[Modules] Environment Modules for Multi-arch Environment

[Michael K. <mi...@do...>]

Folks,

I have the following setup:

/net/software/{x86_64,aarch64,armv7l,riscv} contains all software on 
shared storage.  /net/software/modules/modulefiles contains the 
corresponding module files for these software packages, e.g., 
clang/13.0.0, gcc/9.2.0, etc.  The module files use the $ARCH 
environment variable to setup the environment for the software.

Since I do not have all software packages compiled for all systems, I 
was wondering what would be the best way to avoid loading (or even 
better hide) modules that do not have the software package for a 
particular architecture?

I have come up with either checking in the module file, if the software 
exists and if not throw some sort of error.  I could also have 
$ARCH-specific module locations and use "module use" on these locations, 
depending on the machine I'm on.  But is there a better way to automate 
all this w/o too much duplication of module files or code in the module 
files?

I'm using Modules Release 4.4.1 (2020-01-03), all systems are Ubuntu 
systems.

Kind regards,
