clustering measurements in large-scale structure analyses.

Three-Point Clustering Measurements in LSS

Triumvirate is a Python/C++ software package for measuring three-point (and two-point) clustering statistics in large-scale structure (LSS) cosmological analyses.

Documentation

Comprehensive documentation including the scientific background, installation instructions, tutorials and API reference can be found at triumvirate.readthedocs.io.

Installation

Python package

Triumvirate as a Python package is distributed through PyPI and conda. Instructions for installation can be found on the Installation page in the documentation.

C++ library & program

Triumvirate as either a static library or a binary executable can be built using make. Instructions for compilation can be found on the Installation page in the documentation.

Development mode

Both the Python package and the C++ library/program can be set up in development mode with make, provided that dependency requirements are satisfied (GSL and FFTW3 libraries are mandatory while an OpenMP library is optional).

First git clone the desired branch/release from the GitHub repository and change into the repository directory path:

$ git clone [e-mail]:MikeSWang/Triumvirate.git --branch <branch-or-release>
$ cd Triumvirate

Then, execute in terminal:

$ make clean
$ make [py|cpp]install [useomp=(true|1)]

where cpplibinstall or cppappbuild respectively builds the C++ static library or binary executable only, cppinstall builds both, pyinstall builds the Python package only, and install builds all of the above. To enable OpenMP parallelisation, append useomp=true or useomp=1 to the end of the second line as shown above.

Note

The latest release is on the main branch. The default Makefile (located at the repository directory root) should work in most build environments, but may need to be modified as appropriate.

Note

See the Installation page in the documentation for more details about dependency requirements.

Warning

Ensure your C++ compiler used supports OpenMP and is configured accordingly. The default Makefile (located at the repository directory root) assumes the GCC compiler and OpenMP library. See the Installation page in the documentation for more details.

Note

Pass option -j[N] -O to make to run multiple concurrent jobs for parallel building (optional parameter N is the number of parallel jobs; see GNU Make Manual).
