Large data processing

All-
 I have a netcdf file with 1 variable dimensioned: 23423 x 109 x 134
[time,lat,lon].

NCL runs out of memory on computing dim_avg wrt time (I have 2GB available
and 2 GB swap space). I know I can do dim_avg in 2 chunks. But what about
computing the standard deviation, dim_stddev? Does anyone have a workaround?

I tried using nco to do this but my machine came back with an malloc error,
and another machine with 4GB of memory and 4GB of swap also returned the
malloc error.
