NclMalloc error

Hello all,

I am trying to compute monthly anomalies for the CRU data(~2.5GB) using NCL version 6.1.0. I am using NCL installed through cygwin. However, I get the error
"fatal:NclMalloc Failed: [errno=12]
fatal: Error allocating -90600955556656555 bytes to read variable ..."

I realize this is the NCL memory limit error but I do need to work on the entire dataset. Is there any workaround this issue?

Regards,
Prajjwal
