keep in mind that you are looking at a system that is much larger (by an
order of magnitude) than proteins that Amber is more typically used for.
The mailing list will look at problems, but you should expect to have to
work out lots of problems for yourself, and to learn how the code works.
I encourage you also to think hard about what you plan to learn about this
system (given that you won't be able to do much sampling), and whether some
smaller piece of it might not serve your purposes equally well.

You will need to find a machine with at least 600 MBytes of physical (or
virtural) memory.

Add a "lastist=<number>," to your &cntrl namelist, and re-run. You may have
to experiment to see what value you need, but it will need to be larger
than the default one.

The master node is noting that there is not enough memory for the job, and it
is stopping the whole run.

Limited by available memeroy.
