[MITgcm-support] tiles vs processors

[Martin Losch]

Chris,
something I never quite understood: Why do we have the capability for 
multiple tiles per processors (the bi-bj-loops)? The only reason I see 
is the cubed sphere grid. Are there any other situations in which it is 
advantageous to have more than one tile per processor?

As far as I can see the bi,bj indices do not say anything about 
processor ID (how could they?), which is the reason why Ed's 
mnc_assembly only worked with multiple tiles but not with multiple 
processors.
