[petsc-users] How to specify superlu_dist tolerance in Petsc

[Barry Smith]

  What do you mean by tolerance? SuperLU_DIST is a direct solver and as such doesn't have the concept of convergence criteria. If there is a SuperLU_DIST parameter you wish to set let us know the name of the parameter and we'll try to add support for setting it.
