You have not given any input source (-a or ::: or ::::), so GNU
Parallel assumes you want to provide your arguments on stdin.

... and if stdin is a terminal, it will tell you that the input is
read from the terminal, and that this is likely not what you want.
I do not know that 'loadtest' contains, but if it contains lines that
each can be run in parallel then you can do:
parallel :::: loadtest
/Ole
