[MITgcm-support] namelist; end of file reached without finding group

[Matthew Mazloff]

Yeah, I think this is a poorly behaved mpi barrier issue -- I think I  
wrote about this earlier

when you have many processors some will over-write scratch before  
others have finished using it

until it gets fixed by someone, I suggest having each processor write  
its own scratch -- so you can put the following routines in your code  
folder and make sure you
#define TARGET_BGL
in your CPP_OPTIONS.h

-Matt

if you want try googling for this -- my last email may give more info
