Recompiling mpich seems to have done the trick. Right now I am using abinit 
5.4.4p and I will try to upgrade to 5.8.3.

Thanks for all the quick help.

You get this problem because of an inconsistency between serial and
MPI compilers.

Basically, your MPICH installation uses gfortran, which you can check
by typing: "mpif90 -showme". If you want to use xlf, you should
recompile it accordingly.

I don't know which version you are using, thus I can just advise you
to compile a more recent version of Abinit, since a lot of progress is
currently being made on the support of MPI at several levels.

Best regards,

Yann.
