MPICC command not found when building

[freddyzhangy]

Hello,

I tried building a case for CESM 2.0 using an MPI, but I get an error stating that the mpicc command is not found. However, I loaded in the module on my machine and have successfully run other programs that require MPI. I have attached the error that shows up when I try to build a case.
Do you guys have any ideas on how to solve this problem?

Thanks

Hi Freddy,

CESM 2.0 builds in it's own environment. If you loaded a module from the command line, it's not being used. You'll need to add the load into env_machine_specific.xml.

Hi Chris,

Thank you so much for your response. I now understand why the mpicc command is not working. However, I am not sure where to add the load in env_machine_specific.xml. Could you help me with that? I have attached the content in the env_mach_specific.xml file onto this post.

Thanks,
Freddy

Hi Freddy,

If you're using gnu, then you'll add your module load in this section of the file.

<modules compiler="gnu">
<command name="load">compiler/gnu/8.2.0</command>
<command name="load">mpi/3.3/gcc-8.2.0</command>
<command name="load">your_module</command>
<command name="load">tool/netcdf/4.6.1/gcc-8.1.0</command>
</modules>

But looking at this, I would assume that the mpi/3.3/gcc-8.2.0 module would have the mpicc path in it. But I don't know how
your machine is setup.

Hi Chris,

I just added the line into the xml file and it works now!
Thank you so much for your help.

I have the exact same error message as Freddy's mpicc command not found during build. However a search of all files in my cesm download (I have v2.1.3) with the wildcard "env_mach_specific*" returns three files ending in .xsd, .py, and .pyc; not the file ending in .xml. Am I missing this file? Where should I look?

I too am attempting to compile with gnu and have similar <command name="load">compiler/gnu/8.2.0</command> etc. lines present in 'config_machines.xml' under ../my_cesm_sandbox/cime/config/cesm/machines/ to load in openmpi and netcdf. Do I need these present in a 'env_mach_specific.xml' file somewhere too?

I resolved this issue myself. Updated path to openmpi in config_machines.xml fixed it.

I'm sorry to bother you, but I want to know that in line "<command name="load">your_module</command>", what exactly do we need to add in "your_module"?
