[MITgcm-support] How to calculate the RAM requirement?

[Brainf]

Dear Matthew Mazloff,


I test  1440*720*24 grid

size mitgcmuv1440x720x24

                .bss	2164500888	271102208	271102208	
2500793 + 164467 + 2164500888 = 2167166148

Does this mean I need 2G RAM ?

I have 4G RAM, But can't run it for  1440*720*24 grid.
100*80*24 grid success.
