All, I am running MPICH3 with program compiled with PGI Fortran. At the end of (successful) completion of the simulation, I am getting the following warnings for each node Warning: ieee_invalid is signaling Warning: ieee_denorm is signaling Warning: ieee_invalid is signaling Warning: ieee_denorm is signaling Warning: ieee_denorm is signaling Warning: ieee_denorm is signaling Warning: ieee_denorm is signaling Warning: ieee_divide_by_zero is signaling Warning: ieee_divide_by_zero is signaling Warning: ieee_denorm is signaling Warning: ieee_divide_by_zero is signaling Warning: ieee_underflow is signaling Warning: ieee_inexact is signaling Any suggestion if these warnings are harmful or on how to turn them off?
