`rocgdb` as one would do with `gdb` (`rocgdb` is literally `gdb` built with
extra AMD stuff (that stuff is either upstreamed or being upstreamed to gdb
BTW)). You can do it in batch mode as well so you can dump the logs from
each MPI process.

Greetings,
We have a test that has started failing upon switching from 3.5.4 to 3.6.0
(actually went straight to 3.6.3 but checked this is repeatable with
3.6.0). I've attached the matrix generated with -mat_view binary and a
small PETSc program that runs in serial that reproduces the behavior by

Arg, this came off bad, sorry. I meant, is there a particular publication
for which GAMG should be cited?
Maybe relevant pubs/bibtex could be added alongside the PETSc ones on the
PETSc webpage to help this? (Shame on me, but is there a relevant GAMG
publication?) It doesn't help with the disingenuous researcher not willing
to go the extra step of proper citation, but would certainly help someone

Hello,
Quick (and probably stupid) question: Does CHKMEMQ check *all* of memory
used by the program for corruption or just the memory PETSc allocated? I
have a code that I'm assigned to work on that doesn't use PETSc (yet),
but I was hoping to use this macro to track down what I think is a

Kind of a non-numerical question - sorry. I'm using PetscPrintf from

Hi Ben,
Here is the format I use in my .f90 modules. Note I do not know what
the standard is, but this "style" has worked with ifort, gfortran, g95

Is it possible to use

I'm developing some code and am using direct solvers (for the moment),
in particular MUMPS and SuperLU. I noticed that PETSc is not
preallocating the memory for it even though I specify maximum number of

Don't want to be rude and interject, but I looked at the unsteady.F file

Yes, example ex5f broke in the exact same way. Note the preceding c/c++

Has anyone had any experience using PETSc and gfortran together? My
