Installation

Code was developed with Ubuntu 12.04 and greater but should be compatible with other Unix enviroments

Dependencies

Shared memory implementation

• CFITSIO 3.370
• HEALPix 3.11
• MKL or another library for the BLAS/LAPACK routines.

Distributed memory implementation

• CFITSIO 3.370
• HEALPix 3.11
• Elemental 0.84

Input Generation and Testing Scripts

Python scripts are used for creating test data and comparing the results. The following python packages are used:

• numpy
• pyfits
• healpy
• matplotlib

pyfits and healpy are available through pip.

Configuration

Shared memory implementation

After installing the dependencies:

$ cp PATHS.template PATHS

This file is included in the Makefiles for the two implementations, edit it to find your libraries.

Running

Testing implementations against each other

Make sure you you have execute permissions for the the scripts in test/

$ make test_debug
