NameD3.5.1 Preliminary report on run-time management

This deliverable is the first report of Task 3.5, dealing with Run-Time Resource Management (RRM). The goals of Task 3.5 are to develop a lightweight architecture for RRM in tightly constrained systems and sample run-time resource managers for both COMPLEX use cases 1 and 2. In addition to the RRM architecture, Task 3.5 will also develop services and optimization heuristics to be supported by the RRM for alleviating the burden of the application programmer.

The goals of this first deliverable are to provide a preliminary vision of the work to be performed in Task 3.5. The content of this deliverable is organized as follows:

  • Section 2 defines the abbreviations used in the deliverable.
  • Section 3 overviews the challenges to be fulfilled by the RRM in future embedded computing.
  • Section 4 gives a preliminary description of the RRM architecture being developed in Task T3.5 and of the RRM interfaces with the applications, the user, and the platform. This RRM follows a distributed and hierarchical approach: it consists of a Global Resource Manager (GRM) at the platform level, communicating with Local Resource Managers (LRMs) at the IP core level. To alleviate the run-time decision making, a design-time exploration is performed.
  • The resulting relevant information is stored in GRM databases, characterized in Section 5.
  • Section 6 describes the list of commands that allow the GRM to interact with the applications.
  • Section 7 describes the run-time optimization heuristic that will be developed and integrated in the GRM. This heuristic selects an application configuration in order to maximize its Quality of Service (QoS) while meeting its deadline and respecting the energy budget of the platform and the target platform autonomy.
  • Section 8 describes the power controller of HW blocks to be used as LRM.
  • Sections 9 and 10 introduce both sample RRMs for COMPLEX use cases 1 and 2 respectively.
  • Finally Section 11 presents how the GRM efficiency will be analyzed.
