[ncl-install] running ncl on a compute node of a cluster

[Po-Lun Ma]

Hi Folks,

Happy New Year!

I have a question: I have always run NCL on the management node of a 
cluster without any problem. However, it is sort of slow when I need to 
run several NCL scripts at the same time while other people are also 
using the management node to compile a program or do some other work. 
So, I am attempting to submit a NCL script to the compute node of a 
cluster.

However, the cluster I am using does not make every compute node to load 
all libraries to make the compute node simpler and therefore faster. 
That causes a problem because the compute nodes do not have all the 
libraries required for running NCL, for example, the X11-related 
libraries. In fact, since I only need to run a NCL script to read in 
data, use the built-in functions to do some calculations, and produce a 
plot (ps file) or a ASCII file, I actually do not need to have X11 
libraries, but I do not know how to "turn off" X11 features in NCL.

Can someone help me with submitting a NCL job to a compute node (that do 
not have X11 libraries) of a cluster?

Thanks for your help.
