Hello all, I am porting CESM2.2.2 to a new machine, Sherlock. Using the attached configuration files, I've successfully passed create_newcase, case.setup, and case.build stages, but hit errors at runtime for the test case "b.e20.B1850.f19_g17.test" (compset=B1850, res=f19_g17). It was built...

Hello, I am trying to modify CAM (based off of git tag `cam6_3_139`) to implement an updated gravity wave parameterization in `src/physics/cam/gw_drag.F90`. As part of my work I need to operate on some variables using the global grid rather than the chunked grid that has been scattered to...

Dear all, I have a question about how to use multiple CPUs of a Ubutun server to run CLM5.0. The machine I used to run CLM is a Ubutun server (no batch system) with 40 Intel(R) Xeon(R) Silver 4210 CPUs. One CPU has 10 cores and 20 threads. I wonder how to set MAX_TASKS_PER_NODE and...

Hello everyone, I was recently able to port CESM using an example for the compset QPC4. Currently, I was working on another example for the compset I1850Clm50Sp and I had run the following ./create_newcase --case ~/clm_tutorial_cases/I1850CLM50_004 --res f19_g17 --compset I1850Clm50Sp --machine...

Hello Thanks in advance for your time. I am running cesm2.2.0 and trying to write out a variable to the atm.log file from the gw_drag module. I only wish to know its values for a single vertical column (exact location doesn't matter), and the code that I have written at the end of the module...

Hi all, I'm doing a regional CLM-only run over Africa with anomaly forcing from DATM. To run from 2015-2100 I separate the run into 17-year blocks and set RESUBMIT=4. The model runs fine for the initial set of 17 years and writes history files as expected. However, when the first resubmitted...

Hello, I am trying to add some code for reading some data in cime_comp_mod.F90 referring to the code of cpl reading restart file. But when I add the following line in the code, the program will report a error: I have ensured that the parameters passed into the shr_mpi_bcast are consistent...

Hello everyone, I got an error when I run ./case.setup, and the error info is: ERROR: Could not find a matching MPI for attributes: {'mpilib': 'impi', 'threaded': False, 'compiler': 'intel'} I think this may be caused by a wrong setting of my machine or complier's config file. However, about...

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...

Hello I am trying to run cesm without using case.submit (or .case.run), I mean directly executing cesm.exe, but that does not work at all. My porting is otherwise correct since a "normal" ./case.submit is successful, and I do not understand what is missing. All the needed files seem to be...

Hello there! Recently, I'm running the CESM2.1.1 on Cheyenne with a compset of the piControl. The simulation has successfully run for 55 years, and gets stuck in MPI error during last weekend. Below shows the MPI error in the log file: 1: Opened file...

My environment: When I run the waccmx case, it's been automatically canceled. So I check the log, the key error information show blow: My cesm version is 2.1.3, and you can see the detail in the file named version_info.txt. And you can see the change which I made to the XML files in the bash...

Affected release: CESM2.0.0Affected machine: cheyenne.ucar.eduThere is a known problem with launching MPI jobs on cheyenne such that the user may be required to resubmit the model using the case.submit script repeatedly before the model run is launched successfully. The problem will produce...

This error indicates that the model size requirement is too large to fit the default memory model, solutions vary depending on the case: If you are using netcdf 4.6.0 and newer and pio 1_8_12 or older there is an incompatibility that presents this error.  You may update to pio1_8_14.  If you are...
