GSL does *not* have built-in send and recieve functions for MPI.
MPI does *not* recognize any GSL types.
You certainly could use MPI to write functions which send and recieve
GSL objects.
You should take a look at
the Vector, Signal and Image Processing Library (VSIPL)
http://www.vsipl.org/
and also the
High Performance Embedded Computing Software Initiative (HPEC-SI)
http://www.hpec-si.org/
Verari Systems Software Inc. (formerly MPI software technology)
offers a VSIPL implementation (VSI/Pro).
http://www.mpi-softtech.com/
Eventually, there should be a parallel version of VSIPL and VSIPL++
based upon MPI.
The authors of
the GNU Scientific Library (GSL)
http://sources.redhat.com/gsl/
are exhausted now but might eventually be persuaded
to include parallel codes in their library.
