Release Schedule

Version Development Freeze Package Freeze Release Notes
3.4.1 / 3.3.26 2017-06-26 2017-07-03 2017-07-11 Independence Day
3.4.2 / 3.3.27 2017-07-24 2017-07-31 2017-08-08

Notes: Additional “urgent” releases may be scheduled for the 4th Tuesday of each month. The Testing date is when acceptance testing will be scheduled for releasable packages; if a package is added after this date, it may not be possible to schedule adequate testing time, thereby forcing it into the next release.

OSG Software Team

  • Dev freeze next Monday
  • Started transitioning hosted CEs to LCMAPS VOMS plugin last week
  • RHEL VMU tests working for the time being even though our RHEL subscription ended. Erin rebuilt RHEL7 exec node, working on building RHEL7 VM image using Aaron's subscription
  • xrootd-cmstfc (contrib) fails to build for EL7, need help with CMake to place libs in /usr/lib64 rather than /usr/lib/

Support Update

  • CTSC (BrianL) - Provided rough size estimate of OSG CE packaging
  • FIT (BrianL) - Assisting transition from GRAM to HTCondor-CE
  • TAMU (BrianL) - SAM tests are still getting held with "Job not found"
  • Syracuse (Derek) - Implemented GPU submission on their HTCondor-CE. Fermilab is creating an entry on the ITB GlideinWMS factories to utilize and test this new GPU capability. OSG will follow suite once singularity configuration is developed.
  • UCSD (Derek) - Gave some assistance to job route configuration for GPUs.
  • Nebraska (Derek) - Assisted in debugging missing hours in WLCG report. Turns out that removed jobs were not being accounted correctly. Also, Multi-CPU jobs and whole node jobs where not being accounted.
