Alzheimer Prediction (Deployed Application)

Web application deployment for Alzheimer's detection from MRI images

Documentation

1. Build a Docker image with docker-compose

   docker-compose build --no-cache

2. Run the Docker container with docker-compose

   docker-compose -f docker-compose.yml up

3. Parallelize the application

   • Use gunicorn as a process manager with uvicorn workers to take advantage of multi-core CPUs in production for running multiple processes in parallel.
   • This is achieved in config/gunicorn.py. More specifically:

     workers = int(os.getenv('WEB_CONCURRENCY', multiprocessing.cpu_count() * 2))
     worker_class = os.getenv('WORKER_CLASS', 'uvicorn.workers.UvicornWorker')

   • Example showing parallelization for a CPU with 6 cores and 12 logical processors
