Dear friends:
I am looking for a Parallel iterative solver package for Windows system written in fortran.
Could you please give me some suggestions.
Regards

Most of the major packages are in C (PETSc and Hypre). LIS also is in C, but has the AMG coded in Fortran. Trilinos might even be in C++ (I don't know, but certainly it is not in Fortran).

The only package I know of being in Fortran is http://www.mld2p4.it/

But I suspect that the Windows support is near to 0. Not that it is impossible to make it work (gfortran is nowadays available in multiple flavors), but I suspect the dependencies to be more troublesome. Maybe someone else can help here.

PETSc is written in C but can be called from a fortran code.

What do you mean by parallel ? Are you referring to distribuited (MPI) or shared memory (OpenMP). Unless you have a cluster MPI won’t do much for you so I guess you are using a desktop system. If so, you can use GNU Fortran and install OpenMP. That is not very efficient because that will require installing Cygwin which is a Linux emulator. If you have a bigger budget then you can try intel Fortran which is a great compilers. The latter has a ice feature that parelizes section by itself with very good performance compared to OpenMP in GNU Fortran
