Hi,

1) The prefix is not hte path to the library but he path to the mpi install directory with its subdirectories bin, lib, include ...

2) Yes using the parallelisation is interesting on your machine when you are running a single caclulation. There is no (almost) way you can feed the other core with abinit when using the single threaded version. Moreover this is absolutely  not managed by the cpu and will not be so in near future.

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!
