CPU

  • RAL

  • Northgrid

    • Low CPU efficiency still seen for SHEF; configured to reasonable (expected) baseline setting, and iterate from there.
      • MC generation is good; appears to be network / file transfer that limits the efficiency

  • London

    • OX moving of WNs went ok

  • SouthGrid

  • Scotgrid

    • cvmfs issues; rpm updates may have corrupted cache, and segfault autofs
      • (newer 5 series of) Kernel bug being discussed in cvmfs mailing lists (but may? be backported to old kernels?)
