Restart files are written automatically at two hour CPU time intervals
to allow a long job to be restarted if the job is terminated
catastrophically. To change the frequency of dump, set DUMP=nn
to request a dump every nn seconds. Alternative forms are
DUMP=nnM, DUMP=nnH, DUMP=nnD for a dump every nnminutes, hours, or days, respectively. DUMP only works with geometry
optimization, gradient minimization, path, IRC,
DRC, and FORCE
calculations. It does not (yet) work with a SADDLE calculation.
