Compute PageRank on large graphs with off-the-shelf hardware.

Project description

danker - Compute PageRank on large graphs with off-the-shelf hardware.

  • Standalone with any input graph:

    $ pip install danker
    $ python -m danker -h
       usage: python -m danker [-h] [-r RIGHT_SORTED] [-p OUTPUT_PRECISION] [-i]
                               left_sorted damping iterations start_value

       positional arguments:
         left_sorted           A two-column, tab-separated file sorted by the left
                               column.
         damping               PageRank damping factor(between 0 and 1).
         iterations            Number of PageRank iterations (>0).
         start_value           PageRank starting value (>0).
    
       optional arguments:
         -h, --help            show this help message and exit
         -r RIGHT_SORTED, --right_sorted RIGHT_SORTED
                               The same file as left_sorted but sorted by the right
                               column.
         -p OUTPUT_PRECISION, --output_precision OUTPUT_PRECISION
                               Number of places after the decimal point.
         -i, --int_only        All nodes are integers (flag)
    
    $ wget https://raw.githubusercontent.com/athalhammer/danker/master/test/graphs/test.links
    $ python3 -m danker test.links 0.85 30 1
