[QE-users] =>> PBS: job killed: walltime 172854 exceeded limit 172800 . how can i correct this error.

[Giovanni Cantele]

The error message means that either you submitted a job by defining a finite wall time
that has been exceeded (that is, you job would have required more time than required),
or that the default wall time il too small for jour job or else that the queuing setup has
a maximum wall time, that cannot be exceeded in any case.

In the first two cases, you should require a larger time for your job. In the latter,
the only solution is to restart your job several times, until it lasts.
Also consider that QE has a max_seconds variable (you can learn its usage
from the user guide) that allows you to setup a maximum execution time,
independently of the queuing system. In general you set max_seconds to
a time that is a bit smaller than the maximum wall time imposed by the
queuing system (if any). In this way the code exits smoothly before it is killed
by the queuing system. Indeed, abrupt killing might result in an incomplete
writing of the files necessary for subsequent restart.

As a general remark, messages posted to the forum are usually signed with affiliation.
Moreover, I think it is not that efficient to include the body of the message in its subject.
