Floating point error while running wrfhydro with mpirun

Postby ishitadg » Thu Mar 15, 2018 12:17 pm

Hi I have successfully compiled wrf_hydro (NoahMP) using gfort dmpar configuration. I am now trying to run the compiled executable wrf.exe with mpirun or mpiexec that keeps throwing the following warning message.
The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL

Anybody knows the cause and effect of this warning? Is it a gfort error? How can I get rid of this?
All outputs are getting generated and nothing else seems to be wrong with the output log. Here is the output log:
