Dear All,
I'm new to abinit and not an expert of cpu architectures.
I'm compiling abinit on my Dual Core AMD Turion 64 bit.
I've a problem in finding the MPI libraries during the configure
process: I've installed both open-mpi and mpich. The configuration is
made
with the switch --enable-mpi=yes --with-mpi-prefix="path of the
library".
The configure script does not find a usable mpi library but I'm sure
that the static mpi library (.a) is present in the indicated path.
Moreover I've a general question: is it advantageous to use a
parallelized code on a single dual core cpu? Or the calculation load
between the
two cores is managed internally by the cpu itself?
Thanks a lot!
Mauro Sgroi.
