Abstract

Project B3 proposes novel techniques and concepts for hardware and software building blocks to enable power- and energy-efficient MPSoCs at high performance within the invasive computing platform.

The first funding phase has focused on hardware-support for i-let/thread assignment along with adaptive power gating to enable standard IP-based MPSoC platforms to benefit from the invasive computing and programming paradigm in a power-efficient way. We introduced the Core i-let controller (CiC) which, in collaboration with the iRTSS, performs thread assignment based on application requirements and current hardware status. In order to increase the energy-eficiency of the invasions we developed the concept of Virtual Power Gating.

The second funding phase focused on power/energy efficiency with respect to the dark silicon problem. Within the paradigm of invasive computing, the objective has been to ensure that invaded claims remain thermally reliable using design-time application and hardware models.

In the third funding phase, our goal is to become independent of design-time-generated hardware and application models. The techniques developed in the first and second phase heavily rely on the availability and correctness of these models, which is often not the case. To achieve independence, we develop novel power/thermal management techniques based on self-awareness and machine learning. This allows to either obtain hardware and application models at run-time, or to operate without any explicit models.

Synopsis

The ever-increasing transistor integration and the observed limits on voltage scaling for next-generation technology nodes result in high power densities and temperatures on many-core systems, which are the causes behind the emerging dark silicon problem. Particularly, when a common cooling solution is used for subsequent technology nodes (i.e. the cooling costs are kept constant), all the cores on a chip can no longer be simultaneously active at the nominal operation levels without violating the chip’s thermal constraints. Such an effect challenges the viability of further cost-effective technology scaling, as this could lead to diminishing performance gains for smaller technology nodes.

Traditional power and thermal management techniques generally rely on a certain a-priori knowledge of the chip’s thermal model, as well as information of the workloads/applications to be executed (e.g. transient and average power consumption). Nevertheless, this a-priori information is not always available. Furthermore, it cannot reflect the spatial and temporal uncertainties and variations that come from the environment, the hardware, the input data, or from the workloads/applications. The InvasIC system level power/thermal manager has to consider such uncertainty and variability. However, resource and power management techniques that are statically optimised are unlikely to achieve the best performance when the workload characteristics are changing. We aim to achieve high performance and power/energy efficiency through a novel self-aware and machine-learning based InvasIC power management system.

Approach

Our scientific work involves exploring the trade-offs between the resulting temperatures and power densities for different workload scenarios, the average and peak power consumption, the overall energy consumption, and the achieved performance, in which the following objectives are pursued:

  • Objective 1: Improving power/energy efficiency under power density and temperature constraints without relying on design-time application and hardware models.
  • Objective 2: Run-time model refinement and online estimation of power density and temperature for invasive computing.
  • Objective 3: Develop an adaptive and self-aware system for run-time power, energy, and thermal management, where application/hardware models are obtained at run time or where we use model-free techniques.
