-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).
