Are you calling VecRestoreArray when you are done inserting the values?

Yes, I'm calling VecRestoreArray, but I realized now that I exported the
vectors to Matlab
before doing that. Apparently that worked anyway for the CPU, but when using
the GPU
it didn't. If I call VecRestoreArray before exporting then everything works
fine on the GPU
as well. Thanks for
In most circumstances, you can and should interlace in some form such that each
block in fieldsplit is distributed across all ranks. If you interlace at scalar
granularity as described, then each block needs to be able to do that. So for
the Stokes equations with equal order elements (like
What if I use Codeblocks to run petsc? Would I still need to reinstall petsc or
the Cygwin installation will work?
Thanks

In the block matrices documentation, it's stated: "Note that for interlaced
storage the number of rows/columns of each block must be the same size" Is
interlacing defined in a global sense, or a process-local sense? So
explicitly, if I don't want the same size restriction, do I need to ensure
that
The above commands worked but I get an error message when I include petsc.h in
Visual Studio. The error message is "Cannot open include file: 'petscconf.h':
No such file or directory

If you need to use PETSc from Visual Studio - you need to follow instructions
at
https://petsc.org/release/install/windows/#installation-with-microsoft-intel-windows-compilers
[i.e install with MS compilers/MPI - not cygwin compilers/MPI]
Also check "Project Files" section on how to setup
Thanks for the tips!
The suggested settings for GAMG did not yield better results,
but hypre worked well right away, giving very good convergence!
A follow-up question then (I hope that's ok; and it could be related to GAMG
not working, I'll check that). Once everything was running I discovered
Hi all,
I'm looking for a small laptop which I'll be using (also) for small scale
PETSc (KSP & SNES) simulations. For this setting performance is not that
important, but still, I wonder if the community has any experience with AMD
Ryzen CPUs (specifically 5 Pro 6650U) CPUs compared to Intel i7
