[petsc-users] Error on INTEGER SIZE using DMDACreate3d

[Pierpaolo Minelli]

Hi,

I am trying to solve a Poisson equation on this grid:

Nx = 2501
Ny = 3401
Nz = 1601

I received this error:

[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------

I am on an HPC facility and after I loaded PETSC module, I have seen that it is configured with INTEGER size = 32

I solve my problem with these options and it works perfectly with smaller grids:

-dm_mat_type hypre -pc_type hypre -pc_hypre_type boomeramg -pc_hypre_boomeramg_relax_type_all SOR/Jacobi -pc_hypre_boomeramg_coarsen_type PMIS -pc_hypre_boomeramg_interp_type FF1 -ksp_type richardson

Is it possible to overcome this if I ask them to install a version with INTEGER SIZE = 64?
Alternatively, is it possible to overcome this using intel compiler options?

Thanks in advance
