The IA-32 Execution Layer (IA-32 EL) is a software package for running IA-32 applications on Itanium® architecture-based platforms.
Most current versions of Linux* operating systems for Itanium architecture include IA-32 EL. Please refer to vendor documentation to determine if IA-32 EL is included in the version that you are using and if any actions are required to turn on IA-32 EL.
If you are building a customized Linux operating system for Itanium architecture-based platforms, then this distribution enables you to add IA-32 EL to your operating system.
