Betweenness centrality (BC) on CPU

CPU implementation for BC on weighted graph Contributor: Hang Liu (asherliu@gwu.edu)

---

Environment requirement:

g++, openmp

Graph Converter

Currently, we support converting a graph from matrix based text format. (credit to Yang Hu)

• Source code of converter is in ./converter folder
• Compile: g++ converter.cpp -o converter
• Execution: ./converter /path/to/matrix_graph.txt (please make sure there is no blanket lines in this file)
• You will get four files: beg.bin, csr.bin, weight.bin and degree.bin.
• The former three files are exactly the files required by CPU BC execution
