Global Tags for Conditions Data

Contents:


---++ <nop>Introduction

This page is intended for the detailed recording of conditions used in the CMS data processing workflows, and description of some key tools.
If you're looking for which global tag should be used to analyse a specific dataset, please refer to the analysis recipe session.

Conditions data for consumption in CMSSW are defined in the Offline Conditions Database, which is read in CMSSW applications via Frontier caching servers.

The set of database tags which together define the offline conditions data are collected together in a Global Tag, which is itself stored in the database. This removes the need for the list of database tags to be defined in separate cffs and therefore decouples the conditions database from the CMSSW release; different Global Tags can be used with a given CMSSW release, with the tag itself specified in the cfg file.

The following file should be included in the cfg for any CMSSW application for which needs to read conditions data:
* from Configuration.AlCa.GlobalTag import GlobalTag

It is then necessary to specify which global tag is to be used, as follows:

<verbatim>
process.GlobalTag.globaltag = 'GlobalTagName'
</verbatim>

For example, for a CMSSW job to process simulated dataset produced in the RunIISpring16DR8 80X campaign, you need to :

<verbatim>
from GlobalTag import GlobalTag
process.GlobalTag.globaltag = '80X_mcRun2_asymptotic_2016_miniAODv2_v1'
</verbatim>

Note that the global tag to be used should always be explicitly specified.

Browsing the Global Tag content

There are 2 main ways to access the content of a Global Tag:
* web interface for browsing and monitoring the changes to a Global Tag is available:
* https://cms-conddb.cern.ch/cmsDbBrowser
* command line tool: the following script can also be run to examine the contents of a global tag
<verbatim>
cmsenv
conddb list TAGNAME
</verbatim>


---+++ How to find out which conditions were used in an existing reconstructed dataset

Tier0 datasets:

You can check the T0Mon page for the runs currently processed at Tier0: T0Mon clicking on the run # will show you the Global-Tag in use.

You can also refer to the table Global Tags for Data Taking in this page.

Other datasets

You can query DBS with:
<verbatim>
dbs search --query='find dataset.tag where dataset=/MyFavorite/Dataset/RECO'
</verbatim>

For Monte Carlo production, and for skims and reprocessed data, the name of the global tag for conditions is included in the DBS dataset name. For example:

/Zmumu/CSA08_CSA08_S156_v1/GEN-SIM-RECO

In this case, the global tag used is CSA08_S156 which can be found in the table above.

Alternatively, you can search for the global tag in the cfg.py file, e.g.:
<verbatim>
process.GlobalTag.globaltag = "80X_mcRun2_asymptotic_2016_miniAODv2_v1"
</verbatim>

Analysis recipes
The recommendation of which global tag (together with other ingredients) should be used to analyze a specific dataset is best found in the analysis recipe page maintained by the PdmV team.


---++ Customization of Global Tags

You may want to use an existing global tag with a modification to one or more of the conditions defined within it. For example, when running muon alignment, it is desirable to use the very latest tracker alignment conditions, which may not yet be in a published global tag, or to use a particular misalignment scenario which is not included in an existing MC global tag.

Note that in the following the connect string is untracked so this is only suitable for tests in which full provenance tracking is not important. See the alternative method using es_prefer below for a fully tracked configuration.

The following example shows a configuration in which the tag Early900GeVCollision_7p4cm_STARTUP_mc, read from the production database, is used for the beamspot, replacing whatever beamspot is specified in the global tag:

<verbatim>
process.GlobalTag.toGet = cms.VPSet(
cms.PSet(record = cms.string("BeamSpotObjectsRcd"),
tag = cms.string("Early900GeVCollision_7p4cm_STARTUP_mc"),
connect = cms.string("frontier://FrontierProd/CMS_CONDITIONS")
)
)
</verbatim>

The following example shows a configuration in which the tags for <nop>TrackerAlignmentRcd and <nop>TrackerAlignmentErrorRcd are taken from an sqlite file, in place of whatever tags are specified for those records in the global tag:

<verbatim>
process.GlobalTag.toGet = cms.VPSet(
cms.PSet(record = cms.string("TrackerAlignmentRcd"),
tag = cms.string("Alignments"),
connect = cms.string("sqlite_file:myAlignments.db")
),
cms.PSet(record = cms.string("TrackerAlignmentErrorRcd"),
tag = cms.string("AlignmentErrors"),
connect = cms.string("sqlite_file:myAlignments.db")
)
)
</verbatim>

The following example shows a configuration for which a 100pb scenario for tracker mis-alignment is read from the production database, in place of whatever tags are specified for those records in the global tag:

<verbatim>
process.GlobalTag.toGet = cms.VPSet(
cms.PSet(record = cms.string("TrackerAlignmentRcd"),
tag = cms.string("Tracker100pbScenario310_mc"),
connect = cms.string("frontier://FrontierProd/CMS_CONDITIONS)
),
cms.PSet(record = cms.string("TrackerAlignmentErrorRcd"),
tag = cms.string("Tracker100pbScenarioErrors310_mc"),
connect = cms.string("frontier://FrontierProd/CMS_CONDITIONS")
)
)
</verbatim>

The set of mis-alignment scenario tags for each release can be found here.


---+++ Alternative method using es_prefer

An alternative method for global tag customization is to use es_prefer: In this case, an es_source is added to the cfg to define the alternative conditions to be used, followed by an es_prefer statement to indicate that this es_source should take precedence over any other source for that condition object (in particular, the global tag). The advantage of this method is that all parameters are tracked, whereas the connect string is untracked in the above approach. The equivalent of the second example above would be:

<verbatim>
from CondDB_cfi import *
process.CondDB.connect = 'sqlite_file:myAlignments.db"'
process.trackerAlignment = cms.ESSource("PoolDBESSource",CondDB,
toGet = cms.VPSet(cms.PSet(record = cms.string("TrackerAlignmentRcd"),
tag = cms.string("Alignments")),
cms.PSet(record = cms.string("TrackerAlignmentErrorRcd"),
tag = cms.string("AlignmentErrors"))
)
)
process.es_prefer_trackerAlignment = cms.ESPrefer("PoolDBESSource","trackerAlignment")
</verbatim>

Special Instructions for using es_prefer with 2XY Releases

More... Close

For 21X and 22X releases there is an es_prefer on the global tag FrontierConditions_GlobalTag_cff.py. For 22X releases it is necessary to use:
<verbatim>process.load("Configuration.StandardSequences.FrontierConditions_CMS.GlobalTag_noesprefer_cff")</verbatim> in your cfg.py in place of: <verbatim>process.load("Configuration.StandardSequences.FrontierConditions_CMS.GlobalTag_cff")</verbatim> For 21X releases, it is necessary to check out Configuration/StandardSequences and edit <nop>FrontierConditions_CMS.GlobalTag_cff to remove the es_prefer.

For both 21X and 22X, depending on the global tag used, you may additionally need to remove lines from <nop>FrontierConditions_CMS.GlobalTag_noesprefer_cff.py (22X) or <nop>FrontierConditions_CMS.GlobalTag_cff.py (21X) to avoid <nop>EventSetup conflicts due to a condition being provided by both the global tag and a fake source. e.g. if you see:

<verbatim>
---- EventSetupConflict BEGIN
two EventSetup Sources want to deliver type="DTMtime" label=""
from record DTMtimeRcd. The two providers are
1) type="DTFakeVDriftESProducer" label=""
2) type="PoolDBESSource" label="CMS.GlobalTag"
Please either
remove one of these Sources
or find a way of configuring one of them so it does not deliver this data
or use an es_prefer statement in the configuration to choose one.
---- EventSetupConflict END
</verbatim>

it means <nop>DT VDrift conditions are included in the global tag you are using, so you need to remove the fake source from the cff by (in this case) removing the line:
<verbatim>from DTFakeVDriftESProducer_cfi import *</verbatim> from <nop>FrontierConditions_CMS.GlobalTag_noesprefer_cff.py (22X) or <nop>FrontierConditions_CMS.GlobalTag_cff.py (21X). If you change a cff.py file, remember to do scram b python.

Finally, make sure you do not have anywhere in your cfg:
<verbatim>process.prefer("CMS.GlobalTag")</verbatim>

*Notes:*
* PHYS14_25_V1 has all the tags stored in the CondDBv2 production account, while the HCAL OOT PU corrections are still in development DB for CondDBv1. Given that 720 is reading the new Conditions, this Global Tag is ok for production. As soon as the tags are migrated to old production accounts, we will anyhow create a new Global Tag.
* The RPC L1T in 2015 will not have any special configuration for 50 ns w.r.t 25 ns, anyway it will be HSCP-oriented: hence, for Run2 simulations, there is no more difference between the two bunch crossing scenarios.
* Unfortunately, there are no existing SIM geometry tags containing only the TECR7 bug-fix for Run2 in 62X, in order to match the one used by the GEN-SIM production (6.2.12.patch1), so we cannot include in this Global Tag -for sake of consistency- the "bug-fixed" SIM geometry (even if not consumed).

Please see section "Summary of Global Tags used in official data re-recos or MC productions" for the latest recommendations.

Mixing prompt and re-reco dataset as recommended here.
The GTs provided here for the analysis are only compatible with 5_3_3_patch1 <= CMSSW < 5_3_8_patch3. The upper release limit is due to Castor saturations compatibility issues.

NOTE1: for all the details concerning how to combine these datasets, please refer to the official PdmV page

NOTE2: the GT suffix "AN4" indicates that the new 2012 b-tag SF have been included in the data GT, with respect to the previous version ("AN3")

NOTE3: the correspondent MC GTs including the new 2012 b-tag SF are also indicated and have to be "paired" with the corresponding datasets Prompt + Reco (here the suffix "PR"), to be consistent with the dataset used to derive them.
