Hi Stephen
Graeme's response gives most of the details. (Note that the "E" of SAME
was dropped some time ago so we are talking about wrapping the SAM tests
with each job. I know there are some on this list who think doing this
is madness).
The one thing missing in the response is whether there was input from
sites and I'm a little uncertain where it was first discussed. I do not
remember gathering any feedback. I could not find much in the ops
meeting lists but it apparently came up in the 19th December ROC
manager's meeting via a talk by Piotr:
https://edms.cern.ch/document/808821. As Steve Fisher has pointed out
though, the PPS testing did not reveal any problem which is why it went
into production.
The need to deploy new releases on only a subset of production sites
before widely adopting them is becoming increasingly apparent (as some
of you will know if you've followed Yves's recent ticket
https://gus.fzk.de/pages/ticket_details.php?ticket=21815)
