    Setting up a machine using PBS with no queues

    Dear CESM community, I am currently setting up CESM2.2.2 for a new machine (Imperial College HPC). The cluster uses pbs, but the job queue is not specified at submit time. Instead, the queue is chosen based on the job's requirements (and specific queue selection by users appears to be...

    Installing CESM2 on Perlmutter

    Hi all, I'm trying to install CESM2.1.4 on the DOE machine Perlmutter (CPU nodes). I've updated the config_machines.xml and config_batch.xml files. However, I'm unsure how to modify the config_compilers.xml to fit Perlmutter-cpu. After using the revised config_machines.xml, config_batch.xml...

    No problem with hybrid, but a problem with branch

    Hello I would be very grateful to get some help with a branching issue I'm having. I have been managing to successfully "branch" simulations and make modifications via the user namelists, but only when running a hybrid run. I essentially follow the exact same procedure as for a branch (also...

    Weird directory structure with CIME fork

    I made a fork of CIME to add some functionality for a chain submission script I'm working on, but when I point Externals.cfg at it and check out the externals, it completely messes up the cime/ directory structure. I've attached tree output for the normal-sourced and my-fork-sourced cime/...

    Porting CESM2 to a machine with Slurm but no module manager

    Hello, I am currently attempting to port CESM (v2.1.1) to a new machine which uses Slurm for queue management, but which does not use a module system. As such, I am struggling to understand how I can supply information about my environment to CESM when running a case. I am able to set up a...

    PIO errors during porting E3SM/CIME

    Dear E3SM/CIME community, I was trying to port the newest version of E3SM (GitHub - E3SM-Project/E3SM: Energy Exascale Earth System Model source code.) to our cluster (which is not in the support cluster list). I met with a error while compiling the pio (I think) in ./case.build process. Please...

    What can and cannot be changed post-build

    I am used to making changes to user_nl_xxxx after a CIME case has been built, which as far as I know, is fine since namelists are always generated at runtime. Can I also do this with env_*xml variables, via xmlchange? Or does xmlchange need to be used only pre-build? All I am trying to do is...
