Overall System Status:
IDL (Interactive Data Language) is a complete computing environment for the interactive analysis and visualization of data. IDL integrates a powerful, array-oriented language with numerous mathematical analysis and graphical display techniques. Programming in IDL is a time-saving alternative to programming in FORTRAN or C. You can explore data interactively using IDL commands, then create complete applications by writing IDL programs.
IDL may be downloaded locally, installed from DVD, or downloaded directly from Exelis. However, without a valid license, it will only operate in a seven-minute demo mode. The IDL VM (Virtual Machine) is a free runtime execution environment that can be used to execute IDL programs compiled using the full product.
Linux and Mac workstations with an AFS client installed may directly run IDL from our central servers. No local installation is needed other than some symbolic links for convenience.
The College has a small number of floating licenses available. The network license file is available at the local download link. Single licenses are much more expensive than bulk licensing. Please contact Research Computing if you are considering purchasing a private license. Student licensing is also available.
The floating licenses are valid for all versions from 5.0 (possibly earlier) up to the current version. The versions installed in AFS and available to UNIX workstations and central systems are summarized in the table below. In general, the default version on any particular platform is the latest that can run on that platform. Other available versions can be run by appending the version number (e.g., idl71).
The main IDL reference manuals are distributed as PDF files. They are available with each local installation, or from Exelis' web site. In addition, the idlhelp application has all of the reference material. Idlhelp does not require a license.
There is a local mailing list, firstname.lastname@example.org, for dissemination of information on licensing, new version installs, bug reports, etc.
The list archives and subscription information are available on the Web; see Archives of IDL-USERS@LISTSERV.DARTMOUTH.EDU. All IDL users are encouraged to subscribe to this mailing list.
