Algorithms in This Repo

Cloning

git clone https://github.com/MohsenKoohi/LaganLighter.git --recursive

Updating through pull

  • git pull --recurse-submodules or
  • You may set recursive submodule update globally using git config --global submodule.recurse true and then git pull fetches all updates.

Requirements

  1. The libnuma, openmp, and papi are required.
  2. A gcc with a version greater than 9 are required.
  3. For using ParaGrapher, JDK with a version greater than 15 is required.
  4. unzip, bc, and wget.

Compiling and Executing Code

  • Make sure the requried libraries are accessible through $LD_LIBRARY_PATH.
  • Run make alg... (e.g. make alg1_sapco_sort). This builds the executible file and runs it for the test graph.
  • For identifying input graph and other options, please refer to LaganLighter Documents, Loading Graphs.

How Does LaganLighter Work?

Please refer to LaganLighter Documentation

Supported Graph Types & Loading Graphs

LaganLighter supports reading graphs in text format and in compressed WebGraph format, using ParaGrapher library, particularly:

  • PARAGRAPHER_CSX_WG_400_AP,
  • PARAGRAPHER_CSX_WG_404_AP, and
  • PARAGRAPHER_CSX_WG_800_AP .

Please refer to Graph Loading Documentation.

Processing Multiple Graphs

Please refer to Launcher Script Documentaion.
