Bug with Grid Nudging under MPICH

Postby greg » Mon Sep 12, 2011 6:55 pm

Hi there,

I've noticed that with Grid nudging enabled there is inconsistent behaviour between running real.exe under MPICH and running it in a serial fashion.

In particular, using MPICH the wrffdda_d01 input file produced by real.exe has the 'old' fields (U_NDG_OLD, V_NDG_OLD, ...) set to 0.

I am running these tests using mpich2-1.3.2p1, Intel fortran compiler 11.1.
