No, there is no way to make a single NCL script use multiple
processors. This is something on our list to look into.
As Dennis Shea stated in a recent email:
http://www.ncl.ucar.edu/Support/talk_archives/2009/1195.html
"Multiprocessing: It is not done from the NCL level. The user can
spawn multiple jobs to run on different CPUs from (say) a C-shell
script. Of course, if you have only one data channel per cpu to a
common memory, the different processes will still have IO
'conflicts' when reading/writing to a common (shared) memory."
