Sorry, I don't understand well what you are doing. When you speak of PBS I suppose that
you run your job with mpirun as well, but using a batch scheduler which does not need
human interaction (i.e. you submit a script to the queuing system of your cluster).
So, if your job runs with mpirun in interactive mode and not in batch mode, it could be a
problem in your batch environment setup: you have to check environment variables,
libraries, disk access and space, etc. etc. and maybe contact your system administrators...

Yes,the former read from pbs date ,the latter read from the input file .
But why the error will turm up use pbs ? How can I solve this problem ? Can you give me specific illustration about this ,I am not understand about this .Thank you very much !
Best regards

exactly in the same way as all problems are solved: observe,
experiment, think, make an hypothesis, verify...computer
problems are infinitely simpler than physics problems

Why not to get a userguide for a PBS ?
Different environmental settings will give rise to different behaviors of
your scripts.

Dear all
When I add external electric field to optimize the structure .It runs very very slower than not add the electric field , after 2 days ,the output file is still as following :

I don't know why after I add the electric field ,the speed of relax is so slow ?
Any advice will be appreciated !
