Solid install

Introduction

You will need two things to run set of things for SoLID simulation:

1. SoLID_GEMC, which you will need no matter what,
2. GEMC (vanilla kind) or solgemc (using GEMC as library).

SoLID_GEMC

solid_gemc are collection of SoLID codes for using GEMC

You need it no matter running vanilla GEMC or solgemc

obtain it from SoLID SVN

svn co https://jlabsvn.jlab.org/svnroot/solid/solid_gemc

database_io   dir has geometry/field/banks ready to load into the mysql database
script        dir has scripts to setup env and run the simulation code
analysistool  dir has various packages for analyzing simulation result

GEMC

get it

You have two choices

• Use pre-compiled version on ifarm machines, see howto here https://gemc.jlab.org/gemc/Documentation/Entries/2011/1/2_How_To_Run_GEMC_on_a_JLAB_CUE_Machine.html .It's easy to running batch mode in a terminal or submit a job to farm. for interactive mode, due to the OpenGL 3D rendering, it's too slow to run if you ssh in and do X11 forward to your local machine. The solution is to run vncserver with X window on ifarm and connect to it remote, this way it's not too slow if your network speed is ok. But this's not recommend because it demands a lot resource from ifarm which is shared by many users.

• Use you local copy, you will have full power for the interactive mode and you can choose what version of GEMC to use. Please use 64 bit system, don't use 32 bit system, as it's not future proof and jlab farm has gone to 64 bit Linux system already. follow the instruction here to obtain and compile https://gemc.jlab.org/gemc/Support/Entries/2011/8/1_Step_by_Step.html

note: for local installation, many scripts like "go_clhep", "go_qt4" etc, just use "wget" to download some package from http://www.jlab.org/12gev_phys/packages/sources/, other scripts like "sourcebuild","go_ce", "go_gemc" etc use "svn" to check out from their repository.

note: for local installation, the GEMC installation instruction will obtain you to the latest version of GEMC. To get the production version of SoLID GEMC, see the version control below.

note: to run the pre-compiled production version of SoLID GEMC on ifarm, you need to set env before source jlab.csh like below

setenv GEANT4_VERSION 4.9.5.p01
setenv CLHEP_VERSION 2.1.2.0
setenv ROOT_VERSION 5.32
setenv QT_VERSION 4.8.1
setenv GEMC_VERSION 1.7
source $JLAB_ROOT/ce/jlab.csh

latest SoLID GEMC production version "tag version 1.7, corresponding to trunk revision 8832", updated 2012/11/07

svn address https://clas12svn.jlab.org/repos/clas12/gemc/tags

it depends on other jlab_software packages

general version control info

svn checkout by default always get the latest reversion. If you want a specific reversion, add option "-r revision_number"

how to know your current copy reversion number: go to top svn directory, run "svn update", then run "svnversion"

You'd better use a graphic svn client to get alerted once updates show up. I like "kdesvn" or you may check out this list [1]

here is a WebSVN browser

solgemc

Another way to run solid simulation is to use GEMC as library,

To get the code specific to SoLID, solgemc:

 svn checkout https://jlabsvn.jlab.org/svnroot/solid/solgemc

solgemc Installation Instructions

libsolgem

The library for digitizing GEM output is found in this repository

 svn checkout https://jlabsvn.jlab.org/svnroot/solid/libsolgem/
