>> to CHEP’09 – “ready but there will be problems”
Whilst there is no doubt that the service has “stepped up” considerably since e.g. one year ago, can
We (providers) live with this level of service and the operations load that it generates?
The experiments live with this level of service and the problems that it causes? (Loss of useful work, significant additional work, …)
Where are wrt “the challenge” of CHEP 2004?
Over the past few years there were a number of technical problems related to the LHC machine itself
For me, a particularly large slice of “humble pie” came with the “IT problem”
This was not about Indico being down or slow, or Twiki being inaccessible, it was about the (LHC) Inner Triplets
To many, the collaboration is perceived to be “LHC machine + detectors” – “computing” is either an afterthought or more likely not a thought at all!
