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

[Brainf]

Dear Martin Losch,

Unlimit did't work

OC 3% limit
cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       unlimited
coredumpsize    unlimited
memoryuse       8285840 kbytes
descriptors     200
vmemoryuse      unlimited
threads         1024
OC 4% unlimit
OC 5% limit
cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       unlimited
coredumpsize    unlimited
memoryuse       unlimited
descriptors     2500
vmemoryuse      unlimited
threads         1024
OC 6%./mitgcmuv1440x720x24
Killed
 

Now grid 100x580x24 succeed, grid 100x600x24 was failed ,
So I think 100x580x24 is the highest resolution. 
Maybe the resolution 1440x720x24 need more than 8GB RAM.
Does insufficient memory caused this problem?
Who knows  the RAM requirement of the resolution 1440x720x24?
