Getting better multicore performance requires changing the algorithms to
better reuse L1 cache. This means moving away from assembled matrices
where possible and of course finding good preconditioners.
I do not know how to move away from assembled matrix. As I have to
reset values to the
works fine for me.
Perhaps you can retry after 'rm -rf externalpackages'
If the problem persists - send configure.log to petsc-maint at mcs.anl.gov

Hello
I try to configure petsc (p9) with SuperLU and I get error message
Sorry, we don't have the Fortran interfaces for these operations.
You can use
call PetscOptionsSet(-
ksp_gmres_classicalgramschmidt,PETSC_NULL_CHARACTER,ierr)
call PetscOptionsSet(-
ksp_gmres_cgs_refinement_type,REFINE_IFNEEDED,ierr)
before creating the KSP object.

Thanks, for help. Strange enough It is working now.

Looks like you have a corrupt tar.gz file; recommend deleting it and getting
it again.
