gcc 4.4.7 or 4.8.5

CUDA 5.5, 6.0, 6.5, 7.0, 7.5 (tested and works)

make

Type: "./gpu_ibfs.bin" it will show you what is needed.

You could use the code from "tuple_text_to_binary_csr" folder to convert a edge list (text formated) graph into CSR files (binary), e.g., if you have a text file called "test.txt", it will convert it into "test.txt_beg_pos.bin" and "test.txt_csr.bin". You will need these two files to run gpu_ibfs.

• Compile: make
• To execute: type "./text_to_bin", it will show you what is needed
• Basically, you could download a tuple list file from snap. Afterwards, you could use this converter to convert the edge list into CSR format.

For example:

• Download https://snap.stanford.edu/data/com-Orkut.html file. unzip it.
• ./text_to_bin.bin soc-orkut.mtx 1 2(the number may change due to how many lines are not edges)
• You will get soc-orkut.mtx_beg_pos.bin and soc-orkut.mtx_csr.bin.
• You could use these two files to run enterprise.

• Centrality computation, e.g., Betweenness centrality, Closeness centrality.
• Multi-source shortest path, All-pairs shortest path.
• Reachiability index construction.
• In short, any applications, which need to run multiple traversals on the same graph, should benefit
