Re: Memory allocation failure

Hi Lin,

The problem is that you are creating an array that's larger
(2371719168) than 2^31-1 (2147483647), which is the limit for NCL.

Since you sent me your script and data, I'll take a look offline and
see if we can work around this. I think we can, as the calculations
look like they can be done one piece at a time.
