Hi,

I would recommend we refrain from installing GSL. When it will be widely needed it will come with AnalysisBase. If needed for some special test by you Giordon, we could add it to our Tier3 only.

And I would not really worry about AnalysisBase 2.0.16 as it was crashing on every single read test done by Johannes E.  

Cheers,

Ilija

I just heard from Ulla on one point of this:

"Hi Giordon,

As you probably have realized this is not by Design but a nasty consequence of the  way the new root versions are setup.

Hence we don't know this at the time we announce the release  (I routinely test the release on non-linux mashines but as it appears this cluster is well-equipped).

I am working on a known-issues list on  the  AnalysisBase wiki.  Many thanks for the reminder to include this item. I will include some advise there. When we announce 2.0.17 we will include this advise.

This is a good question, and from what I'm seeing -- they're developing it to work "as-is" on lxplus. As far as I can tell, lxplus provides GSL locally. Why they're not shipping it with ALRB, or at the very least, within rcSetup, I don't know. They've frozen 2.0.16 and are working on new release versions so if they were going to ship it, I would've expected ALRB to have updated to reflect that change.

Hi Giordon and Lincoln,

Is installing this locally the recommended action? Is it not going to be provided by ALRB? I am a little bit hesitant to have it installed locally, because then we need to keep on top of keeping it up to date and in theory we might be using a different version that produces different results to someone else. Surely the AnalysisBase tag is tied to a specific version of GSL (in exactly the same way as it is meant to be used with a specific version of a centrally-compiled/managed ROOT) to ensure consistently between everyone in ATLAS.

For example we have seen this problem with the two versions of emi: the local one on the T3 no longer works because it wasn't updated with the new CERN VOMS servers, but the ALRB cvmfs one does work because it is maintained centrally by people whose job it is to keep this stuff working.

Thanks,

Miles

Hi Giordon,

Thanks for the heads up. I've forwarded this to the atlas-connect-l list and gsl should be rolling out on all of the MWT2, UCT3, and UC3 workers over the next few hours.

Thanks,

Lincoln

Hi all,

As of Analysis Base 2.0.16, we will need to have the GSL installed on computers that would like to run xAOD using RootCore. Release details (https://twiki.cern.ch/twiki/bin/view/AtlasProtected/AnalysisBase) but does not mentioned needing GSL.

In the meantime, the next stable base will be 2.0.13 (without GSL dependencies).

Thanks,

Giordon (see output below)
