lPowerProbe - A light benchmark tool oriented for energy probing heavely based on likwid
On normal x86 architecture, you can compile the project just using make:
make
It is totally possible to redefine the CC/CXX/LD variables to change the compiler used during the process.
You can install the program and the probes using the install rule. If you need to choose a specific output folder, you can define the PREFIX variable.
lPowerProbe supports MIC. For that, you need to compile using the specialized Makefile:
make -f Makefile.mic
lPowerProbe supports Android (and ARM). For that, you need to compile using the specialized Makefile:
make -f Makefile.android
Your toolchain must be properly configured for crosscompiling to ARM architecture.
./lPowerProbe [OPTION] [prog] [args]
Performs standardized and accurate measurements. It can work in three different modes depending on the prog argument value:
- prog is not specified: daemon mode: the measurement is (re)started/ended when receiving SIGUSR1.
- prog ends by .s: it is compiled and run instrumented as a kernel.
- otherwise: prog is run instrumented as an executable file.
-h, --help Display this help
-v, --version Display the program version
-l, --libraries Probes libraries to load to bench the execution
-r, --repetition=NUMBER Number of repetition for the test
-d, --duplicate=NUMBER Number of process to start
-p, --pinning="pin1;pin2;..." Where to pin the processes
-o, --output="resultFile" Where to write the results
-m, --iteration-mem-size=NUMBER The memory size in bytes used in the kernel per iteration
-i, --iteration=NUMBER The number of kernel iteration
The result is output in a file called 'output.csv' or in terminal if the file can't be write.
The documentation can be generated using doxygen and the following command:
