I change MasterSeed and nothing happens with MPI processes seeds

Dear all:

I’m using the Geant4 Version:_11.2 on Linux Centos+ gcc 10.3.

I’m running a user code combined with MPI capabilities, without hyperthreading.

I use the /mpi/setMasterSeed option to set up the master seed for all the processes that will run in parallel. In addition, I ask the code to print the RNG seed for each parallel process via the command /mpi/showSeeds.

The problem is that I change the Master Seed and processes seeds remain the same, and so the results of the simulation.

In short, I get the same simulation results after changing the master seed for the parallel processes.

Thanks in advance,
Mario
