Permissions for Additional Input Data on Cori

I recently posted about this issue here, but part of it has not been resolved, so I will be posting it again.

I will include code information, etc., after the issue description.

I am currently attempting to follow the quickstart tutorial to perform a test run on the Cori machine at NERSC. Here are the steps I have performed:

1. Downloaded CESM from the Github repository to a directory called CESM.
2. Created a new case with the following command
./create_newcase --case /global/project/projectdirs/m3698/CESM_simulations/B1850.f19_g17.test --compset B1850 --res f19_g17 --machine cori-knl --project m3698 --walltime 02:00:00 --queue regular
which appears to have worked successfully.
3. In the case directory (/global/project/projectdirs/m3698/CESM_simulations/B1850.f19_g17.test), I invoked the ./case.setup and ./case.build commands. I then modified the runtime settings with the following command
./xmlquery STOP_OPTION=nmonths,STOP_N=12
4. Upon submitting the job to the batch queue using the ./case.submit command, I receive the following error:
OSError: [Errno 13] Permission denied: '/project/projectdirs/ccsm1/inputdata/cesm2_init/b.e20.B1850.f19_g17.release_cesm2_1_0.020/0301-01-01'

The ls -l /project/projectdirs/ccsm1/inputdata/cesm2_init/ command returns

which appears as I would expect. However, the ls -l /project/projectdirs/ccsm1/inputdata/cesm2_init/b.e20.B1850.f19_g17.release_cesm2_1_0.020 returns a permission error

ls: cannot access '/project/projectdirs/ccsm1/inputdata/cesm2_init/b.e20.B1850.f19_g17.release_cesm2_1_0.020/0301-01-01': Permission denied

d????????? ? ? ? ? ? 0301-01-01

I was wondering if it would be possible to use a different set of input data (e.g., b.e20.B1850.f09_g17.pi_control.all.299_merge_v3) which has global read permissions, or to set the global read permissions of the specified input data to open, or some other way to get the input data?

If there is another forum I should post this issue to, please let me know and I will be happy to ask there as well.

Hi Jason,

I change the permission for b.e20.B1850.f19_g17.release_cesm2_1_0.020, can you try it again. It's not the best to try different input data. If you're not sure what you're doing, you could end up with input data that wont work. For example f09_g17 wont work with f19_g17.
