name	voltage-park
description	Provision and manage Voltage Park H100 GPU instances. Use when the user needs to spin up H100s, SSH into VP instances, transfer files, or terminate cloud GPU instances.

Voltage Park H100 Management

Permissions

• NEVER provision without explicit permission
• ASK before spinning up H100s when blocked on GPU tasks
• Do NOT auto-terminate - user may run multi-hour experiments

SSH

ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i ~/.ssh/id_ed25519 -p <PORT> user@<IP>

Setup (fresh instance)

source /opt/anaconda3/etc/profile.d/conda.sh && conda activate base
curl -LsSf https://astral.sh/uv/install.sh | sh && source $HOME/.local/bin/env

Available: nvcc, conda, PyTorch 2.5.1, git. Missing: cmake, pip3, uv.

File Transfer

scp -P <PORT> -i ~/.ssh/id_ed25519 <LOCAL> user@<IP>:<REMOTE>
rsync -avz --progress -e "ssh -i ~/.ssh/id_ed25519 -p <PORT>" <SRC> <DST>

Data Persistence

WARNING: Instances are EPHEMERAL - download results before terminating. Stopping preserves data but costs storage.
