Site has been  running well

• Full of Atlas jobs (MCORE, SCORE, Analy and Opportunistic)
• Good efficiency

Illinois down for PM on campus cluster

Updated glibc pushed to all nodes

New Disk at UChicago

• Ceph based
• Migrating LOCALGROUPDISK
• Lincoln is using gfal-copy and srm to copy from dCache to Ceph but slow
• Currently migrated 193TB out of 368TB
• Need Kernel 4.4 to fix controller problems

OSG 3.3.9

• All head nodes have been using 3.3.x stack for a long time without problems
  • CE (HTCondorCE)
  • Squid
  • CVMFS servers/clients
  • GUMS
  • Condor 8.4.3
• Still using 3.2.35 on worker nodes
  • Testing new LSM
  • Used GFAL2 via xrootd, then srm, the fax to try and stagein the file

minRSS and maxRSS now set

• MCORE needs 24GB for reprocessing jobs
• Changed HTCondorCE to request RSS of 24GB (previously 16GB)
• Many nodes are only 2G/core so this can cause idle cores due to lack of free memory
• Might create MWT2_MCORE_HIMEM to handle jobs > 2GB core
  • Redirect to only node with 3GB or more per core
  • MWT2 has almost 4000 cores which fit this criteria
