How to setup atlas software

At CERN

• setting up a release

mkdir myRelease
cd myRelease

• write a file called requirements that looks like

set   CMTSITE  CERN
set   SITEROOT /afs/cern.ch
macro ATLAS_DIST_AREA ${SITEROOT}/atlas/software/dist
macro ATLAS_TEST_AREA /afs/cern.ch/user/j/jboyd/release
use AtlasLogin AtlasLogin-* $(ATLAS_DIST_AREA)
apply_tag oneTest
apply_tag 32

• then do:

source /afs/cern.ch/sw/contrib/CMT/v1r20/mgr/setup.csh
cmt config

• the above you only need to do once when you setup the release. the stuff below you need to do everytime you log in, and want to use the release

source setup.csh -tag=12.0.5,runtime 

• this sets up your environment to use this release
• you can check this is done correctly by doing

echo $CMTPATH 
/afs/cern.ch/user/j/jboyd/scratch0/saved_rel5
/afs/cern.ch/atlas/software/builds/AtlasOffline/12.0.5
/afs/cern.ch/atlas/software/builds/AtlasSimulation/2.0.5
/afs/cern.ch/atlas/software/builds/AtlasAnalysis/2.0.5
/afs/cern.ch/atlas/software/builds/AtlasEvent/2.0.5
/afs/cern.ch/atlas/software/builds/AtlasConditions/2.0.5
/afs/cern.ch/atlas/software/builds/AtlasCore/2.0.5
/afs/cern.ch/atlas/offline/external/Gaudi/0.16.1.13-LCG43C-t
/afs/cern.ch/atlas/offline/external/LCGCMT/LCGCMT_43C
/afs/cern.ch/atlas/software/builds/AtlasTrigger/2.0.5
/afs/cern.ch/atlas/software/builds/DetCommon/2.0.5
/afs/cern.ch/atlas/software/builds/AtlasReconstruction/2.0.5

Finding information ad useful links

• HyperNews (need to register first)
• can subscribe to specific lists or browse on web. (PrelimBugs and SWblah particuarly useful for general software issues)

• Search code using LXR

Installing / Running the software at BA (using a kit)

Installing software using the kit

• Need to be root for this
• downloaded latest version of pacman from: http://physics.bu.edu/pacman/

> export http_proxy=http://proxy.uba.ar:8080
> tar -zxf pacman-latest.tar.gz
> cd pacman-*
> source setup.sh
> cd ..

• create directory for your release to go into

> mkdr 12.0.5
> cd 12.0.5

• now download the release (best to use Kit Validation KV although i didnt try that yet)

> pacman -lc am-CERN
> pacman -get am-CERN:12.0.5
<..wait for long time its about 7Gb to be downloaded..>
> ls

Installing EventView cache using a kit

• The EventView software is for Physics analysis from AOD and changes much more quicjy than the release cycle
• To cope with this there is an EventViewGroupArea which contains the latest tags to use the EventView software
• There is a kit (called Event View pacman Cache) for this groupArea which you can checkout
• this is described here
• i did the following and this worked

export http_proxy=http://proxy.uba.ar:8080
[root@blumi root]# cd /home//12.0.6/pacman/pacman-3.20/
[root@blumi pacman-3.20]# source setup.sh
[root@blumi 12.0.6.5]# pacman -get http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/PAT/EventView/:EventView-12.0.6.4

• you find the latest versin to use from here

Running using the kit

• setup requirements file that looks like

set CMTSITE STANDALONE
set SITEROOT /home/12.0.5-HLT-1 
macro ATLAS_DIST_AREA ${SITEROOT} 
apply_tag projectArea
macro SITE_PROJECT_AREA ${SITEROOT}
macro EXTERNAL_PROJECT_AREA ${SITEROOT} 
apply_tag opt
macro ATLAS_TEST_AREA ${HOME}/testing
use AtlasLogin AtlasLogin-* $(ATLAS_DIST_AREA)
apply_tag oneTest 
set CMTCONFIG i686-slc3-gcc323-opt
set DBRELEASE_INSTALLED  3.1.1

• setup like

$ source /path_to_kit/CMT/*/mgr/setup.sh
$ cmt config
$ source setup.sh -tag=12.0.5,runtime
[jboyd@blumi testing]$ echo $CMTPATH
/home/jboyd/testing:
/home/12.0.5-HLT-1/AtlasOffline/12.0.5:
/home/12.0.5-HLT-1/AtlasSimulation/2.0.5:
/home/12.0.5-HLT-1/AtlasAnalysis/2.0.5:
/home/12.0.5-HLT-1/AtlasEvent/2.0.5:
/home/12.0.5-HLT-1/AtlasConditions/2.0.5:
/home/12.0.5-HLT-1/AtlasCore/2.0.5:
/home/12.0.5-HLT-1/Gaudi/0.16.1.13-LCG43C-t:
/home/12.0.5-HLT-1/LCGCMT/LCGCMT_43C:
/home/12.0.5-HLT-1/AtlasTrigger/2.0.5:
/home/12.0.5-HLT-1/DetCommon/2.0.5:
/home/12.0.5-HLT-1/AtlasReconstruction/2.0.5

• to be able to check out packages from cern cvs i use ssh (i found strange problems with kerberos?):

export CVSROOT=:ext:atlas-sw.cern.ch:/atlascvs
export CVS_RSH=ssh

• then checkout ad compile packages in the usual way

$ cmt co -r G4CosmicFilter-00-00-07 Simulation/G4Extensions/G4CosmicFilter
$ cd Simulation/G4Extensions/G4CosmicFilter/cmt
$ cmt config
$ gmake
...

• for Kerberos you would do...

export CVSROOT=:kserver:isscvs.cern.ch:/local/reps/atlas
kinit -4 jboyd@CERN.CH
< passwd >

• check this worked

[jboyd@blumi testing]$ klist
klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_502)
 
 
Kerberos 4 ticket cache: /tmp/tkt502
Principal: jboyd@CERN.CH

04/05/07 16:45:22  04/06/07 02:45:22  rcmd.isscvs@CERN.CH

• but i got the PROBLEM - sometimes checkout doesnt work it looks like:

[jboyd@blumi testing]$  cmt co -r TrigIDSCAN-00-04-66-08 Trigger/TrigAlgorithms/
TrigIDSCAN
cvs [checkout aborted]: kerberos authentication failed: Time is out of bounds (k
