Is there any reason you can't use the most recent version of PETSc4py? The
one you are working with is several years old

Hi Hong,
Thanks for the advice. I could not install petsc4py with the --with-petsc4py=1
option, which gave me an "No rule to make target 'petsc4py-install'" error when
I ran "make install". That was why I needed to install petsc4py separately
after the PETSc was installed.
Best regards,
It seems that you installed petsc4py separately. I would suggest to add the
configure option --with-petsc4py=1 and follow the instructions to set
PYTHONPATH before using petsc4py.

Hi Matt,
Please see the following screenshot. Yes, I exported the PETSC_ARCH variable
before running the script. Note the "Invalid MIT-MAGIC-COOKIE-1 key" string is
related to the X server and in all Python printout, not on PETSc.

Can you show the
Hi Stefano,
Sure, please see the following. The PETSC_ARCH field is empty in the printout
despite the fact that it was set to 'arch-linux-c-opt' in the shell.
{'PETSC_DIR': '/home/pesun/.emopt', 'PETSC_ARCH': ''}

Yes, petsc4py does the right thing. This is probably. Picking up the wrong
PETSc arch.
Peng, can you please run this?
import petsc4py
petsc4py.init()
print(petsc4py.get_config())

Lisandro,
PETSc is compiled for single. Does petsc4py respect this, or does it always
use double for getArray() and friends?
Thanks,
Matt

Hello,
I am using KSPGMRES.
I was surprised to see DIVERGED_BREAKDOWN as well, which is why I thought
there could be some grid issues.
However, other preconditioners were able to retrieve a satisfactory
solution (PCGAMG, PCGASM, PCLU MUMPS).
Is there maybe a problem size for which boomerAMG
First send configure.log so we can see the setup.
Thanks,
Matt

Hi Mat,
Yes, you are right. I have tried both ways and they all work fine. the code
snippet in previous post is fine. I had some issue with other parts of the
code, that led to the unexpected results.
Thanks,
Feng
