Hi,
I think that you need to use the magical keyword “-dm_plex_gmsh_mark_vertices” for that

Dear Petsc team,
I want to load a .msh file generated using
PETSc hashing is done by leveraging the great package khash. Take a look at
include/petsc/private/hashtable.h and hashijkey.h for how we use kash to
automatically generate the code for a particular key. Just make your tolerance
smaller than the smallest diameters of your cells.

I don't think you want to hash floating point values, but I've had a number of
reasons to want spatial hashing for near-neighbor queries in PETSc and that
would be a great contribution. (Spatial hashes have a length scale and compute
integer bins.)

Good Afternoon,
Is there a structure within PETSc that allows storage of a value using a triple
similar to PetscHMapIJSet with the key using a struct{PetscScalar i, j, k;}?
I'm trying to access mesh information (the shape function coefficients I will
calculate prior to their use) who's values I
Dear Petsc team,
I want to load a .msh file generated using Gmsh software into the DMPlex
object. There are several things I would want to clarify, but I would like to
start with "Physical tags".
If I have defined "Physical Points", "Physical Surface", and "Physical Volume"
in my .geo file,
Suggest attaching text logs (copy/paste) - instead of screenshots.
Try:

Dear PETSc developer,
I use the following commands to configure petsc, but errors occur:

What sort of problem are you solving? Algebraic multigrid like gamg or hypre
are good choices for elliptic problems. Sparse triangular solves have horrific
efficiency even on one GPU so you generally want to do your best to stay away
from them.

Unfortunately, ILU(3) is not something that runs well on GPUs so ideally,
we should find a preconditioner that works well in terms of iteration count but
also runs well on GPUs. You can start by saying a bit about the nature of your
problem. Is it a PDE? What type of discretization?

Hey!
I am using PETSC in Fortran code and we apply the MPI process to
parallelize the code.
At the moment, the options that have been used are
-ksp_monitor_true_residual
-ksp_type bcgs
-pc_type bjacobi
-sub_pc_type ilu
-sub_pc_factor_levels 3
-sub_pc_factor_fill 6
Now, we want to use multiple GP

Hello all,
I am wondering about the right datatype to use for Hypre routines
in a Fortran code.
The Hypre manual provides a conversion table from C to Fortran on
page 80

but the small example that f
