Hello,
I am using mpic++ to create a program that combines c++ and f90
libraries. The libraries are created with mpic++ and mpif90.
OpenMPI-1.2
was built using gcc-4.1.1. (below follows the output of ompi_info. The
final linking stage takes quite a long time compared to the
creation of
the libraries; I am wondering why and whether there is a way to speed
up.
Thanks for any inputs.
