# Parallel Code Inputting & Analysis

The first step in the Parallel AI process is the input and analysis of existing sequential code or high-level commands provided by the user to identify opportunities for parallel processing. This works in 3 phases:

**Phase 1 - User Input:** Developers write code using a high-level, Python-like syntax that is designed to be intuitive and easy to understand. This code can represent complex algorithms or routine data processing tasks.

**Phase 2 - Code Parsing:** The Parallel AI system parses the input code to understand its structure, dependencies, and the computational goals it aims to achieve. This parsing step is critical as it lays the groundwork for identifying parallelization opportunities.

**Phase 3 - Dependency Analysis:** The system analyzes data dependencies within the code to identify which parts of the code can be executed in parallel and which parts must be executed sequentially. This involves building a dependency graph that visually maps out the tasks and their dependencies.

With the opportunities for parallel processing now identified, the process moves on to Parallel AI’s core function of automatic parallelization.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://parallel-ai.gitbook.io/parallel-ai/technology/parallel-code-inputting-and-analysis.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
