Write first CUDA kernels that map work onto the grid, coalesce global memory, and keep enough warps resident to hide latency. Use when hand-writing or reviewing a CUDA kernel and it runs far below the bandwidth or FLOPs the card should reach.

From the source SKILL.md

A kernel launches one function across thousands of threads, each working on its own slice of data. The classic first attempt is correct but an order of magnitude too slow: it indexes memory like a serial loop and sizes thread blocks by guesswork. These habits, applied on every kernel, close most of that gap before a profiler is even involved.

What this skill does

Cuda Kernel Basics is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cuda-kernel-basics/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when hand-writing or reviewing a CUDA kernel and it runs far below the bandwidth or FLOPs the card should reach.

Who uses this skill

The Cuda Kernel Basics Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ 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 Cuda Kernel Basics Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/cuda-kernel-basics/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the Cuda Kernel Basics skill do?
Write first CUDA kernels that map work onto the grid, coalesce global memory, and keep enough warps resident to hide latency. Use when hand-writing or reviewing a CUDA kernel and it runs far below the bandwidth or FLOPs the card should reach.
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 Cuda Kernel Basics skill?
Use Cuda Kernel Basics when your Claude Code task falls under the General category — specifically in the general misc 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 Cuda Kernel Basics" or describe the task and let Claude pick). Browse related skills at /category/general/.
What is a Claude Code skill and how does the Cuda Kernel Basics 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. Cuda Kernel Basics is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.
