Gpu Document Processing

This separation ensures:

• API keys stay outside the sandbox (security)
• Agent state persists independently of processing jobs
• Processing can be parallelized across documents
• Cost-efficient: GPU used only during processing, not during reasoning

Capabilities

PDF Text Extraction

Extract text content from PDF documents with layout preservation:

• Headers, paragraphs, lists, and tables detected separately
• Page numbers and section boundaries preserved
• Multi-column layout handling

Tabular Data Extraction

Extract tables from documents into structured formats:

• PDF tables to CSV/DataFrames using GPU-accelerated parsing
• Automatic column type detection
• Handles merged cells and multi-row headers

Document Chunking

Split large documents into meaningful chunks for analysis:

• Semantic chunking (by topic/section boundaries)
• Fixed-size chunking with overlap for embedding
• Configurable chunk sizes (default: 512 tokens)

Embedding Generation

Generate vector embeddings for document chunks:

• Uses NVIDIA NeMo Retriever NIM for GPU-accelerated embedding
• Supports batch processing for large document sets
• Compatible with standard vector stores (Milvus, ChromaDB)

Workflow

1. Receive document reference from the orchestrator
2. Determine processing type (extraction, analysis, embedding)
3. Send to GPU sandbox for processing
4. Collect structured results (text, tables, embeddings)
5. Write findings to /shared/ for the orchestrator to synthesize

Processing Large Document Collections

For multiple documents:

1. Process documents in parallel batches (3-5 concurrent)
2. Extract key metadata first (title, date, author, page count)
3. Generate per-document summaries
4. Cross-reference findings across documents
5. Write consolidated findings with per-document citations

Output Format

When reporting document processing results:

• Include document metadata (filename, pages, size)
• Structure extracted content by section/chapter
• Format tables as markdown tables
• Include page references for all extracted content
• Note any extraction quality issues (scanned images, corrupted pages)

Integration with NVIDIA NIM

For production deployments, GPU document processing can leverage:

• NVIDIA NeMo Retriever: GPU-accelerated embedding and retrieval
• NVIDIA RAPIDS cuDF: Tabular data processing from extracted tables
• NVIDIA Triton: Scalable inference for document classification models

See NVIDIA's NIM documentation for self-hosted deployment options.
