Systemd Setup for Nightly Benchmarks
This directory contains systemd user service and timer files for running nightly mjlab benchmarks.
Setup
# 1. Create user systemd directory if it doesn't exist
mkdir -p ~/.config/systemd/user
# 2. Copy the service and timer files
cp mjlab-nightly.service ~/.config/systemd/user/
cp mjlab-nightly.timer ~/.config/systemd/user/
# 3. Edit the service file to set your WANDB_API_KEY
# Get your key from: https://wandb.ai/authorize
nano ~/.config/systemd/user/mjlab-nightly.service
# 4. Reload systemd
systemctl --user daemon-reload
# 5. Enable and start the timer
systemctl --user enable mjlab-nightly.timer
systemctl --user start mjlab-nightly.timer
# 6. Enable lingering (so timer runs even when you're not logged in)
sudo loginctl enable-linger $USER
Useful Commands
# Check timer status
systemctl --user status mjlab-nightly.timer
# List all timers and when they'll run next
systemctl --user list-timers
# Run the benchmark manually (without waiting for timer)
systemctl --user start mjlab-nightly.service
# View logs
journalctl --user -u mjlab-nightly.service -f
# View recent logs
journalctl --user -u mjlab-nightly.service --since "1 hour ago"
# Disable the timer
systemctl --user disable mjlab-nightly.timer
Configuration
Edit ~/.config/systemd/user/mjlab-nightly.service to customize:
Environment="CUDA_DEVICE=0"- Which GPU to useEnvironment="WANDB_API_KEY=..."- Your WandB API keyMemoryMax=32G- Memory limit for the training job
Edit ~/.config/systemd/user/mjlab-nightly.timer to change the schedule:
OnCalendar=*-*-* 02:00:00- Default: 2 AM dailyOnCalendar=Mon *-*-* 02:00:00- Example: Mondays only at 2 AMOnCalendar=*-*-* 02,14:00:00- Example: Twice daily at 2 AM and 2 PM
