Hello,
Postel3D does not work in parallel, so I wonder what happens, I don't have this when I run it with Perl.
In fact it seems that for unknown reasons (Python scripts ?) you call the subroutine P_INIT from library parallel, while it should be P_INIT from library paravoid. A bypass of this problem would perhaps consist of taking program homere_postel3d in a fortran file for your case and changing the .true. to .false. in the call to bief_init. If it does not work, another solution would be taking subroutine bief_init and changing the call to p_init into :
NCAR=0
CHAINE=' '
IPID=0
I hope that helps,
JMH
