Building from Source

Ubuntu

git clone https://github.com/rapastranac/gempba.git
cd gempba
mkdir build && cd build
cmake ..
make -j$(nproc)

Windows (MSYS2 / MinGW64)

Open an MSYS2 MinGW64 shell, then:

git clone https://github.com/rapastranac/gempba.git
cd gempba
mkdir build && cd build
cmake -G "MSYS Makefiles" ..
make -j$(nproc)

CMake flags

By default the build enables examples and tests. The available flags are:

Flag	Default	Description
GEMPBA_MULTIPROCESSING	OFF	Enable MPI support
GEMPBA_BUILD_EXAMPLES	ON	Build the example binaries
GEMPBA_BUILD_TESTS	ON	Build the test suite
GEMPBA_DEV_MODE	OFF	Enable developer-only checks
GEMPBA_DEBUG_COMMENTS	OFF	Extra runtime logging

Pass any flag at configure time:

cmake -DGEMPBA_MULTIPROCESSING=ON -DCMAKE_BUILD_TYPE=Release ..

All binaries land in bin/.

Running tests

ctest --output-on-failure

Running examples

After building, the scripts/ directory has ready-to-use launch scripts for each platform.

Linux

Make the script executable if it is not already, then run it from the repo root:

chmod +x scripts/run.sh
./scripts/run.sh

Windows (MSYS2)

The same shell script runs directly from an MSYS2 terminal:

./scripts/run.sh

Open scripts/run.sh to see the available scenarios and uncomment the one you want to run. Other scripts in the same folder cover benchmarking over a single input (run_benchmark.sh) and batch runs over a directory of graph files (run_folder.sh).
