Reposting here as advised from GitHub, apologies. I am working to port CIME to a new machine. I have made a fair bit of progress but am now a bit stuck and had some questions I hope you can help with. In reality the aim is to port CESM 2.x, for which I need to port CIME. My main question is...

Hi, I was wondering if there is some kind of hook where I can include a postprocessing script for CESM2 model runs. Ideally, this script would be called after a st_archive job is completed. I think this could be useful to save storage space: * only save wind speeds at desired levels...

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...

Hi, We are developing our own model based on CLM5.0, and we want to move our work from Cheyenne to Derecho. So I'm wondering how can I define derecho as a new machine in my current cime tool? Thank you! Best,

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...

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...

Hi everyone I'm a new user of CESM and this forum. I'm wondering if someone can help me understand what the most important things to consider are when trying to perform a branch run with different versions of CESM. If this is advised at all... More details: On the machine I'm working on (ARC4...

Hello. I am trying to port cesm2_3_beta08 to implement CAM6-MOM6 coupled model. config_machines.xml, config_batch.xml, and config_compilers.xml that worked in CESM 2.2 version were used for porting cesm2_3_beta08, but the following error occurred during ./case.setup. Previous CESM 2.2 versions...

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/...

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...

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...

I have a case that I have set to resubmit 5 times, writing a restart file at the end of each run: ./xmlchange STOP_OPTION=ndays ./xmlchange STOP_N = 720 ./xmlchange REST_OPTION=ndays ./xmlchange REST_N=720 ./xmlchange RESUBMIT=5 I'm not absolutely sure that this usage is correct, but it does...

Dear CESM community, I'm a beginner with CLM5.0 but I have already spent several months trying to make it work without success. I'm really looking now for some help or advice. In fact, I'm not able to perform a complete run since issues appear at the ./case.submit step. As far as I have...

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...

Hi , I am still trying to port CESM2 to my university HPC. There is no errors wehen I executed ./case.build. After I executing ./case.submit, error pops up (shown below): **************************************************************************************************************************...
