Torch Tensor Parallelism FAQs

Question 1

When should I use this Claude Code skill?

Accepted Answer

Use this skill when you are developing large-scale neural networks that require model parallelism. It is particularly useful for implementing custom distributed layers, debugging gradient flow in sharded weights, or managing torch.distributed communication patterns like all-gather and all-reduce.

Question 2

What does the Torch Tensor Parallelism skill do?

Accepted Answer

This skill enhances Claude's ability to implement distributed tensor-parallel linear layers in PyTorch. It provides specific guidance on ColumnParallelLinear and RowParallelLinear patterns, weight sharding, and bias handling for models that exceed single-device memory limits.

Question 3

Does it help with common distributed training pitfalls?

Accepted Answer

Yes, it provides strategies to avoid critical issues like truncated file writes during implementation, wrong weight splitting dimensions, and 'bias duplication' which can accidentally multiply bias values by the world size during all-reduce operations.

Question 4

What specific implementation patterns are included?

Accepted Answer

The skill covers Column Parallelism (splitting along output dimensions) and Row Parallelism (splitting along input dimensions). It includes logic for properly sharding weights, managing partitioned inputs, and ensuring correct gradient paths across multiple ranks.

Question 5

How does this skill improve my ML development workflow?

Accepted Answer

It introduces a 'Verify Before Implementing' workflow that includes manual tracing with numeric examples and shape verification tables. This prevents common distributed computing errors, such as dimension mismatches or incorrect bias replication, before you even run your tests.
