Show us the line from your benchmark.sh which contains ps and we may be able to help you.

its clear that you are using just ps where there is no terminal attached to that.

running ps - would give the process associated with the current tty from which 'ps' is executed.

after executing nohup script &
are you disconnecting the sesssion from which script is invoked, if that is the case,

issuing ps would give no associated terminal - here you have to use ps with options like ps -ef

You are going to hate this answer, but it means that process running "ps" has no controlling terminal.

An interactive session has a controlling terminal that is used to deliver Ctrl-C, hangups and basic job control among other things.

Background tasks should not really be associated with a controlling terminal because they are not interactive.
