CESM 2.2.0 cannot run on our HPC

[Yi Yao]

Hello, recently we wanted to run cesm 2.2.0 with the compset I2000Clm50BgcCrop on our HPC breniac, while there are some segmentation faults in the log files and we get no output. Although my colleague has tried several compilation options, reducing the optimization, increasing the stack size, reducing the parallelization, those errors remain. On our breniac, the cesm 2.1.3 can run well despite these errors. The intel compilers used on breniac is "intel/2018a", while on another hpc with "intel/2019a", cesm 2.2.0 can run well. Thus, we also want to know if cesm v2.2 can support the Intel compilers ICC/IFORT v18.0.1?
Thanks in advance!

We have no other reports of problems with these combinations of compilers and compsets. Have you tried building with DEBUG enabled?
./xmlchange DEBUG=TRUE
./case.build --clean-all
./case.build

About a year ago, I received reports of a segmentation fault in CLM initialization (while initializing WaterType) using intel 18. For that user, switching to intel 19 solved the problem. Is that an option for you?

Hey, thanks both! We will update the intel 19 on our HPC, and will update it here.
