Hello all,

I recently installed vasp5.4.1. on my xenon work station using gfortran.

After a completion of calculation,using vasp_std (checked with scf/relax/optic) the following Note appears.

Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DENORMAL

What does this note indicate? Is it an error? Is that something to do with my compilation?

Following is my make.include

# Precompiler options
CPP_OPTIONS= -DMPI -DHOST=\"IFC91_ompi\" -DIFC \

Can anyone suggest and help?

Thank you
