LIKWID#
VERSION=stable
wget http://ftp.fau.de/pub/likwid/likwid-$VERSION.tar.gz
tar -xaf likwid-$VERSION.tar.gz
cd likwid-*
vi config.mk # configure build, e.g. change installation prefix and architecture flags
make
sudo make install # sudo required to install the access daemon with proper permissions
In order to be able to measure the power consumption, you have to load the right modules:
sudo modprobe msr
echo msr | sudo tee -a /etc/modules # pour que ce soit ok au prochain reboot
Hwloc#
In order to visualize the topology of your computer (e.g., number of cores, memories), you may need to install the hwloc package. And then visualize the architecture with the command
sudo apt install hwloc
hwloc-ls & # give it a try
Pour tester#
Config#
cd # retour sur le home directory
mkdir .likwid
cd .likwid
# To be adapted to the installation directory
# ln -s /opt/likwid/usr/local/share/likwid/perfgroups groups #
ln -s /usr/local/share/likwid/perfgroups groups
