Hi,
wrt cvmfs: I thought it was agreed that LSST uses: /cvmfs/lsst.opensciencegrid.org Has this changed ?
it hasn't, but LSST is at the beginning and don't have an established infrastructure yet and there are competing repositories. For example ATM the OSG one contains the PhoSim packages the USLSST wants to use for their Data Challenge, while the IN2P3 one contains data management packages the French are working on which also will be needed for the DC so they asked eventually for both. Catalin did a replication work that allows UK sites not to do anything to have the in2p3 repo installed. cheers alessandra On 05/09/2017 15:44, catalin.condurache@stfc.ac.uk wrote:
Hi Daniela,
It might be that the agreement was between LSST users (at some point in the past), however it should not matter which 'lsst' repos are replicated. Anyway in July we tried to enable 'lsst' jobs at RAL and following discussions with few people involved in LSST I started to replicate the lsst.in2p3.fr repo from Lyon. Once this replica was available, the 'lsst' jobs started to succeed at RAL.
So, as I highlighted in my previous message, these inconsistencies should be sorted out internally within LSST, at least in my opinion.
Regards, Catalin

Hi Darren,
Just a question: why you do not stick with the cvmfs repository? There is ‘lsst.in2p3.fr’ repository (maintained at Lyon and replicated by Stratum1 at RAL) where I’d assume all software should be provisioned from.
Is this code you’re talking about only interesting the UK sites? In this case you may want to have another (UK regional) ‘lsst’ CVMFS repository.
Anyway we at RAL have the policy to install a minimal distribution on our WNs (and git is not part of it), assuming the VOs are provisioning their software via CVMFS.

Hi there,
I’m working with LSST folks in Southampton who have code that is updated quite regularly. A while ago, I tested to see whether git could clone at time of execution (I cannot remember which site this was at), and it was a success. However, RAL does not have git installed, as similar code fails at that site. I’ve asked this before and didn’t really get a full answer. Is there any way of knowing which sites have which software installed? It would save new users a lot of pain when trying to get up and running, or even just testing.
Cheers
Darren
