Run Ncview on the Cluster¶
Overview¶
- Running Ncview on the cluster follows the same general steps as any interacitve job. The steps are:
- Set up VNC session
- Load Ncview's dependent modules then load Ncview
- Run Ncview
- This guide will run through loading
ncview/2.1.2
and will include a walkthrough using some example data - The example data we will be using is a model of the Antarctic Ice sheet. Data is from the U.S. Antarctic Program Data Center
- Data file: netcdf-a1.nc.
- Check out the file transfer guide if you need assistance transferring the file to the cluster.
Set up VNC Session¶
- Please see the VNC guide for instructions on how to set up the Interactive VNC session
Load Ncview¶
- Open a terminal in the vnc window by clicking top left
Applications
>System Tools
> scroll down toterminal
- All commands here on will be typed in terminal in VNC
- Ncview depends on many other programs to run including,
gcc
andhdf5
. - For any program, to see available versions run
module avail <program name>
- Load all the dependent modules and then load Ncview with the following commands:
module load gcc/4.9.0
module load hdf5/1.8.19
module load netcdf
module load ncview
Run Ncview with Example Data¶
- Run Ncview with
ncview <.nc filename>
- To visualize the Arctic Ice Sheet data with
Ncview
, enter the folder where you have placed the data in and runncview netcdf-a1.nc
- A window with multiple options should pop up:
- Select a variable such as "bedrock" to display the model
