I cannot fix this. There is a cycle in the dependencies if I introduce libraryOptions inside package.py so package.py cannot do the consistency check, but it should so it is totally screwed.

Matt could fix it but he'd probably have to fuck up the nice simplicity of the code that is there now :-(!

We were already using a mechanism to get around this circularity. Comments on the aesthetic import welcome.

I think the trauma of seeing the provides interface destroyed part of my brain years ago, hence I didn't realize it could be used here. So, yah, if this works its fine and the way to go. Thanks Barry

It's possible to configure PETSc with the options

--with-64-bit-indices --download-mumps

and compile and run, but it doesn't look like the MUMPS interface supports 64 bit indices. Should the above combination throw an error at configure time?

Yes, there is commented code in the consistency check, I cannot remember why it was commented.

# if self.double and not self.scalartypes.precision.lower() == 'double': # raise RuntimeError('Cannot use '+self.name+' withOUT double precision numbers, it is not coded for this capability') # if not self.complex and self.scalartypes.scalartype.lower() == 'complex': # raise RuntimeError('Cannot use '+self.name+' with complex numbers it is not coded for this capability') # if self.libraryOptions.integerSize == 64 and self.requires32bitint: # raise RuntimeError('Cannot use '+self.name+' with 64 bit integers, it is not coded for this capability')

...

(On a side note, SuperLU_dist and Umfpack are flaky with 64 bit indices, which seems largely related to calling ParMETIS/METIS).

Hmm, never heard such reports. Are you using the --download-parmetis and metis? You should be. Is it reproducible problem? We'd like to fix it.
