Hi, I think maybe the problem is because the right to write on disk. In my memory, you can add  "umask" option to your environment file .bashrc, and then files created by abinip can be read and written by other machines.

Hello users,

I am having trouble running my input file on a cluster system with 4
processors; that's two two-processor machines. I'm quite a newbie at
abinitp.

I can see from the log file two worrying messages:

p1_7266:  p4_error: alloc_p4_msg failed: 0

which (after some other output) continues with

p2_6059:  p4_error: interrupt SIGx: 13
p2_6059: (955.289062) net_send: could not write to fd=5, errno = 32
mpiexec: Warning: tasks 0-1 exited with status 1.

Googling did not give me much help; except for that this may be a
mpiexec problem writing to disk(?) Has anyone had this problem or know
how to get round it?

I haven't had any trouble running the parallel tests / tutorials.

Thanks in advance.
Best,
        Toby
