"out_dt must be a multiple of the NOAH_TIMESTEP" error message

[alessioderango]

Current Behavior

Using NOAH offline compilation, when we try to run the model with more than one mpi processes, even if OUTPUT_TIMESTEP is multiple or equal of NOAH_TIMESTEP, we got "read_rt_nlst:: out_dt must be a multiple of the NOAH_TIMESTEP" error message.

Possible Solution

We tried to solve the problem and we noticed that in this new version inside module_namelist.F at line 188 there is an if statement which interrupts the execution. After a short debugging, we found that if we move the if statement after all broadcast communications (line 502), the problem is solved.
