v4.2.3
bdef860

This release add new recipes in directories:

  • toss3.cython
  • toss3.numpy
  • v42.toss3.unstable

to enable LDMS v4 and sos v4 for TOSS 3. While substantial testing has been conducted in testbed machines and full-scale Cray installations, production TOSS testing has not been completed. Thus the build recipe is tagged as 'unstable'.

New in this release:

  • packaging changes

    • sosdb is now packaged separately from ldms, but the build recipe for sos is started with firerpms.sos next to the ovis firerpms script.
      • sosdb depends on new cython and numpy packags for toss in toss3.cython and toss3.numpy recipe directories.
      • The cython and numpy packages install to /opt/$package independently and have been created because there is no batteries-included python such as anaconda in the base TOSS Linux.
      • The new python packages do not conflict with the similar but older system-provided packages, and 'module' files are provided.
    • The firerpms script for v42.toss3.unstable can be used as-is (sos store for ldms included) or sos can be entirely excluded by manually changing the 'sospkg' definition at the top of firerpms.

  • version 4.2 ldms changes

    • Compared to version 3, C APIs, command line arguments, python APIs, and wire protocols have all changed. Most of the details will not be given here.
    • Fortunately, all of this is hidden by the systemd startup script wrappers from most ldmsd administrators.
    • Help with configuration can be obtained via posting issues to https://github.com/ovis-hpc/ovis/issues or (less preferred) the usual email channels.
    • Munge authentication is now available as an alternative to shared secret files. Administrators must now set LDMS_AUTH_TYPE in ldmsd.local.conf; type 'ovis' provides the v3 authentication behavior.
    • Administrators can now use the genders configuration file to suppress or select individual metrics in a metric set being stored. See 'man ldms-attributes' section 'STORAGE PLUGIN CUSTOMIZATION' for details.
    • DRY configuration for multilevel aggregation: Administrators can now configure an aggregator with its own genders file and refer to producer genders files. This enables correct automatic construction of storage policies rather than making customary assumptions.
    • Administrators can run their own additional logic (see man ldmsd-genders) via LDMSD_DEBUG_CONFIG_FILE (appended to generated daemon configuration script) and LDMSD_START_HOOKS (programs to run before ldmsd starts). The latter defaults to populating 'fake' slurm job info data on nodes that are not slurm managed.
