Hmm, you are correct :-( > Hong, in petsc-dev, default is interlaced. I ran some tests, I got malloc >> errors when inserting mat values using subcomm of contiguous type. I think >> that PCRedundant with PETSC_SUBCOMM_CONTIGUOUS is buggy. > > PETSC_SUBCOMM_CONTIGUOUS was introduced for multiprocessor bjacobi preconditioner, which has not been used/tested in other situations, likely causes problems. Can you send us a stand-alone code that reproduces the malloc errors?
