Hi,

I am trying to load in an array (the array is 362x332x75x1032 (34.7GB)), which exceeds maximum array size preference (16.0GB). How do i go about loading it in.

It is a variable which is part of a .nc dataset

Memory is cheap. Get more memory.

I'm sorry, but if you want to work with big data, you will often need sufficient capabilities to handle that data. No matter what, working with huge arrays, lacking sufficient will be slow. So your next question will be, how can I make my code run faster. Again ... get sufficient memory. Or, solve smaller problems.

This is for my masters dissertation, so unfortunantly upgrading my memory isn't an option

@Sophie

Did the professor assign the hardware and say "you must run it on this hardware" ?

If not, then:

if it is your own hardware, then there is always the option of upgrading it
if it is university hardware, then there is always negotiating with the university to obtain an upgrade
