SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sparse-quantization on MindSpore within vLLM-MindSpore often lacks a clear loading path, causing integration friction for 310P devices.

Core Features & Use Cases

  • Supports W8A8SC sparse-quantized models and rank-based weight layout loading.
  • Enforces 310P-only execution for sparse paths, with explicit error handling on non-310P devices.
  • Provides end-to-end guidance for weight loading, deq_scale handling, and insertion into Quant Linear Sparse layers.
  • Useful for developers integrating MindSpore sparse quantization into vLLM inference workflows.

Quick Start

Place the sparse-quantized weights under the rank_* directory and initialize the loader to start inference.

FAQPage Schema
How do I load W8A8SC sparse-quantized models in vLLM-MindSpore?

To load W8A8SC sparse-quantized models in vLLM-MindSpore, place weights under the rank_* directory and initialize the loader to switch load_format to sparse_quant for proper inference.

Can I use sparse-quantization for MindSpore inference on non-310P devices?

No, sparse-quantization for MindSpore enforces 310P-only execution for sparse paths. Attempting to run on non-310P devices triggers explicit error handling and stops the loading process.

How does vLLM-MindSpore handle deq_scale conversion during sparse weight loading?

vLLM-MindSpore handles deq_scale conversion by validating weight and index naming, then applying rank-based weight layout loading and integration into QuantLinearSparse layers.

What is the correct weight directory layout for MindSpore sparse quantization models?

The correct weight directory layout for MindSpore sparse quantization models requires placing sparse-quantized weights into rank_* directories to enable proper rank-based or split loader detection.

Why does vLLM-MindSpore fail to detect is_sparse_quantization on my model?

vLLM-MindSpore fails to detect is_sparse_quantization when weight and index naming validations are not met, preventing the load_format from automatically switching to sparse_quant.

What is sparse-quantization in MindSpore used for?

Sparse-quantization in MindSpore is used to load and adapt W8A8SC quantized models within vLLM inference workflows, ensuring proper sparse configuration detection and weight layout validation on 310P devices.
