Hello PETSc Community,
I think I've found a bug -
Go to $PETSC_DIR/src/ksp/ksp/tutorials/
open ex5f.F90, and add the following line in MyKSPConverged(), say around
line 336:
call KSPConvergedDefault(ksp,n,rnorm,flag,dummy,ierr)
It should make sense why someone would want to do this - within a
parately - and use it with petsc.

Hi PETSc community,
I've been looking at using Spack to build PETSc, in particular I need to
disable the default metis/parmetis dependencies and use PTScotch instead,
for our software.
I've had quite a bit of trouble with this - it seems like something in the
resulting build of our simulator ends
seems to be no hint of the MD flag in any of the cmake files provided
with hypre, so it looks like the -MD flag is being added by the cmake Ninja
generator as a kind of default (and maybe in a confused way - why the -
instead of /?)
So the task now seems to be to convince cmake to stop doing this.
Hello PETSc Users/Developers,
A collegue of mine is looking into implementing an adaptive implicit method
(AIM) over
PETSc in our simulator. This has led to some interesting questions about
what can
be done with blocked matrices, which I'm not able to answer myself - does
anyone have
any insight?

Hello,
I'm working on getting a petsc build running on windows. One necessary
package to include is Hypre. I've been able to build Hypre seperately using
cmake, and confirmed that the library works
by setting up a VS project to run some of the example programs.
My attempted petsc build is being d
Hello all,
I am currently having to figure out a way to get petsc working on windows,
using compilers from the intel oneAPI package. This means new compiler
names, such as "icx" for the c compiler and "ifx" for the fortran one.
I see from the installation instructions, and from old notes from a

Hello all,
I've been having some configure failures trying to configure petsc, on
Ubuntu 20, when
downloading mpich.
This seems to be related to the use of
"#!/bin/sh"
found in the script
mpich-3.4.2/modules/yaksa/src/backend/cuda/cudalt.sh
/bin/sh in Ubuntu20 is dash, not bash, and line 35 of

Hello,
If we look at lines 2330-2331 in file baij2.c, it looks like there are some
mistakes in assigning the `sum..` variables to the z array, causing
the function MatMultAdd_SeqBAIJ_11() to not produce the correct
answer.
I don't have a good example program to demonstrate this yet - it's
current

re harvested and
this error is generated, so I can try to get a better idea about what is
going on?

where to start with getting this to work? I can
provide a lot more information
from the debugger if need.
Many thanks in advance,
