Passerone in the 2021/2022 A.Y. We implemented and evaluated various\napproaches to the parallelization of the Quadtree image decomposition algorithm, such as CPU-based, CUDA-based and\nmixed approaches.\n\n## Compile\n\nLocally:\n\n```shell\nmkdir build \u0026\u0026 cd build\nconan install --build=missing ..\ncmake -DCMAKE_BUILD_TYPE=Release ..\ncmake --build .\n```\n\nOn the University of Trento's HPC cluster, do this instead:\n\n```shell\nmodule load gcc91\nmodule load cuda-11.1\nmkdir build \u0026\u0026 cd build\nconan install --build=missing ..\n/apps/cmake-3.20.3/bin -DCMAKE_TOOLCHAIN_FILE=../cmake/toolchain-hpc.cmake -DCMAKE_BUILD_TYPE=Release ..\n/apps/cmake-3.20.3/bin --build .\n```\n\n## Usage\n\nOnce the project is built, four apps are produced: `qt-rec-td`, `qt-rec-bu`, `qt-it-gpu`, `qt-it-cpu`.\n\nTo print the usage of an application, do, for example, `./qt-rec-td -h`.\n\n```shell\nUsage: qt-rec [options] \n\nOptional arguments:\n-h --help               shows help message and exits [default: false]\n-v --version            prints version information and exits [default: false]\n--input                 specify the input file [required]\n--detail-threshold      specify the detail threshold [default: 13]\n--no-output-file        suppress the production of the resulting image [default: false]\n--csv                   writes timing information to csv file [default: false]\n```\n\n![Demo](https://github.com/andreastedile/aca/blob/master/demo/result.gif)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandreastedile%2Faca","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fandreastedile%2Faca","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandreastedile%2Faca/lists"}
