Triton modules & environments

Prefer modules over ad-hoc installs. Live docs: modules, Python, PyTorch, conda/mamba. Module versions drift — module spider / Docs MCP over memory.

Operating rules (read first)

1. Safety tiers

   • Read-only — module spider / avail / list / show on request.
   • Create — propose module load lines and environment.yml; create or update conda/mamba envs only with user approval; show the plan first.
   • Avoid-zone — silent pip/conda/mamba into shared or global paths, bulk env rebuilds, wiping conda config. Write a reviewable command list; run only after confirmation.

2. Anti-priors

   • Own envs: module load mamba then source activate ENV — not conda activate.
   • Put module load … inside the sbatch script / interactive session.
   • Keep conda caches/envs off tiny $HOME (mamba first-time setup → $WRKDIR).
   • Prefer central scicomp-*-env when it covers the need.

3. No heavy CUDA builds/tests on the login node — use Slurm (sinteractive / short sbatch). Agents: code.triton.aalto.fi.

Quick start: common requests

• "What module for X?" module spider PATTERN before inventing names. Common loads: references/concepts.md.
• "Python / PyTorch on GPU." Older GPUs (V100-era): scicomp-python-env. Newer GPUs (e.g. B300): scicomp-pytorch-env/2026.1 + GRES min-cuda-cc:80 — confirm versions with spider / PyTorch app page.
• "Use / create my conda env." Activation lines and first-time setup: references/code-patterns.md. Do not recreate silently.
• "Package not found." Spider → central env → documented app page → only then a user env with approval.

Reference material

• references/concepts.md — Lmod workflow, common loads, anti-patterns.
• references/code-patterns.md — activate lines, mamba first-time, env create.
