Hi,

Your question looks sibyllin so I apologize in advance if my answer is
completely out of your matters.
Abinit is parallelized using mpi. In order to run a parallel
computation, you usually have to :
1) compile abinit with mpi support;
2)(sometimes) set up approriately your input;
3) run the compilation using the appropriate mpi scripts (comming with
your mpi installation) together with abinit.
From you question I guess that you may be missing step 1 and 3. To
compile abinit with mpi support, have a look at the output of
"configure --help" in your abinit sources root directory. And for step
3 you may want to try a tutorial on running mpi calculations; those
can be found on the websites of mpi implementations like openmpi or
mpich. Basically, running a parallel calculation can be as simple as
issuing the command :
mpirun -np 1024 abinit < input.files > log. But depending on your
computers setup it can be a little bit more tricky.

regards

PMA
