HOWTO use the GlueX Singularity Container

Install Singularity

See the instructions on the Singularity site.

Alternately, RedHat Enterprise 7 has an RPM:

yum install singularity

Get the Container

Download gluex_centos7.img, the container.

Get the Software and Support Files

Use one of three methods.

1. Tarball

1. Download the tarball: group.halld.tar.gz. It's 40 GB.
2. cd <directory that will contain "group">
3. tar zxvf <directory containing tarball>/group_halld.tar.gz

2. rsync with direct ssh

rsync -ruvt --delete scosg16.jlab.org:/cvmfs/oasis.opensciencegrid.org/gluex/group/ <directory that contains "group">/group/

3. rsync through ssh tunnel

1. Establish the tunnel

   ssh -t -L9001:localhost:9001 jlab.jlab.org ssh -t -L9001:localhost:22 scosg16
   

2. In a separate shell instance, do the rsync

   rsync -ruvt --delete -e 'ssh -p9001' localhost:/cvmfs/oasis.opensciencegrid.org/gluex/group/ <directory that contains "group">/group/
   

Get a Shell Inside the Container

singularity shell --bind <directory that contains group>/group/halld:/group/halld <directory with container>/gluex_centos7.img
