If you have an homogeneous cluster, architecture-wise, you can hardcode the 
architecture in your module file. But I guess that if you ask, that's not the 
case. 

I would try to determine the machine type in the module file itself. Not sure 
if a modulefile could get the result of an external $(uname -m | sed 
's/x86_64/intel64/;s/i[3-6]86/ia32/'), but the modulefile(4) manpage mentions 
a uname directive.


For me, Intel xxxvars.{c,}sh files never really fit into the module model. But 
I guess that's not what they have been designed for. So I used to give a look 
at was they do, which is often not much, and try to re-implement them using a 
modulefile. It would give something along the lines of:
