What is the best method of ensuring good different seed vector values for the Fortran intrinsic procedure

random_seed()

corresponding to each coarray image in Fortran programs? Any help or suggestions is greatly appreciated. By "good", I mean seeds that do not result in highly correlated or identical pseudo-random sequences on different images.
