Introduction
NCAR Command Language (NCL) is a set of subroutines which uses GKS software as a base. It is distributed by the National Center for Atmospheric Research (NCAR) (Boulder, Colorado) and allows designing visualization graphics (traced curves, histograms, level curves, 3D visualization, cartographic contours, etc.).
Installed version
- NCL is only available in parallel version 6.6.2 and with an environment combining gcc/9.1.0 et intel-mpi/19.0.4.
Usage
The ncl
product can be accessed with the module command.
Note that only one version of ncl
is available:
$ module avail ncl
ncl/6.6.2-mpi
Moreover, it can be used in only one environment, mixing gcc/9.1.0
with intel-mpi/19.0.4
, as is shown in the display
command output of module
:
$ module display ncl ------------------------------------------------------------------- /gpfslocalsup/pub/modules-idris-env4/modulefiles/linux-rhel7-x86_64/ncl/6.6.2-mpi: module-whatis {NCL is an interpreted language designed specifically for scientific data analysis and visualization. Supports NetCDF 3/4, GRIB 1/2, HDF 4/5, HDF-EOD 2/5, shapefile, ASCII, binary. Numerous analysis functions are built-in.} prereq gcc/9.1.0 conflict ncl Available software environment(s): - gcc/9.1.0 intel-mpi/19.0.4 If you want to use this module with another software environment, please contact the support team. -------------------------------------------------------------------
To use ncl
, you just need to load the corresponding module:
$ module load ncl Loading ncl/6.6.2-mpi Loading requirement: gcc/9.1.0 intel-mpi/19.0.4 $ module list Currently Loaded Modulefiles: 1) gcc/9.1.0 2) intel-mpi/19.0.4 3) ncl/6.6.2-mpi
