A parallel k-core decomposition (PKC) algorithm on Multicore Platforms for large sparse graphs.
Compiling the program:
$ cd /PKC/ $ make By default, gcc compiler is used. Intel's icc compiler can also be used. To use icc, please change the Makefile to include -openmp flag.
The input to the program is a text file. The file should contain an undirected graph and vertex should start from 0. The first line contains the number of vertices(N) and number of edges(M). Next M lines contain the M edges. Please check the example.txt file for an example graph.
The program can be executed using the following command: $ OMP_NUM_THREADS=p ./pkc.exe graph.txt where, p is the number of threads used and graph.txt is a file containing a sparse graph. By default the number of threads is 1.
If you use PKC, please cite our paper: H. Kabir and K. Madduri, "Parallel k-core Decomposition on Multicore Platforms," in The 2nd IEEE Workshop on Parallel and Distributed Processing for Computational Social Systems (ParSocial 2017), June 2017, to appear.
