What problem does it solve?

Parallelized codebase analysis enables scalable, structured examination of large repositories by splitting workloads into independent chunks, analyzing them in parallel, and synthesizing findings with a central reducer.

Core Features & Use Cases

  • Distributed chunking and parallel mapping for large-recompute tasks.
  • Cross-chunk validation and deduplication to produce a consistent ReductionResult.
  • Suitable for bulk code analysis, architectural investigations, and large-scale audits.

Quick Start

Run map-reduce on a codebase to distribute the workload, spawn mapper agents for chunks, and synthesize results with a single reducer.

FAQPage Schema
How do I analyze a large codebase in parallel without missing cross-cutting concerns?

Parallelized codebase analysis splits the repository into chunks and processes them with independent mapper agents. A central reducer then synthesizes findings, performing cross-chunk validation and deduplication to maintain consistency across the entire audit.

When do I need parallel processing for code analysis and architectural investigations?

Parallel processing for code analysis is needed when scaling to large repositories for bulk audits or architectural investigations. It distributes independent chunks to mapper agents, synthesizing results to manage cross-cutting concerns efficiently.

What is the best way to deduplicate code analysis findings across multiple chunks?

The best way to deduplicate code analysis findings is using a central reducer during cross-chunk synthesis. After independent mappers analyze distributed chunks, the reducer validates findings and removes duplicates, producing a consistent ReductionResult for auditing.

Can I use map-reduce for bulk code analysis and large-scale repository audits?

Yes, you can use this parallelized code analysis approach for bulk audits. It orchestrates end-to-end by spawning independent mappers per chunk and a reducer for cross-chunk validation, outputting a ReductionResult suitable for auditing and automation.

How do I scale code analysis to large repositories without losing context?

Scale code analysis by distributing workloads into independent chunks processed by parallel mappers. Cross-chunk validation and a central reducer synthesize findings, ensuring context is preserved and validated across chunks for a consistent ReductionResult.
