Hi all, I am using SLEPC to solve an eigenvalue problem.
I tried to add -info at run time. And I get instruction: MatLUFactorSymbolic_SeqAIJ(): Run with -pc_factor_fill 3.87526 or use MatLUFactorSymbolic_SeqAIJ(): PCFactorSetFill(pc,3.87526); MatLUFactorSymbolic_SeqAIJ(): for best performance. However, when I tried to add -*st_pc_factor_fill* 3.87526 at run time. It is not recognized at all! WARNING! There are options you set that were not used! WARNING! could be spelling mistake, etc! Option left: name:-st_pc_factor_fill value: 3.87526 Same things happened if I tried *pc_factor_fill* 3.87526 Does anybody know how to change the fill of factorization for SLEPC?
