I would like to measure core energy, dram energy and also the energy required to transport data from the DRAM to the core. I was wondering if I could use PCM for this. I've been able to obtain DRAM and Socket energy readings. I have also been able to obtain the memory bandwidth used by my porogram. Does PCM support measuring the energy required to transport data? If not, is it possible to use PCM to measure the board power?
In addition, I get the following error (I'm not sure if it's connected to my previous question):
ERROR: QPI LL counter programming seems not to work. Q_P0_PCI_PMON_BOX_CTL=0xffffffff
Please see BIOS options to enable the export of performance monitoring devices (devies 8 and 9: function 2).
