The ApplicationHandle class is an extension to ApplicationEnvironment for applications which need to be set up in some way before they can be used. For each supported setup method a string MAY be specified, the interpretation of which is specific to the method - in the simplest case this could just be a setup script to execute. A single Application MAY support multiple setup methods.
'''Note:''' The OGF Glue 2 Specification defines the ApplicationHandle_t as an open numeration, with values of:
* executable
* module
* Path
* softenv
'''Presently no information is published in the BDII that uses this Class'''. However, it may be seen as a very good way to correctly bootstrap the environment for the users job.

The Working Group shall define an EGI Community GLUE2 based standard that encapsulates and publishes data about the application software its environment required by Computational Accelerators.

There are two GLUE2 classes to consider here:

  • The ApplicationEnvironment, which is a significant extension to the GLUE1 GlueHostApplicationSoftwareRunTimeEnvironment.
  • The ApplicationHandle, a new class that can indicate how an to describe an ApplicationEnvironment instance can setup the software environment.

The GIP plugin glite-ce-glue2-applicationenvironment-dynamic produces ApplicationEnvironment data by converting the basic GLUE1 GlueHostApplicationSoftwareRunTimeEnvironment to a simple ApplicationEnvironment instance.


The ApplicationEnvironment is a GLUE2 class that describes the software environment in which a job will run.

  • Each Application is identified by a name.
  • These names are not defined by the schema, but should be assigned in a way that allows applications to be uniquely identified.
