[deal.II] Re: website petsc tutorial

[Jean-Paul Pelteret]

Hi Yi-Chung,

We typically update that documentation for the versions that we 
specifically test against, so unless the documentation was accidentally not 
updated then it is best to assume that the version mentioned on the website 
is the most recent version that is, to the best of our knowledge, 
compatible and bug-free when used with that specific release of deal.II. It 
might be the case that a newer version works with deal.II, but it may not 
be fully tested.

However, I will see if I can dig up some information on which was the most 
recent version of PETSc tested at that time, and double check if the 
documentation was up-to-date at that point or not.

Best,
Jean-Paul

Hi Jean-Paul, 

Thank you for explaining it. I have the question because the page shows 
deal.ii is compatible with petsc 3.6.0. As I may recall, 8.4.1 is 
compatible with 3.6.4, right? 

All best, 
YC Chen

[deal.II] Re: website petsc tutorial

Dear Yi-Chung,

Thanks for the information, but this is done by design (so there is no 
problem). 

At the time of the release of deal.II 8.5.0, the content linked to on  
http://www.dealii.org/8.5.0/external-libs/petsc.html 

would have been the most recent release that deal.II was certified to work 
with. If, in the months that have passed since the release of that version, 
a new version of PETSc (or any other 3rd party libraries) then we test it, 
patch the developer version of deal.II if necessary, and update the 
information on the developer site, in this case being
https://www.dealii.org/developer/external-libs/petsc.html
for PETSc. At the time of the next release, we take a snapshot of the 
information on the developer site and it becomes "frozen" for that release.

Does that make sense?

Kind regards,
Jean-Paul
