forrtl: error (76): Abort trap signal<br>
<br>
<br>
I am on an HPC facility and after I loaded PETSC module, I have seen that it is configured with INTEGER size = 32<br>
<br>
I solve my problem with these options and it works perfectly with smaller grids:<br>
<br>
-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<br>
<br>
Is it possible to overcome this if I ask them to install a version with INTEGER SIZE = 64?<br>
Alternatively, is it possible to overcome this using intel compiler options?<br>
<br>
Thanks in advance<br>
