Well, when dealing with Fortran I also often encounter software which
cannot be changed or upgraded to a more modern style.
What was in my mind is to create an interface additional to what is already
there in petsc. So this should be compiled along with anyone's code if the
used ocmpiler supports

I don't think anyone will want to
Exactly, I personally look for:
1) type checking during the function calls. This helps also not looking
into the manual for every single petsc function call.
2) low level access to petsc data structure. For example in my own code I
already have my own hadnling of parallel vectors and matrices.

1. You really need to profile. Copying a vector is cheap.
You are right. Maybe I make a big thing for this copy in/out and it is
not that problematic or slow even for the whole 2D matrix. I have to test
it with a large one to see.
2. If you make your functions (to evaluate residuals, etc)
Hello All,
I am trying to use petsc with Fortran. The initial mechanism to use petsc
with FORTRAN77 that works fine. However, I found the Fortran 90 interfaces
difficult to work with. The very first issue is one has to recompile petsc
with the Fortran compiler in case different to the one which

Thank you for your answer.
It is not true that F2003 support is that limited: Gfortran, Intel Fortran,
Cray Fortran, IBM Fortran and PGI Fortran all support nearly full F2003.
Some other ones support the C portability of F2003 although not supporting
the rest.
