---+ Global Tags for Conditions Data

<br />%TOC{title="Contents:"}%

---++ &lt;nop&gt;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 [[SWGuideFrontierConditions#Analysis_recipes][analysis recipe session]].

Conditions data for consumption in CMSSW are defined in the [[SWGuideCondDB][Offline Conditions Database]], which is read in CMSSW applications via [[CMS.DatabaseAccess][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:
   * [[https://github.com/cms-sw/cmssw/blob/CMSSW_8_1_X/Configuration/AlCa/python/GlobalTag.py][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 [[SWGuideFrontierConditions#Global_Tags_for_RunIISpring16DR8?redirectedfrom=CMS.SWGuideFrontierConditions][RunIISpring16DR8]] 80X campaign, you need to :

<verbatim>
from Configuration.AlCa.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: [[https://cmsweb.cern.ch/T0Mon/][T0Mon]] clicking on the run # will show you the Global-Tag in use.

You can also refer to the table [[CMS.SWGuideFrontierConditions#Global_Tags_for_Data_Taking][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 [[CMS.GlobalTagContents20X#LinkCSA08S156][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 [[CMS.PdmV#Analysis_Recipe][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 [[#EsPrefer][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 &lt;nop&gt;TrackerAlignmentRcd and &lt;nop&gt;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 [[CMS.SWGuideAlignmentConstants#Constants_for_Monte_Carlo][here]].

<br />#EsPrefer
---+++ 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 CondCore.CondDB.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

<br />%TWISTY{<br />mode="div"<br />showlink="Show..."<br />hidelink="Hide"<br />showimgleft="%ICONURLPATH{toggleopen-small}%"<br />hideimgleft="%ICONURLPATH{toggleclose-small}%"<br />}%

For 21X and 22X releases there is an es_prefer on the global tag [[http://cmssw.cvs.cern.ch/cgi-bin/cmssw.cgi/CMSSW/Configuration/StandardSequences/python/FrontierConditions_GlobalTag_cff.py?hideattic=0&revision=1.15&view=markup][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 &lt;nop&gt;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 &lt;nop&gt;FrontierConditions_CMS.GlobalTag_noesprefer_cff.py (22X) or &lt;nop&gt;FrontierConditions_CMS.GlobalTag_cff.py (21X) to avoid &lt;nop&gt;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 &lt;nop&gt;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 CalibMuon.DTCalibration.DTFakeVDriftESProducer_cfi import *</verbatim>

from &lt;nop&gt;FrontierConditions_CMS.GlobalTag_noesprefer_cff.py (22X) or &lt;nop&gt;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>

---++ Global Tags for Monte Carlo Production

Available global tags for MC production are listed in the tables below. The list of database tags which are included in a given global tag can be viewed by following the links in the tables.

---+++ Mis-calibration and mis-alignment scenarios

Global tags for MC production other than those which use IDEAL conditions apply a smearing of alignment and calibration constants defined through certain mis-calibration and mis-alignment scenarios. Details concerning these scenarios can be found [[CMS.AlCaScenarios][here]]. Additional information about individual tags within the global tags can be found at the links provided [[#TagDetails][here]]

---++ For Run-I and earlier version of Global tags :

* please refer to : https://twiki.cern.ch/twiki/bin/view/CMSPublic/SWGuideFrontierConditions?rev=609*

---++ NOTES:

<br />#NOTENotProd

*[1]* Global Tags labelled with (Not for prod. [[%5B#NOTENotProd][1]]]) are not meant for production since some of the records are read from the preparation account and could not be readable forever.

<br />#NOTESnapValid

*[2]* Global Tags which are *'frozen snapshots'* meant for central re-reco should be used with care since the tags are up to date only until the last run interested by that particular re-reco (which is usually indicated in the documentation). Being frozen, by definition, they can not be further updated and the original version should be used instead. For more details please refer to the [[http://indico.cern.ch/getFile.py/access?contribId=7&sessionId=6&resId=0&materialId=slides&confId=88844][GT tutorial]], looking in particular to slides 6 to 12.
