helix-solver

Old project structure and README

All the files of helix-solver present before pl-new-project-structure have been moved to the old directory. Project's components will be gradually moved/copied to the root directory with changes neccessary to make them compliant with the new structure, build system, and conventions.

Documentation

Documetnation is placed in docs directory.

Setup dev environment

• Build docker image with tag helix-solver-docker: docker build -t helix-solver-docker ..
• Run the image in interactive mode: docker run --gpus all --rm -it -v.:/helix/repo -v /usr/local/cuda-12.1:/cuda helix-solver-docker.
• At this point you should have root console like looking like: root@ec333231c56e:/helix/repo# .
• Prepare environment: source prepare_environment.sh.
• Build the app: ./build.sh.
• Obtain spacepoints.root file (e.g. scp it).
• Edit /code/config.json to point to it and run the code: ./build/application/HelixSolver/HelixSolver config.json.

Troubleshooting

SYCL_FEATURE_TEST_EXTRACT Function invoked with incorrect arguments

SYCL feature test compile failed!
compile output is: 
CMake Error at /opt/intel/oneapi/compiler/2023.2.1/linux/IntelSYCL/IntelSYCLConfig.cmake:282 (SYCL_FEATURE_TEST_EXTRACT):
  SYCL_FEATURE_TEST_EXTRACT Function invoked with incorrect arguments for
  function named: SYCL_FEATURE_TEST_EXTRACT
Call Stack (most recent call first):
  CMakeLists.txt:25 (find_package)

If you encounter this error make sure that:

• Cmake uses appropriate compilers (icx for C and icpx for C++), see Unable to use cmake + intel compiler + intel/oneapi-basekit:devel-ubuntu22.04.
• Cuda directory is mounted into the container.
• CUDA is installed on the host machine and accessible from the container. Run nvcc --version.
• $PATH includes path to CUDA.
• $LD_LIBRARY_PATH includes [path to cuda]/lib64
