[MITgcm-support] Limitation for Tile's dimensions

[Eli Biton]

Thanks, Martin and Constantinos
For now I'm using mpif90, which adding the flag  - mcmodel=medium did not solved the problem (the optFile I'm using is below).
Any suggestions (before moving to other compilers)?
Many thanks, Eli

GNU, PGI, Pathscale, Absoft and Intel compilers all accept - mcmodel=medium
which has to do with the addressing mode not the stack. You have to make
sure all the libraries you link with are also compiled with - mcmodel=medium
or - fPIC.
