Hi all, I have two functioning versions of CESM2 ported to the UK HPC ARCHER2 - CESM2.1.3 and CESM2.2.2. As of today, the xmlchange command has stopped working in 2.2.2, though it still works in 2.1.3: e.g. 2.1.3 example ./xmlquery STOP_N Results in group run_begin_stop_restart...

Hi all, I'm porting cesm2_3_alpha17e to my school server (Svante at MIT). It seems to run successfully, but no timing information. No timing output in the ./run/timing/. folder (nothing in checkpoints either), and no timing folder is created in the case directory (attached...

Hi all, I'm working on a port of CESM2.2.2 to the ARCHER2 HPC in the UK. I can build a case but the run fails with /work/n02/n02/jking/cesm/CESM2.2.2/runs/F2000_CESM2.2.2_test00/bld/cesm.exe: error while loading shared libraries: libpiof.so.4: cannot open shared object file: No such file or...

Hi there, I am currently encountering issues while running a case with CESM2.3.alpha17. The problems involve an mpirun error, along with the messages "Submitted job case.run with id None" and "Submitted job case.st_archive with id None". I have attached the cesm.log file, other relevant case...

Hi all, I'm trying to port CESM2.3.alpha17 to my HPC. When I run the ensemble test for F2000climo after installing the model: :/$CESMROOT/tools/statistical_ensemble_test> python ensemble.py --case $CESMROOT/runs/F2000climo_CESM2.3.alpha17.uf.0000 --ect cam --uf --mach archer2 --compset...

Hi all, I'm porting CESM2.3.beta08 to the ARCHER2 HPC here in the UK. My colleagues have previously successfully ported CESM2.1.3 but we have a research need for more recent model features. We have a script to install the model and a module file to go with it (attached). Following the usual...

Hi, I’m trying to install and test CESM2.2 on Derecho. I’ve followed the steps on the UCAR wiki [https://wiki.ucar.edu/display/camchem/Run+CESM+with+Chemistry+on+Derecho] but run into issues on the final step: git checkout release-cesm2.2.01/hist_opt This does not appear to exist, nor...

Hi all, After porting to Derecho, my pacemaker experiments would stop after iterating for some years or months with not very clear error information. Could anyone give me some hints and help? Thank you in advance! [1] Case Status log: 2023-10-15 10:39:33: case.run error ERROR: RUN FAIL...

Hi all, I'm wondering if there is a version of CESM2 on git that is out-of-the-box compatible with Derecho? If not, does anyone have advice on how to edit the config_machine.xml file so that the model can run on Derecho?

Hi all, I'm working on Cheyenne and currently can't submit anything into the batch queue. When I run qcmd -- ./case.build to compile a model run (CESM2.2.0), I get: Connection refused qsub: cannot connect to server chadmin2.ib0.cheyenne.ucar.edu (errno=111) Error: PBS could not successfully...
