Calling hypre

[Ben Tay]

Hi,

presently I am using ./a.out -pc_type hypre -pc_hypre_type boomeramg to use
hypre.

However, I have 2 matrix to solve and now I only want one of them to use
hypre, while the other use jacobi + bcgs.

for the solver using hypre,

initially it's just:

call PCSetType(pc,PCLU,ierr) - direct solver

I now changed to

call PCSetType(pc,hypre,ierr)

call PCHYPRESetType(pc,boomeramg,ierr)

However, I got the error msg:

fortcom: Error: petsc_sub.F, line 125: This name does not have a type, and
must have an explicit type.   [HYPRE]
        call PCSetType(pc,hypre,ierr)

Sorry I don't really understand the eg. hyppilut.c since my knowledge of the
c language is very basic.

So how should I set the options to use hypre?

Thank you.
