most efficient way to use local CSR matrix?

Mark, Barry, Thanks for the help. For now I'm sticking with the approach of copying the csr matrix and using the csr data structures to do the preallocations. I'll eventually get around to writing the code for assembling directly into the petsc matrix. I have two more questions. 1) On 1

missing CHKERRQ in MatNullSpaceRemove()

While trying to update petsc4py to latest changes in petsc-dev repo, I've noticed that at the very end of MatNullSpaceRemove() we have: if (sp-remove){ ierr = (*sp-remove)(sp,vec,sp-rmctx); } PetscFunctionReturn(0); } Any good reason for not CHKERRQ(ierr) after calling the userd-defined

most efficient way to use local CSR matrix?

Hmm, this should not happen. The matrix should be identical in both cases (note the initial residual is the same in both cases so they may be identical). Here's one more thing you can try. In the same routine create TWO matrices; one each way, then use MatAXPY() to take the
