“…We compare our three thermal management strategies with a patterning mapping, and with a Multi-Objective Resource Management (MORM) approach [7]. Recent works on DTM use the patterning approach [12,13] in a known applications' set, without the support of remapping by migrating tasks.…”

“…For example, the management can frequently set PEs as active or dark at different moments to control the system power consumption under a power budget or below a critical temperature [6]. Recent proposals assume the system itself manages the adaptation, to increase its performance while keeping it within the physical limits of operation [7].…”

New technology nodes enable the integration of billions of transistors in a small silicon area by replicating identical structures, resulting in many-core systems. However, power density may limit the amount of energy the system can consume. A many-core at its maximum performance may lead to safe temperature violations and, consequently, result in reliability issues. Dynamic Thermal Management (DTM) techniques proposals guarantee that many-core systems run at good performance without compromising reliability. In this paper, we review recent DTM works, discussing their limitations, and propose new heuristics for thermal-aware application mapping and migration, using a hardware accelerator that enables temperature monitoring on systems with a large number of processing elements. Results show that using straightforward heuristics, with reactive actions based on runtime temperature monitoring, reduce the peak temperature in high workload scenarios (6.8%), and improve thermal distribution significantly on a large (8x8) many-core system.

“…Starting first with those that do not, there are a number of works on application-level runtimes that target either homogeneous or single-ISA heterogeneous platforms (such as Arm big.LITTLE architectures). This category includes works such as SPARTA [16], SOSA [15], SEAMS [31], and the work of Martins et al [14]. While each of these works explores highly interesting avenues in the area of application runtime design in their own right (such as the control theory-based approaches leveraged by SOSA [15] and SEAMS [31]), here, we prioritize discussion of works that address runtimes for multi-ISA or accelerator-rich architectures.…”

In this work, we present CEDR, a C ompiler-integrated, E xtensible D omain Specific System on Chip R untime ecosystem to facilitate research towards addressing the challenges of architecture, system software and application development with distinct plug-and-play integration points in a unified compile time and run time workflow. We demonstrate the utility of CEDR on the Xilinx Zynq MPSoC-ZCU102 for evaluating performance of pre-silicon hardware in the trade space of SoC configuration, scheduling policy and workload complexity based on dynamically arriving workload scenarios composed of real-life signal processing applications scaling to thousands of application instances with FFT and matrix multiply accelerators. We provide insights into the trade-offs present in this design space through a number of distinct case studies. CEDR is portable and has been deployed and validated on Odroid-XU3, X86 and Nvidia Jetson Xavier based SoC platforms. Taken together, CEDR is a capable environment for enabling research in exploring the boundaries of productive application development, resource management heuristic development, and hardware configuration analysis for heterogeneous architectures.

“…The proposed MPSoC model can estimate the energy required by a task. The average energy consumption of every processor instruction was previously characterized using the method described by Martins [2]. We compared four different application setups to determine the best configuration, considering energy consumption and response time for the task set.…”

“…The goal of the proposed environment is to integrate multiple simulators in a unique setup that covers physics, hardware, and software simulation of robots and vehicles. The environment will enable the evaluation of non-functional requirements such as energy/power consumption [2], and response time for robotics applications. Validation of the proposed environment is performed with an unmanned aerial vehicle (UAV) application in a quadrotor.…”

Multi-processor Systems-on-Chip (MPSoCs) have been proposed to tackle embedded systems' requirements due to their potential for low-power consumption and high scalability. These systems fit the needs of many application domains, including robotics and autonomous vehicles, in which reliability, performance, and timeliness are critical to operation. In this paper, we propose an integrated environment for the development of robotic applications targeting MPSoCs. The proposed environment eases the evaluation of non-functional requirements by combining cycle-accurate simulations from RTL models with behavioral simulations from robotics. We present a case study of the proposed environment in the context of a UAV (unmanned aerial vehicle) stabilization software, providing performance and energy estimations for different software implementations.
