IDL (Interactive Data Language) is a product from ITT Visual Informations
(ITTvis). IDL enables in-depth data analysis through
industry-leading visualization. This easy to learn, cross-platform,
application development software is relied on by analysts and engineers
around the globe. IDL's interactive, high-level language can help you
make discoveries and display your solution.
IDLat LLNL includes four licenses for theAdvanced Math
(AMS) package, two on the OCF and two on the SCF
networks. Note that IDL for Mac OS X does not support AMS or ISML.
. Links to the latest version exist in /usr/local/bin.
Settings: To setup your PATH and any other needed environment
variables, type use idl .
Coyote and Catalyst libs:
When you run idl
LC machines, you will also get the Coyote and Catalyst libraries added
to your IDL_PATH. See the Coyote web
IDL for UNIX can be used with one of two different interfaces. Starting
IDL with the idl command begins a
traditional IDL session using a simple text command line interface. If
you are running the X window system, IDL can also be started with the
idlde command, which invokes a
convenient multiple-document interface called the IDL Development
To use theAdvanced Math
(AMS) routines that are available with IDL Analyst,
start up IDL in the manner shown above. Calling one of the IDL AMS
routines will cause an IDL Analyst license to be checked out to you
until you quit IDL. LC has 2 licenses for AMS on the OCF and two the
Play nice with licenses!
1) Please do not hold onto IDL licenses overnight ("hoarding") unless
you are actually using them -- hoarding licenses creates artificial
scarcity and encourages further hoarding by others. It's a vicious
2) If you are using multiple licenses, and we run out of licenses,
please consider releasing one or two so that we are not out any more.
How to get "extra" "free" licenses: An important quirk
of IDL licensing is that IDL checks out only one license (six tokens)
per node/DISPLAY, no matter how many instances of IDL you run on that
node. This can be confirmed easily by running them by hand and checking
the license server records. So if you get 16 CPUs on one node, each
with 4 cores, you might be able to make good use of as many as 64
copies of IDL, using only a single license! Please ask
email@example.com for more details.
Older versions are available using dotkit.
To run an older version, type use
is the version number with
no spaces or periods (e.g. 82
version 8.2). See the graphics software
for a list of the versions available on the machines. Another
way to check is to use dotkit's tab completion feature: type use
and hit the tab key twice quickly and wait for
dotkit to show you the versions. Once you issue the "use" command, your
PATH will be set to get the version you specify. For more information
about dotkit, call the LC Hotline at 422-4531.
From the IDL command language prompt, you can get online help by typing
a question mark.
At the UNIX shell prompt, the following commands are available:
IDL Online Guide:
You can install IDL on your local workstation. IDL and installation
instructions can be downloaded from exelisvis.com
. You will need to create a free web
account on IDL's website to download the software. Click on the "My
Account" button in the upper right of their website to create or access
your account. Once you have logged into their web page and clicking "My
Account," you will see a download link in the middle of the page.
Select "IDL" from the "Select Your Product" popup, then choose the Full
Install package for your platform. The software is available for Linux,
Mac and Windows. The IDL Analyst and IMSL libraries are not available
on OS X as of July 2012.

If you have an account on the LC platforms, you can use the LLNL LC
site license to process data generated on Livermore Computing
resources. To access the LC license, the LC IDL license file must be
placed on your local machine. The license file can be copied from
any LC machine where IDL is installed If you do not have an LC account,
then please contact the Hotline to obtain one. Once you have downloaded
this file, you can simply place it into the license subdirectory of the
ITT installation and rename it to license.dat . On a Windows machine, the license
directory is typically C:\Program Files\ITT\license.
Alternatively, you can tell IDL about the LC license during
installation. Download the license file to your desktop, then rename
the LC license file to something ending with ".dat" or ".lic" and tell
the License Wizard where the file is. The License Wizard runs during
installation and can be found in the IDL installation directory after
install. This is (idl81/bin/ittlicense
for Linux/Mac, or on Windows, Start Menu
--> All Programs --> IDLx.x --> License Wizard to
activate the license. In the License Wizard, choose "install license
you have received" and navigate to your downloaded and renamed license
