Energy measurements

[accio-sunshine]

I am trying to use ramulator-pim to simulate a PIM device similar to the one you used in the NAPEL paper. In this paper, it is mentioned that ramulator simulates the time and energy of the HMC-PIM device.While I can get the execution time, I do not understand what memspec file from DRAMPower should I use. The only 3D-stacked memory in the files is the WIDE I/O memory, but it is not HMC. I also noticed that starting from line 218 of HMC_Controller.h, there is some code to compute the energy using drampower library, but it seems not active. Trying to force this code line and inserting drampower_memspecs = ramulator crashed after a while. Is it accurate to just run cmd-traces using drampower and using the memespec for WIDE I/O memory for HMC ?

To replicate the error : In the file src/HMC_Controller.h, uncommenting these lines starting from 218. . I tried to enable it and insert into the config file for pim: drampower_memspecs = ../common/DRAMPower/memspecs/JEDEC_256Mb_WIDEIO_SDR-266_128bit.xml

/*if (configs["drampower_memspecs"] != "") {
   with_drampower = true;
   drampower = new libDRAMPower(
   Data::MemSpecParser::getMemSpecFromXML(
   configs["drampower_memspecs"]),
   true);
   }*/

Hi, I was able to fix this and obtain DRAMPower stats within ramulator stats itself. But this works only when --split trace= false. When split trace is true for PIM config, ramulator doesn't terminate at all. Here is the log file for split trace =true - Do I need to make any changes?

How did you Obtain DRAMPower Stats? Can you please help with that?
