ddtoddl_cfg

This repo contains a simple Python configuration of CMSSW for creating a big XML file of the CMS detector geometry that you can use for SketchUpCMS.

Usage

Check out CMSSW and enter the CMSSW environment

New CMSSW releases for now do not have the patch mentioned below. Regardless, this code will work on newer CMSSW releases (such as CMSSW_12_X) but will not have the fixes the patch addresses (for now).

Also, older releases of CMSSW such as CMSSW_9_X no longer can be run on an lxplus-like environment. So the solution is to run in a Docker container with CMSSW_9_X.

Instructions for both are given below.

In an lxplus-like environment

export SCRAM_ARCH=slc7_amd64_gcc10
scram project CMSSW_12_3_4
cd CMSSW_12_3_4/src
cmsenv

In a Docker container

Create and run the Docker container:

docker run -it --rm gitlab-registry.cern.ch/cms-cloud/cmssw-docker/cmssw_9_2_1-slc7_amd64_gcc530:2020-08-25-a8685cef /bin/bash

This will start the container and you will be in the CMSSW_9_2_1/src dir:

Setting up CMSSW_9_2_1
WARNING: Developer's area is created for non-production architecture slc7_amd64_gcc530. Production architecture for this release is slc6_amd64_gcc530.
CMSSW should now be available.
[12:38:22] cmsusr@695b565ca016 ~/CMSSW_9_2_1/src $ cmsenv

Apply a patch to fix the chimney hole on the magnet

git cms-init
git cms-merge-topic -u SketchUpCMS:fix_chimney_hole_9_0_X

You can read about the disccussion of this patch:

• cms-sw/cmssw#835
• cms-sw/cmssw#836
• cms-sw/cmssw#857

The patch hasn't been merged to CMSSW. But this is necesary for SketchUp.

Compile:

scram b -j 9

Check out this repo

git clone git@github.com:SketchUpCMS/ddtoddl_cfg.git

Note: Unless you also mount your .ssh dir when you start the Docker container you will not have ssh access to the git repo from within the container. In this case you can:

git clone https://github.com/SketchUpCMS/ddtoddl_cfg.git

Create a big XML file

cmsRun ddtoddl_cfg/run_OutputDDToDDL_cfg.py

By default, it uses the geometry config file Configuration.Geometry.GeometryExtended2017_cff and create the big XML file GeometryExtended2017.xml.

The file GeometryExtended2017.xml can be used as an input to SketchUpCMS.

You can specify the geometry config and the output XML filename as arguments to cmsRun. For example

cmsRun ddtoddl_cfg/run_OutputDDToDDL_cfg.py geometryConfig=Configuration.Geometry.GeometryExtended2023D11_cff outFilename=GeometryExtended2023D11.xml

will use one of the Phase 2 upgrade geometry config Configuration.Geometry.GeometryExtended2023D11_cff and create a big XML file with the filename GeometryExtended2023D11.xml.

Create a file for Phase 2 upgrades (including HGCAL)

In CMSSW_13_0_X (tested with CMSSW_13_0_3 on lxplus8.cern.ch) using

git cms-init
git cms-merge-topic -u SketchUpCMS:fix_chimney_hole_13_0_X

after compilation run

cmsRun ddtoddl_cfg/run_OutputDDToDDL_cfg.py geometryConfig=Configuration.Geometry.GeometryExtended2026D88_cff outFilename=GeometryExtended2026D88.xml

where D88 in CMSSW_13_0_3 denotes the Current Phase-2 baseline
