If you got no output at all, then I suspect something must be wrong with
the scheduling system you are using. However, it is possible that you
and I have different ideas of what the phrase "no ouptut was produced"
means. Can you run the jobs outside of the scheduling system, and/or
verify that that you indeed have no mdout file?

It's not clear to me how you got a "md_error" file if you received no
output. Maybe it would help to give the exact commands you are using to
run the jobs.
It is also quite common to have to carry out minimization, and
somethings even the intial steps of equilibration, on a CPU. This can
be especially true if your initial structure is a bad one (with lots of
clashes) or if the initial density is far from the one you will finally
get (usually 1 gm/cc.)
It's very hard to tell which of these many possibilities (or none of
them) might apply to your situation.
