Agenda:

• SNL can now only host on SKYPE (cannot host or participate on Zoom). Contact ANN or respond to the pinned issue about telecons if you need info.
• Investigating how to run a virtual LDMSCON2020 (stay tuned)
• Waiting on scale testing to tag version 4.3.4
• Scale testing on a variety of platforms going on
  • Cray XC40 with CLE6
  • Cray XC40 with CLE7
  • TOSS 3 (RHEL7)
• Changes
  • loadavg sampler added to V3.4.14 & v4.3.4
  • syspapi
    • Previously this sampler required the PAPI library version with which it was compiled. It has been modified to attempt to use whatever PAPI version is installed.
  • Kokkos Profiler enhancements
    • The schema in which Kokkos data is stored has been modified to match the v4 schema used with other samplers
  • SOS
    • The Hash Table index has been modified to support LUB and GLB, previously it did not because hash tables are not ordered.
    • More informative error messages
  • OVIS
    • Kokkos store modifications to match profiler changes
    • Removed stream data reply message that could cause spurious errors in the log
    • Cray System Sampler modifications to include Lustre data
    • Various build improvements for different platforms
    • A new sampler called loadavg
    • Fix buffer overflow bug in ldms_ls that would occasionally cause it to crash
    • A fix to the configuration logic that would leak file descriptors
