Physicsnemo Shard Tensor

Q: What is a Claude Code skill and how does the Physicsnemo Shard Tensor skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Physicsnemo Shard Tensor is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Science & Research category.

Official NVIDIA-authored guidance for PhysicsNeMo ShardTensor domain parallelism — integrate domain parallelism into training/inference scripts (new or existing) with DDP or FSDP2, write and register shard patches to enable new layers/ops, and bootstrap multi-GPU correctness tests. Use when working with ShardTensor, scatter_tensor, domain parallelism, sequence/spatial sharding, ring attention, DeviceMesh + DDP/FSDP2 hybrid parallelism, or physicsnemo.domain_parallel. Do NOT use for generic PyTorch DDP/FSDP setup without domain parallelism, picking a PhysicsNeMo model or example (use physicsnemo-discover), or non-distributed training questions.

From the source SKILL.md

ShardTensor (physicsnemo.domain_parallel) is a torch.Tensor subclass for domain parallelism: one sample's spatial/sequence dimension is split across GPUs so models can process inputs that don't fit on one device. Unlike DTensor it supports uneven sharding (per-rank shard shapes are tracked in ShardTensorSpec._sharding_shapes).

What this skill does

Physicsnemo Shard Tensor is a community-contributed Claude Code skill in the physics sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/physicsnemo-shard-tensor/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when working with ShardTensor, scatter_tensor, domain parallelism, sequence/spatial sharding, ring attention, DeviceMesh + DDP/FSDP2 hybrid parallelism, or physicsnemo.domain_parallel.

Who uses this skill

The Physicsnemo Shard Tensor Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 183,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the Physicsnemo Shard Tensor Claude Code skill?

Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/physicsnemo-shard-tensor/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.

What does the Physicsnemo Shard Tensor skill do?

Is this skill free to install?

Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.

When should I use the Physicsnemo Shard Tensor skill?

Use Physicsnemo Shard Tensor when your Claude Code task falls under the Science & Research category — specifically in the physics area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Physicsnemo Shard Tensor" or describe the task and let Claude pick).
