Comment:
Some more questions:
- I still don't understand why there is an object oriented interface
'''and''' a function interface. Why not only one?
- Wouldn't it be better to gather everything related to parallelism in a
single place? You could mimic what is done for proofs
(`sage.structure.proof.proof`) or global options
(`sage.structure.global_options`). These two are not perfect but at least
they intend to be general and reusable. The object oriented interface
could be something like:
{{{
sage: Parallelism().get('tensor')
1
sage: Parallelism().set('tensor', 3)
sage: Parallelism().set_default(3)
sage: Parallelism().get_default()
3
sage: Parallellism().get_all()
{
'tensor': 3,
'xyz': 2
}
}}}
(though that could be postponed to some other tickets)
- The functions `get_nproc_tensor` and `set_nproc_tensor` should
definitely not be in the global namespace as they are very much
specialized.
