DUMP=nn.nn

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.
