A repository of scripts that can be used to monitor energy consumption for any program.
- Linux: Right now jouleit uses the Intel "Running Average Power Limit" (RAPL) technology that estimates power consumption of the CPU, ram and integrated GPU. This technology is available on Intel CPU since the Sandy Bridge generation(2010).
sudo ./jouleit.sh cmd
jouleit offers a set of options to help benchmarking and testing programs. The avialable options are
| Flag | Description | Default value |
|---|---|---|
| -g | print the details of all sockets instead of the aggregation | False |
| -b | print the results in the format of *KEY1:VALUE1;KEY2:VALUE2.. | False |
| -l | list all the available domains (CPU, DRAM, etc.) and print them in the form of a header of CSV | |
| -c | print only the values in CSV format (value1;value2;value3). We recommend using this after running jouleit with the -l flag to see the order of the measured values | false |
| -s s0,s1,.. | measure only the energy of the component in the sockets s1,s2... | all the available sockets |
| -o filename | redirect the output and the log of the executed program to the file filename |
current terminal |
| -n N | run the program N times and record the measured values in data1234.csv file |
|
| -h | display the help message |
we want to measure a Python script called work.py
instead of running it like this
python work.py
we run it with jouleit like this
sudo ./jouleit.sh python work.py
if we want to aggregate the results we can use the flag -g
sudo ./jouleit.sh -g python work.py
