Compute technology
""""""""""""""""""
Hardware features the following nodes:
* 168 nodes with
* 1x Intel Xeon Phi 7250 processor (KNL), 68 cores cadenced to 1.4 GHz with SMT 4.
* 96GB memory, 16GBx6 DDR4 DIMMs
* intranode comunications integrated using InfiniBand EDR
* 100% Hot water cooled nodes
* Half of the configuration feature liquid cooled Power Supply Unit (PSU) make this part of the machine 100% liquid cooled.
Each compute node has a theoritical peak performance of 2.765 TFlop/s (double precision) and a power consumption of less than 250W.
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.
