Re: New prerequisites to support multi image COARRAY in gfortran


Hi FX,

we don't really do. You can use other MPI implementation as well, albeit not all
features are implemented in all the others. For failed images support we needed
the fault tolerance support for MPI, which I see only in mpich from 3.2 on. The
other MPI implementations publicy available do not support ft at the moment. So
as soon as they do in their stable versions, we might give the user more choice.
