Hi Darren, We have a page (http://pprc.qmul.ac.uk/~lloyd/gridpp/votable.html) that shows which sites support which VOs that might be useful to new people.

Hi Catalin,
Even before this project got underway, we were warned to not do that for code that is in such active development. The time it takes for CVMFS updates to filter down can take far too much time for testing. I spent the last few days in Southampton last week and we were pushing changes to GitHub several times an hour that could instantly be available for testing. That’s simply not possible from what I understand/was told about CVMFS.
Also, the Lyon repo is not available at all sites for LSST folks, as I found out the hard way. The specified repo I was told after many days of failure is apparently /cvmfs/lsst.opensciencegrid.org, which we successfully use to set up EUPS, which we then, in turn, use to set up the many packages needed for this specific code (which are also not available on either the LYON or opensciencegrid repos and so packaged into a tarball on an SE). This is another issue for new folks trying to work on GridPP. There’s no real clarity of what CVMFS repos are available, what sites you can run at, what tools they include both at the site or on the repos, etc.
Cheers

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
