💖 LIKWID-GENTOPOCFG 💖

okay bestie, welcome to likwid-genTopoCfg — the general commands manual page, but make it ✨slay✨

🌸 NAME 🌸

likwid-genTopoCfg — grab your system's topology and write it to a file so LIKWID starts up wayyyyy faster 🏃♀️💨

🦋 SYNOPSIS 🦋

likwid-genTopoCfg [-hv] [-o <filename>]

✨ DESCRIPTION ✨

so like, likwid-genTopoCfg is a command line application that stores the system's CPU and NUMA topology to a file. LIKWID applications then use that file to read in the topology fast instead of re-gathering all the values every single time. it's giving efficiency, no cap 🫶

💅 OPTIONS 💅

  • -h, --help — prints a help message to standard output, then exits. the ✨little helper✨ moment.
  • -v, --version — prints a version message to standard output, then exits. say hi to the version, then dip 👋
  • -o, --output <filename> — sets output file path. default is /etc/likwid-topo.cfg — yeah, it's THAT file 🎀
