[lukasz@blueslogin4 ~]$ srun --pty -p acme-small -t 01:00:00 /bin/bash
[lukasz@b566]$ singularity shell --hostname singularity e3sm.sif

(after here you are inside the container)
Singularity> cd E3SM/cime/scripts/
Singularity> ./create_newcase --case singularity.A_WCYCL1850.ne4_oQU240.baseline --compset A_WCYCL1850 --res ne4_oQU240 --mach singularity
Singularity> cd singularity.A_WCYCL1850.ne4_oQU240.baseline/
Singularity> ./case.setup
Singularity> ./case.build
Singularity> ./case.submit

There is no batch system so ./case.submit launches an interactive job and you get to watch the output from mpirun and will have to wait until the model finishes. So instead launch it like this:

Singularity> ./case.submit >& case.out &

You can then cd to the rundir and look at the log files as they are made.
