 Note: all measurements were made "at the wall" using a Kill-O-Watt meter.
 
-=== Idle Power ===
-While idling, the head node draws about 75 Watts and each of the three compute nodes draw 62 Watts for a total of 261 Watts. Of course, if the nodes are not being used, they are manually powered down to stand-by mode (5Watts) and then restarted with WOL (wake on lan). I would like to integrate this into the scheduler.
+=== Idle and Load Power ===
+The following table sumerizes the loads (in Watts) measured for each commponent.
+ 
+||  ||Idle||Load|| Components||
+||Head Node E6550|| 78 || 128 ||2GB RAM, 250 GB HDD, 2 extra NICs, GeForce 6200 256MB PCI graphics card||
+||Head Node Q6600||92  ||148  ||2GB RAM, 250 GB HDD, 2 extra NICs, GeForce 6200 256MB PCI graphics card||
+||Worker Node E6550|| 57 ||96 ||2GB RAM, 1 Extra NIC||
+||Worker Node Q6600|| || 125 ||2GB RAM, 1 Extra NIC||

 === Compute Load ===
-When it is fully loaded running the HPL benchmark Norbert draws between 371-483 Watts. The number varied as the benchmark progressed which I assumed is an indication of how modern processors are managing power consumption based on load. Even with the maximum power draw, the power performance ratio is a comfortable 10-11 Watts per GFLOPS.
