[lammps-users] The group communication

Dear lammps users,
I have a group of particles (say water ) .I am doing parallel computation ( with 4 processors).Is there any command to communicate the positions of all the particles in a group(water) to all processors(4). I need all processors to have the positions of all particles in that particular group .
Where should i do that ,If I am doing DPD simulation ?

Thanks,

No, LAMMPS isn't setup to do that. It isn't a parallel
operation for one proc to know the coords of (potentially)
all other atoms in the simulation.
