Dear all,

       I am trying to optimize (scf calculation) the metal nanosheets. I am getting the following error:

running on 32 nodes

distr: one band on 1 nodes, 32 groups

--------------------------------------------------------------------------

mpirun has exited due to process rank 4 with PID 6668 on

node localhost.localdomain exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in

the job did. This can cause a job to hang indefinitely while it waits

for all processes to call "init". By rule, if one process calls "init",

then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".

By rule, all processes that call "init" MUST call "finalize" prior to

exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be

terminated by signals sent by mpirun (as reported here).

Can anyone help me? Your suggestions may help me a lot?

Thanking you.
