we would like to request a transition of the numerical stack
libraries, namely:
- PETSc and petsc4py, from 3.24 to 3.25
- SLEPc and slepc4py, from 3.24 to 3.25
- mumps, from 5.8 to 5.9
- adios2, from 2.11 to 2.12
petsc has some reproducibility regressions, as well as some autopkgtest
issues. Can you take a look?
I've been monitoring it. I'm really not sure what to do about it.
The issue is not something obvious like a build date or random order of
build flags.
The libraries are simply getting their starting memory addresses with
different numbers, why would that happen?
And the fortran modules (*.mod) are getting their entries recorded in
random order.
I don't think petsc is doing anything deliberately to generate
non-reproducibility like that.
Help welcome.
