Charm++ parallel programming system

[Jozsef Bakosi <jbakosi AT gmail.com>]

Hi Sam,

I'm also interested in more information regarding Fortran support.

In particular, the Fortran90 bindings manual says "you cannot define Chare and Group types". Does that mean, Charm++ groups are not supported using Fortran?

Thanks,

Jozsef

Hi Niel,

Charm++ provides limited support for Fortran90, and you can find the manual below. The example f90charm programs in charm/examples/charm++/f90charm/ all compile and run, but this interface has, I think, seen very limited use. Adaptive MPI, our implementation of MPI on top of Charm++, provides Fortran bindings too.

Hello,

Your FAQ page indicates limited support for Fortran and suggests
contacting this email for further information.

I was turned on to Charm++ through an enthusiastic colleague who has
been experimenting with it in some research C++ codes.  My interest is
in large-scale multiphysics (PDE) codes (e.g., https://github.com/truchas)
I'm interested in undertaking a serious investigation of charm for those
types of algorithms, however I am unabashedly a Fortran person and
would like to discuss with someone where charm stands with respect
to Fortran and whether it would really be a viable path to pursue.  My
interest is in Fortran 2003/2008 and its object oriented features.

Thanks,
  Neil
