Solgemc Installation Instructions

This page needs the following updates:

• ifarml6 is not a valid hostname anymore, this should reflect the situation for the main ifarm node
• solgemc_env.csh and all linked environment variables are only valid for older RHEL 5.3 systems, not the current CentOS 6.2 systems

Quick and Dirty Setup

Run the following on ifarml6 to get set up:

    svn checkout https://jlabsvn.jlab.org/svnroot/solid/solgemc
    source /w/halla/parity/solid/solgemc/solgemc_env.csh
    cd solgemc
    scons

Add the following to your .login on the CUE machines

    if ( `uname -i` == "x86_64" ) then
         source /w/halla/parity/solid/solgemc/solgemc_env.csh
    endif

More info

solgemc uses GEMC built as a shared object. A version of GEMC has been built this way and can be found on the Hall A work disks (built for 64-bit on ifarml6)

/w/halla/parity/solid/gemc/production

To build and use solgemc, you need to be able to build GEMC in general. All the software is available on ifarml6 in the following locations:

• Geant4

/work/halla/parity/disk1/geant4/geant4.9.4

• EVIO

/w/halla/parity/solid/gemc/evio

• Qt4

/site/Qt/4.6.2/Linux_CentOS5.3-x86_64-gcc4.1.2/

• SConstruct Scripts

/w/halla/parity/solid/gemc/scons_scripts

   setenv GEMC /w/halla/parity/solid/gemc/production
   setenv EVIO /w/halla/parity/solid/gemc/evio
