Re: Extracting the Hypre preconditioner type used and PGI compiler su pport for VecGetArrayF90() and VecRestoreArrayF90()

Hi

Can you tell me if there is any way I can extract the name of the Hypre
preconditioner type used i.e. boomeramg, euclid, parasails or pilut? Failing
that is there any chance you could create a routine (with a Fortran
interface) called PCHYPREGetType() that returns the Hypre preconditioner
type used?

I agree that this is an oversight. I will put it in the development version, and it
will appear in the next release.

Also, can you tell me if there is there any likelihood in the near future
for Portland Group Inc (PGI) compiler support to be provided for routines
VecGetArrayF90() and VecRestoreArrayF90()?

This is more problematic. Most F90 compilers have an array descriptor that is a
variant of the NAG format. However PGF90 does not, and these refuse to tell
us the layout. Thus we cannot add those routines.

   Thanks,
