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.<br>

you wrote is not OK. You have to first create the KSP, next extract<br>
the PC with KSPGetPC, and then configure the PC to use HYPRE+BoomerAMG<br>
<br>
To be sure you are actually being using hypre, add -ksp_view to command line.<br>
