[MITgcm-devel] SIZE.h matters on Columbia for CS510?

[Hong Zhang]

Dear all,
last lime we reported a problem (attached here:
---------
Something has happened to code from checkpoint59l to current head 
branch, which makes it impossible to restart CS510 code.  Any clues 
where we should look and what chekpoints to test?
Job crashes on third time step with

> WARNING: r*FacC < hFacInf at       3 pts : bi,bj,Thid,Iter=   1   1   
> 1       218
>  e.g. at i,j=  65  85 ; rStarFac,H,eta = -1.237739  4.755480E+03

> STOP in CALC_R_STAR : too SMALL rStarFacC !

---------
We found this problem is related to the config of SIZE.h and w2_e2setup.F
We tested s216t_85x85/SIZE.h_216, s1800t_17x51/SIZE.h_450, and 
s216t_85x85/SIZE.h_54.
They all failed and caused the same error as mentioned above.
But the config of s1350t_34x34/SIZE_270.h is workable.
For s216t_85x85/SIZE.h_54 we further switched off the optimization
(in Makefile setting FOPTIM =) but it has the same problem.
We checked the output @second timestep
but didn't find obvious overlap problem.
Does anyone have any clue?
