Hi,
The rst file from the previous simulation should be your next starting point for the next simulation in pmemd.cuda.
There is nothing to be worried about.

The (default NetCDF) restarts from pmemd.cuda are written with full
double precision, just like the restarts from CPU pmemd; there really
is no "more accurate" than that. Is there a specific reason you are
concerned about restart files from pmemd.cuda? Have you seen strange
behavior etc?

Typically the former is a soft link to the latter. The SPFP refers to
the single-precision/fixed-precision model - for more details see
