[Mitgcm-support] threading and mpi

[mitgcm-support at dev.mitgcm.org]

Alistair and Chris,

on the NEC SX-6 I would like to run the model in threaded mode, meaning 
within a node (of 8 processors with shared memory) I would not use mpi 
but simply a copying mechanism between tiles. What do I have to do to 
achieve that? Simply specifying nPx and nPy and compiling without mpi? 
Or nSx and nSy?

And: How would I mix that communication, i.e. using threads within a 
node and mpi across?

-Arne
