# Automatic Parallelization

Once the existing sequential code has been analyzed and opportunities for parallelization have been identified, Parallel AI employs its core feature: automatic parallelization. This again follows a 3 stage process:



**Phase 1 - Task Identification:** The system identifies independent tasks within the code that can be executed in parallel. This is based on the absence of data dependencies that would otherwise require tasks to be performed in a specific sequence.

**Phase 2 - Code Transformation:** Parallel AI transforms these independent tasks into a format that can be executed across multiple processing units. This transformation involves converting standard loops and operations into parallel constructs, such as parallel loops or concurrent function calls.

**Phase 3 - Algorithmic Optimization:** Advanced optimization algorithms refine the transformed code to maximize efficiency. This includes optimizing memory usage, minimizing communication overhead between processing units, and balancing load across the available hardware resources.



Now that the code has been transformed into the optimal form for parallel processing it is executed using Parallel AI’s proprietary execution model.
