hpc-strategies

hpc-strategies is a skill for Claude Code, Codex from Katagiri-Hoshino-Lab/VibeCodeHPC. It costs 31 tokens per session (293 once invoked), scanned A, original, MIT.

A folder-naming and layout method for exploring high-performance computing (HPC) optimization ideas across multiple generations. HPC means using powerful computers, often in parallel, to run demanding calculations.

In plain words
What is it for?
Use it to organize folders for CPU, GPU, compiler, and parallelization experiments, and to plan combinations of optimization techniques.
Why use it?
It keeps alternative parallelization techniques visible and easy to combine. A flat layout avoids duplicated work when mixing methods such as OpenMP, MPI, and CUDA.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hpc-strategies scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

HPC Optimization Strategies

Evolutionary Flat-Directory Design

Generations

  1. Seed: Individual techniques (/OpenMP/, /MPI/, /CUDA/)
  2. Crossover: Fuse promising results (/OpenMP_MPI/, /OpenMP_AVX2/)
  3. Breeding: Combine best hybrids (/OpenMP_MPI_AVX2/)

Naming

  • Parallelization strategies: _ separator in implementation order (OpenMP_MPI_AVX2)
  • Metadata: - separator (CUDA-sharedMem)
  • One worker per flat directory

Directory Structure

<hardware>/<compiler>/
├── OpenMP/       # Gen 1
├── MPI/          # Gen 1
├── CUDA/         # Gen 1
├── OpenMP_MPI/   # Gen 2
└── OpenMP_MPI_AVX2/  # Gen 3

Why Flat

Nested hierarchies cause duplicate implementations when combining A+B+C. Flat structure with visibility control (via PG_visible_dir.md) prevents this.

Details: references/evolutionary_flat_dir.md, references/typical_hpc_structure.md

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hpc-strategies is a skill published in the GitHub repository Katagiri-Hoshino-Lab/VibeCodeHPC (39 stars, last pushed 5mo ago), licensed MIT. It adds 31 tokens to every session and 293 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
