Instructions (Linux Version of This Program)

Build dependencies include:

  1. The Boost Library Collection (MINIMUM version 1.83 required)

  2. GNU Compiler Collection

  3. CMake minimum version 3.18 (ONLY if you want to run the program with Microsoft mimalloc as memory allocator)

Open a terminal interface and run:

  • make run to run program
  • make run_mimalloc to run program with Microsoft mimalloc as memory allocator
  • make run_tests to run unit tests for SeqDFS implementation
  • NOTE: if running program with input size of vertices 15000 or larger, MUST run ulimit -s unlimited within the terminal before running the actual program or the program will segfault due to default stack size limits; make run takes care of this for you :D

Note: only Linux distributions are supported for now on this main branch.

TODO

  1. Add more detailed comments

  2. Add more details in this README

  3. Add more unit tests

  4. Add in makefile option to run program with Microsoft mimalloc as memory allocator, since I've noticed improved graph reordering speeds using mimalloc to override the default memory allocator. Done on 6/1/24 :)
