[petsc-dev] [petsc-maint #44001] Re: [petsc-users] Configuring PETSc with Intel compiler.

[Matthew Knepley]

I have been thinking about this. I want to create an entire module that just
crafts responses
to errors. Putting all that knowledge distributed throughout the code is
crazy. Of course, this
entails making an error ontology, etc. which will always break somehow, but
I think its better
than what we have now.

For example, we send this module

  InvalidCompiler, C++, (error, output, status), 'icc'

Its a simple matter to put in a check that recommends using 'icpc' instead.
In fact, we can
even do more tests before giving that error, such as checking that it is the
Intel compiler. I
think this is a much cleaner separation of concerns.

Comments?

What most experimenters take for granted before they begin their experiments
is infinitely more interesting than any results to which their experiments
lead.
