• Update benchmark functions and improve signal handling in CLI by @weslleyspereira in #6

Full Changelog: v0.9.0...v0.9.1

WattAMeter v0.9.0

What's Changed

• Added MQTT publishing functionality by @xtruan in #3
• Add output directory option for CLI and update related scripts by @weslleyspereira in #4

New Contributors

• @xtruan made their first contribution in #3

Full Changelog: v0.8.0...v0.9.0

WattAMeter v0.8.0

Main changes:

• Move benchmarks to inside the library
• Add documentation to GitHub pages
• New way to add reading frequency. This enables the user to choose its own configuration of tracker through the main CLI
• Remove numpy dependency

Full Changelog: v0.7.4...v0.8.0

WattAMeter v0.7.4

Bug fix. Subprocesses inside a slurm job sometimes can be controlled by slurm, so wait might not work. This version uses kill -0 after wait for more robust graceful exit in wattameter.sh.

Full Changelog: v0.7.3...v0.7.4

WattAMeter v0.7.3

Improve SLURM utilities and examples

• Improve the signal handling
  • Remove USR1 from the killing signals in WattAMeter. Not needed.
  • Python CLI ignores signals during cleanup. Useful because Slurm seems to send multiple TERM signals during timeout
  • wattameter.sh::on_exit sends INT instead of TERM signals to Python CLI. It finishes cleaner with the change
  • Calls scancel with signal INT and only for the SLURM step relative to wattameter. It finishes cleaner with the change
  • Wait after calling scancel. That is necessary otherwise Slurm will send a termination signal to all processes
• wattawait.sh:
  • Use optional arguments with flags.
  • Adds quiet mode
• wattameter.sh:
  • Only parse RUN_ID and SUFFIX. Forward the remaining arguments directly to the Python CLI.
• Create a slurm.sh utils file with the commands start_wattameter and stop_wattameter.
  • It adds variables WATTAMETER_N_STARTED_STEPS and WATTAMETER_SLURM_STEP_IDS to the shell session.
• Update examples and tests accordingly

Full Changelog: v0.7.2...v0.7.3

WattAMeter v0.7.2

wattameter.sh assumes wattameter CLI is in the PATH instead of guessing the Python interpreter. This avoids conflicts with switching between Python virtual environments.

Full Changelog: v0.7.1...v0.7.2

WattAMeter v0.7.1

Adding post-processing functionality to help with analysis.

Full Changelog: v0.7.0...v0.7.1

WattAMeter v0.7.0

• Removes dependency on CodeCarbon

• Adds more data streams to NVMLReader, including utilization rates and NvLink throughput counters

• Adds sleep benchmark notebook to measure sleep time accuracy

• Improve update_time benchmark script with:

  • better time interval estimation
  • use of stress tools for CPU/GPU load generation
  • adds temperature and memory usage to the NVML

Full Changelog: v0.6.2...v0.7.0

WattAMeter v0.6.2

In this new release, the power log files generated by calling wattameter.sh have the simulation ID in the filename. This should improve data handling.
