likwid-getTopoCfg: A config file writer to store system topology

Introduction

likwid-genTopoCfg is a command line application that stores the system's CPU, Cache and NUMA topology to a file. LIKWID applications use this file to read in the topology fast instead of re-gathering all values. The path to the topology file can be set in the global configuration file likwid.cfg. Furthermore, some default paths are checked:

• /etc/likwid_topo.cfg
• <BUILD_PREFIX>/etc/likwid_topo.cfg

Options

-h, --help		 Help message
-v, --version		 Version information
-o, --output <file>	 Use <file> instead of default
