- The electrical power consumption of the yeti and troll clusters in Grenoble is measured by wattmetre devices from Omegawatt (same as nodes in Lyon or Nancy).
50 measurements per second are recorded for every power supply unit of those clusters' nodes.
Each troll node has a single power supply unit (PSU) and each yeti node has redundant power supply units.
