Hi,
I try to use the parallel ILU which is provided by hypre library. As from some
discussion from other petsc users, it mentioned that euclid preconditioner from
hypre was removed from petsc. So, I tried the ilu with threshold "pilut", it is
okay as I run in sequential, but it has an error as I tried with parallel :
parilut.c:274: hypre_ComputeCommInfo: Assertion `cinfo->incolind !=
((void *)0)' failed.
I tried with other preconditioner from hypre as boomeramg, and it works fine. I
am wondering that causes this issue with "pilut". I am aware that other petsc
developers mention about some scaling issue with parallel ILU, but I would like
to try it for my problem. Please let me know if you have any idea about this
error. Thanks!
Best,
Khai
