Essential dependencies:

Migration milestones:

  • Build L1 locally on containers
  • Run single task in S3DF pipeline
  • Update the L1Proc xml template
  • Run full L1Proc in S3DF with LPA

Sustainability and optimization:

  • Get rid of SCons builds for L1 code
  • Upgrade python to v3 and above
  • Can we avoid crumbling altogether?
  • Optimize # of crumbs for new CPUs
  • Use flash for staging instead of xrootd?
  • import the locking script to slurm preempt

Open questions:

  • do we still need a wrapper for cleanup?
  • do we need isocRun for every executable?
  • what are the SLURM queue options?
  • non-preemptable queue: --account fermi:L1
  • how does the scratch space work on S3DF?
  • FSW: need new staging dir, export, logging

Infrastructure needs:

S3DF Cheatsheet:

  • Install ssh config as described here
  • to login from terminal: ssh slacd
  • to ssh as glastraw, run kinit first
  • NOTE: use terminal not XQuartz(?)
  • afs was migrated to: /sdf/group/fermi/a/
  • nfs was migrated to: /sdf/group/fermi/g/
  • Singularity environment: see below

Non-L1  milestones:

  • Test full L1Proc in S3Df with LCI data
  • Update non-L1 xml (flagFT2, merge, setQual)
  • Update L1Proc build/test/update instructions

Additional (non L1) deliverables:

  • Migrate DQM/trending reports
  • Migrate cronjobs for DQM reports
  • Document L1Proc deployment
Where to find/install stuff:
  • working area: /sdf/group/fermi/ground/PipelineConfig/L1Proc
  • pipeline cmd: /sdf/home/g/glast/a/pipeline-II/prod/pipeline
  • singularity example (05/02/23): pipeline task, xml file
  • additional slurm parameters (10/10/23): --account fermi:L1
  • preserve LD_LIBRARY_PATH in singularity (03/12/24): singularity exec --env LD_LIBRARY_PATH=${LD_LIBRARY_PATH}
  • python used by ST: /afs/slac/g/glast/ground/GLAST_EXT/redhat6-x86_64-64bit-gcc44/python/2.7.2-gl4/bin/python
