Hyperspectral imaging parallelization with different programming models such as OpenMP, SYCL or Kokkos
To run the code, you will need to install the following dependencies beforehand:
Up till this point, you should be able to run the Sequential, OpenMP and SYCL(on CPU and Intel GPU) codes.
To run with Kokkos implementation you should install Kokkos and Kokkos Kernels libraries. The versions tested were:
Since the Kokkos implementation were thought to run under CPU, NVIDIA GPU and Intel GPU, we greatly recommend you to create two builds of both Kokkos and Kokkos Kernels. The first one could run under CUDA (nvcc) supporting CPU under OpenMP and NVIDIA GPU under CUDA. The second build should support Intel GPUs using oneAPI SYCL as backend.
To enable CUDA GPU support for running with OpenMP, SYCL, and Kokkos, you will need to install the following:
Additionally for SYCL, you will require:
You first need to download the repository:
> git clone https://github.com/artecs-group/hyperspectral_imaging_parallelization > cd hyperspectral_imaging_parallelization > git checkout develop
Now, set the environment variables for the standalon compiler, Kokkos or oneAPI toolkit. In the case of oneAPI:
> source path/to/oneapi/setvars.sh
To build the project you can use the following variables to specify in which device you want to run and what programmin model to use.
Variable Description Values Default IMPL Selects the implementation to run. sequential, sycl, openmp, kokkos non-default DEVICE Selects the device whre to run the code. cpu, igpu (Intel GPU), ngpu (NVIDIA GPU) cpu PDEBUG Used to show debug info during the execution. yes, no no KOKKOS_INSTALL_DIR Path where the user had installed Kokkos path /opt/kokkos/build/ KOKKOS_KERNELS_INSTALL_DIR Path where the user had installed Kokkos Kernels path /opt/kokkos-kernels/buildThen, to build and run the code in sequential mode for the CPU:
> mkdir build > cd build > cmake .. -DCMAKE_CXX_COMPILER=icpx -DIMPL=sequential > make > make run
NOTE: just for sequential, sycl, openmp, you must include the following flag "-DCMAKE_CXX_COMPILER=icpx"
In order to execute with Kokkos framework, you have to set where Kokkos is installed, e.g.:
> mkdir build > cd build > cmake .. -DIMPL=kokkos -DKOKKOS_INSTALL_DIR=/opt/kokkos/build -DKOKKOS_KERNELS_INSTALL_DIR=/opt/kokkos-kernels/build > make > make run
