[ncl-talk] Question on parallelism

[Dennis Shea]

It is not clear what you mean by "using parallelism in NCL"
What "driver script?"
What do you mean "output to files?"

You must be much clearer in what you have done and what you want as a
result.

A simple test script

   klev = 14
   ntim = 120   ; example 120 months
   nlat = 100
   mlon = 200
   u    = random_normal( 20,10,(/klev,ntim,nlat,mlon/))
   t     = random_normal(-10, 3,(/klev,ntim,nlat,mlon/))

   U    = *dim_avg_n_Wrap*
<http://www.ncl.ucar.edu/Document/Functions/Contributed/dim_avg_n_Wrap.shtml>
(u,1)
   printVarSummary(U)
   T    = *dim_avg_n_Wrap*
<http://www.ncl.ucar.edu/Document/Functions/Contributed/dim_avg_n_Wrap.shtml>
(t,1)
   printVarSummary(T)

Variable: U
Number of Dimensions: 3
Dimensions and sizes*: [14] x [100] x [200]*


Variable: T
Type: float
Total Size: 1120000 bytes
            280000 values
Number of Dimensions: 3
Dimensions and sizes: *[14] x [100] x [200]*
