SCOREC EnGPar

EnGPar, N-Graph Partitioning, is a set of C/C++ libraries for partitioning relational data structures using a parallel graph structure to represent the data.

Repository Layout

• AGI: APIs for the graph structure, N-Graph.
• interfaces: Extensions of the N-Graph for certain data structures.
• Zoltan: Partitioning methods utilizing Zoltan
• partition: Diffusive load balancing routines
• test: A set of tests to utilize the features of EnGPar

Getting started

• Dependencies: CMake, MPI, PCU (can be grabbed from SCOREC Core)
• Configuration: two example configuration files are provided in the EnGPar directory minimal_config.sh and config.sh. The first has the minimum requirements to setup a directory while the second lists the specific flags to turn on and off the various portions of EnGPar.
• Testing: After building the code, the test directory will have several tests and standalone executables that use the different functionalities of EnGPar.
• Calling EnGPar from your application

End-user Build

Edit minimal_config.sh and set the path to the PUMI install directory via the SCOREC_PREFIX variable.

mkdir build
../minimal_config.sh
make

Developer Build

Setup the test mesh and graph repos via submodules

git submodule init
git submodule update

Edit config.sh and set the path to the PUMI install directory via the SCOREC_PREFIX variable.

mkdir build
../config.sh
make
ctest
