Hi,
Obviously, you do not submit your calculations on a queue , but you run them locally on your computer.
nohup , will prevent your calculation from stopping , if you exit the terminal window, for example.
Take a look at the new files that have been created,e.g in job.last . you can see how many scf iterations have been performed, and how close convergence is.
You can also view the scf steps in graphical window (if you have xmgrace installed) by typing : cgnce job.last
It will be much better, if you run some examples first as shown in tutorial.
If your molecule is too big, then of course the calculation will take more time.
1) as a start, you can use a smaller basis set , e.g : def-SV(P)
2) take advantage of the RI approximation. (RIDFT is 10 times faster than normal DFT)
3) run in parallel.
Theory is explained in the manual. But if you need deep understanding, you should read the relevant papers or books. I would say that the Turbomole manual is very well written compared with manuals from other QM packages.
Anyway, it is a matter of taste.
good luck,
Andreas
