Yes, I know... but this time I am almost sure about this point. At least I
am sure I compiled the paralell version of the program, but I am not sure
if I compiled it in the right way...

Yes it prints "pararell version (MPI)" . I have run the paralell version
of cpmd in the same cluster, althought the compilation steps were
performed by a wiser guy... Anywary, I will take a look at startup.f90
