This is the command hwloc-dump-hwdata that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
hwloc-dump-hwdata - Dump topology and locality information from hardware tables
-o <dir> save output files to directory <dir> instead of the default /var/run/hwloc/.
hwloc may benefit from some locality and topology information from SMBIOS or ACPI tables.
They are accessible from raw hardware files under directories such /sys/firmware/dmi/ or
/sys/firmware/acpi/ on Linux. These files are usually only accessible to root.
The hwloc-dump-hwdata tool dumps the useful contents of such files into human-readable and
world-accessible files. The intent is to run the tool once during boot and have the main
(non-privileged) hwloc library gather information from these human-readable files.
hwloc-dump-hwdata is currently only useful on Intel Knights Landing Xeon Phi platforms.
The current list of dumped information is:
Intel Knights Landing memory-side cache characteristics
gathered from specific SMBIOS entries such as /sys/firmware/dmi/entries/14-* and
/sys/firmware/dmi/entries/160-*, and saved in file knl_memoryside_cache.
If the output directory is changed, you may want to set the HWLOC_DUMPED_HWDATA_DIR
environment variable accordingly so that the hwloc library finds the dumped files.
