Re: PETSc + HYPRE

Hi, Lisandro. I must apologize for not answering. I read your email and changed my code, but then I went through a different path. I'm trying to call the preconditioner from the command line, without any mention to it in the source code. It should take a couple of hours to get some results and then, if it doesn't work, I'll change the code.


Thank you very much.

Sorry for my insistence, but... Did you see my previous mail? The code
you wrote is not OK. You have to first create the KSP, next extract
the PC with KSPGetPC, and then configure the PC to use HYPRE+BoomerAMG

To be sure you are actually being using hypre, add -ksp_view to command line.
