Running NCL on NCAR's Supercomputers
If you have an account on one of NCAR's supercomputers: blueice, bluevista, lightning, or tempest, and you want to run NCL, here's what you need to do:- Set the environment variable NCARG_ROOT to /usr/local
- Add /usr/local/bin to your "path" or "PATH" variable.
- Make sure NCARG_LIB is NOT set.
The above steps are ones that should be handled inside one of your .* files in your home directory, like ".cshrc" or ".profile".
For example, if you are running C-shell and you have a ~/.cshrc file, then you can set the NCARG_ROOT environment variable and add "/usr/local/bin" to your path by adding the following lines to the file:
setenv NCARG_ROOT /usr/local set path=(/usr/local/bin $path)or:
setenv NCARG_ROOT /usr/local setenv PATH /usr/local/bin:$PATHIf you are running bash shell and you have a ~/.bashrc or ~/.profile file, then you can set the NCARG_ROOT environment variable and add "/usr/local/bin" to your PATH variable by adding the following lines to the file:
export NCARG_ROOT=/usr/local export PATH=/usr/local/bin:$PATHNote that adding "/usr/local/bin" to your path/PATH variable must be done after this variable has already been initialized to something. You can also add "/usr/local/bin" to the original initialization of path/PATH.
