[MITgcm-devel] multiple ptracers with divided adjoint

[Matthew Mazloff]

Hi Patrick,

Just to follow up on this issue -- the problem has to do with the size  
of the tapelevel files -- so its machine limitations, not the code.

For my setup I can run with up to  PTRACERS_num =  6 -- then at   
PTRACERS_num =  7 the outer tape level files get too large and the  
model poofs.

-Matt
