This project is built using cmake, so you will need to install cmake before starting a build.

To build just the base framework:

cd build
cmake <options> ..
make

Cmake build options:

• -DCMAKE_BUILD_TYPE=Debug - Builds the project with asserts, debug logging and debug symbols.
• -DCMAKE_BUILD_TYPE=Test - Builds the project with asserts, debug logging, but without debug symbols.
• -DUSE_OLD_DPDK=ON - Include DPDK support for older (<19.11) versions.
  Optional -DRTE_SDK=<build-location> and -DRTE_TARGET=x86_64-native-linuxapp-gcc can be provided for non standard build locations.
• -DUSE_HSA=ON - Build with HSA support if available. On by default.
• -DUSE_OLD_ROCM=ON - Build for ROCm versions 2.3 or older. Off by default.
• -DUSE_CLOC=ON - For HSA, use cloc.sh to compile .hsaco binaries. Direct toolchain calls are used by default.
• -DUSE_OPENCL=ON - Build with OpenCL support.
• -DUSE_CUDA=ON - Build with CUDA support, requires nvcc
• -DUSE_HDF5=ON and -DHIGHFIVE_PATH=<path> - To enable the HDF5 writer
• -DUSE_AIRSPY=ON - Build the AirSpy producer. Requires libairspy.
• -DUSE_FFTW=ON - Build an FFTW-based F-engine. Requires FFTW3.
• -DUSE_LAPACK=ON - Build stages depending on LAPACK.
• -DBLAZE_PATH=<blaze_path> - Path to BLAZE headers. Required if USE_LAPACK is set.
• -DCOMPILE_DOCS=ON - Build kotekan documentation. Requires doxygen, sphinx (+ sphinx_rtd_theme), and breathe. Note that docs will only compile if explicitly told to, it is not part of the base compile, even when enabled.
• -DUSE_OMP=ON Build stages using OpenMP. This requires a compiler supporting OpenMP (>= 3.0)
• -DOPENSSL_ROOT_DIR=<openssl_root_dir> Only required for non-standard install locations of OpenSSL
• -DWITH_TESTS=ON Build kotekans test library.
• -DWITH_BOOST_TESTS=ON Build C++ unit tests using The Boost Test Framework. pytest-cpp needs to be installed for pytest to find them.
• -DSUPERDEBUG=ON Add extra debugging info and turn off all optimisation to improve coverage.
• -DSANITIZE=ON Turn on extra Clang sanitizers (currently the address sanitizer) for finding issues.

Examples:

To build with OpenCL and debug symbols and logging:

cmake -DUSE_OPENCL=ON -DCMAKE_BUILD_TYPE=Debug ..

To build with CUDA:

cmake -DUSE_CUDA=ON ..

To build with HSA, old DPDK and debug symbols (CHIME):

cmake -DRTE_SDK=/opt/dpdk-stable-16.11.4/ -DRTE_TARGET=x86_64-native-linuxapp-gcc -DUSE_OLD_DPDK=ON -DUSE_HSA=ON -DCMAKE_BUILD_TYPE=Debug ..

To install kotekan (only works on CentOS at the moment):

make install

Using systemd (full install)

To start kotekan

sudo systemctl start kotekan

To stop kotekan

sudo systemctl stop kotekan

To run in debug mode, run from ch_gpu/build/kotekan/

sudo ./kotekan -c <config_file>.yaml

For example:

sudo ./kotekan -c ../../kotekan/kotekan_gpu_replay.yaml

When installed kotekan's config files are located at /etc/kotekan/

If running with no options then kotekan just starts a rest server, and waits for someone to send it a config in json format on port 12048
