CESM1_2_1 restart test fails for SE dycore

Hi all,

I have performed a "restart test", i.e. checking if the results are the same for a 2 day simulation versus a 1+1 day simulation (write + read restart). The results are binary identical for a finite volume experiment
-res 4x5_4x5 -case test4messy_restart -compset F_2000_CN

but they diverge for SE:
-res ne16_ne16 -case test4messy_restart_se -compset F_2000_CN

model version is CESM1_2_1.

I would appreciate any feedback on this.

kind regards,
Andreas

This was on my own machine (g95 with openmpi on ubuntu) with g95 changes (see below). I just now repeated the same test on yellowstone, where it passes the test, so this seems to be g95-related, which is not officially supportet anyway. I will also perform the test on a IBM AIX next week, so unless this will fail I suggest to ignore this...Thanks, Andreasse/share/dimensions_mod.F90#ifndef __G95__
