GPGPU-WG KnowledgeBase GLUE2 Profile ExecutionEnvironment

The ExecutionEnvironment class describes the hardware and operating system environment in which a job will run. It represents a set of homogeneous Worker Nodes, so if a computing system contains nodes with significantly different properties there MAY be several ExecutionEnvironment instances. This implies that it should be possible to request a specific environment when a job is submitted. The ExecutionEnvironment MAY refer to virtual rather than physical machines.

As well as attributes describing a typical node, the class gives summary information about the size and usage of the set of nodes which posess those properties. However, there is no way to relate these to the information in other entities, e.g. it is not possible to know which jobs in a given ComputingShare are running on which ExecutionEnvironment.
