RAL Tier1 weekly operations castor 29/04/2016
AD discussion>>>>
batch farm > 10k job slots on farm (15 > 26k)
most throughput from fts
batch farm & fts about equal number of files
CMS throttled - 1200 job slots (direct IO) - 1200 as it works, MoU should be 3k
Atlas - fair share 7-8k jobs ... pos prev max load + 20%?
LHCb - ok at the moment
Alice use farm (quite significant) but dont really use castor
Non LHC vos - mostly going to tape as 'archive' >>> will probably go to echo
2 defn of efficency success/total or cpu time/wall time - CMS raising issues with both
AP - come up with all potential solutions even if ££££
- 2014 disk serevrs can be put into castor - poss cms .. for IO throughput
reduce the number of drives used (castor partitions) on above machines
atlas log files could be put onto echo
find prob workflows
get echo working
second raid in hardware
