TaskGroup Class Reference

A class that manages the distribution and execution of tasks in parallel using the MPI library. The TaskGroup class is responsible for managing the distribution and execution of tasks in parallel across multiple MPI processes. It provides methods for determining the number of tasks to be executed by each process, as well as methods for executing and communicating task-related data between processes. More...
