Perf Torch Sync Free

Category: Security · Sub-category: appsec-tools · Last updated: 2026-05-25

Identify and eliminate host-device synchronizations in PyTorch code. Detects sync points (.item(), .cpu(), boolean indexing, torch.tensor on CUDA), classifies false vs true dependencies, provides sync-free alternatives. Triggers: sync-free, synchronization, .item(), .cpu(), host-device sync, eliminate syncs, CPU stall, non_blocking, set_sync_debug_mode, cudaStreamSynchronize, cudaEventSynchronize, remove syncs, async GPU.

From the source SKILL.md

Sync-free code means the CPU continuously queues work to the GPU without waiting for GPU operations to complete. When host-device synchronizations are eliminated, the GPU works continuously without idle stalls.

What this skill does

Perf Torch Sync Free is a community-contributed Claude Code skill in the appsec-tools sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/perf-torch-sync-free/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Perf Torch Sync Free Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 70,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
