TSKSESF2 — Insufficency of Processor to Task semantics.

  • Key: TSKSESF2-8
  • Legacy Issue Number: 3712
  • Status: open  
  • Summary:

    The specification of Task under section 2.2.1 identifies and distinguishes between Independent and Dependent Tasks and distinguishes between the behaviour expected from data centric resources as distinct from process centric resources. Furthermore the specification implies that the state of a Task is a function of the state of the processor in combination with the state of used resources (data state). Under the specification the processor argument to a Task is defined as an AbastractResource, however, an AbstractResource does not provide semantics supporting notions of process oriented state or notions dealing with dependence or independence relative to an associated task (other then task to processor relationships). For interoperability between different domains an abstract processor interface is required which exposes as a minimum (a) a distinction between processors that control Task state as distinct from processors that are independent of Task state, (b) semantics enabling propagation of processor state to a associated Task, (c) interfaces enabling to interoperable location, instantiation and activation of a processes, and (d) semantics supporting the association of the role of consumed and produced resource relative to a processor (e.g. ability to distinguish two consumed workspace supplied as consumed resources to a "copy" processor where one resource is the workspace to be copied and the second workspace is the destination workspace).
