HOWTO use the GlueX Singularity Container
From GlueXWiki
Contents
Install Singularity
See the instructions on the Singularity site.
Alternately, RedHat Enterprise 7 has an RPM:
yum install singularity
Or on Ubuntu 16.04 and earlier:
go here and follow the instructions
Or Ubuntu 16.10 and later:
sudo apt-get install singularity-container
Get the Container
Download gluex_centos-7.7.1908_sng3.8_gxi2.20.sif, the container.
Get the Software and Support Files
Use one of three methods.
1. tarball
This method is not supported at present (December 13, 2018). If you would like to see it revived, contact the Software Working group.
- Download the tarball: group.halld.tar.gz. It's 18 GB.
- cd <directory that will contain "group">
- tar zxvf <directory containing tarball>/group_halld.tar.gz
2. rsync with direct ssh
rsync -ruvt --delete --links scosg16.jlab.org:/cvmfs/oasis.opensciencegrid.org/gluex/group/ <directory that contains "group">/group/
3. rsync through ssh tunnel
- Establish the tunnel
ssh -t -L9001:localhost:9001 login.jlab.org ssh -t -L9001:localhost:22 scosg16
- In a separate shell instance, do the rsync
rsync -ruvt --delete --links -e 'ssh -p9001' localhost:/cvmfs/oasis.opensciencegrid.org/gluex/group/ <directory that contains "group">/group/
4. Run CVMFS
There are two options here:
Depending on choices made during installation the directory that contains "group" will be something like
/path/to/cvmfs/oasis.opensciencegrid.org/gluex
Get a Shell Inside the Container
singularity shell --bind <directory that contains "group">/group/halld:/group/halld <directory with container>/gluex_centos-7.7.1908_sng3.6_gin2.15.sif
Set-up the Developer Toolset package (optional)
The standard GCC version is 4.8.5. Perform the following step if you would like to use the GCC 8.3.1 compiler.
scl enable devtoolset-8 bash
or
scl enable devtoolset-8 tcsh
Set-Up the GlueX Environment
For bash:
source /group/halld/Software/build_scripts/gluex_env_jlab.sh
or for tcsh:
source /group/halld/Software/build_scripts/gluex_env_jlab.csh
