Hello,

Is it possible to call within a D driver program library functions which are
programmed in C/C++ with the message passing interface (MPI)? I want to write
a program which makes use of the ParMetis library
(http://glaros.dtc.umn.edu/gkhome/metis/parmetis/overview).

Supposing it is possible, to compile and run C/MPI programs, wrapper commands
are used, such as mpicc and mpirun. What would be done in D?

Thank you,
Dominic Jones

Looks like MPI is just another C interface. You just need to write binding for
it and call it.

It is possible and I suppose everything not passing and retrieving messages
would be done in D. There is probably a bunch of work involved in converting
the headers, but there isn't any reason D can't call into MPI.
