Energy sampling technology
""""""""""""""""""""""""""
Current and voltage sensors based on Hall-effect sensor with a linear sensitivity in range 0-200 A. The sampling occurs at the node level at up to the frequency of 50 kHz and is provided through a HDEEM FPGA on each node.
Power measurements at node level occurs at the sampling rate of 1 kHz at converters and 100 Hz at CPU/DRAM. It is provided through a HDEEM FPGA on each node
`Atos/Bull`_ allow energy access through two frameworks, namely HDEEM VIZualization (HDEEVIZ) and Bull Energy Optimizer (BEO).
HDEEVIZ
-------
Components
- SLURM synchronisation + initialisation
- HDEEM writing results to local storage
- Grafana: Graphical user interface
