SoCRATES, the System-on-Chip Resource AdapTivE Scheduling, is a DRL scheduler specializes in scheduling SoC jobs to heterogeneous resources showing the state-of-the-art run-time performance. The Eclectic Interaction Matching technique matches the individual state-action tuple with the reward received by the system clock frequency.
Our recent paper, DRL for SoC: Myths and Realities, investigates the feasibility of neural schedulers for the domain of SoC resource allocation through extensive experiments and comparison with non-neural, heuristic schedulers.
The scheduler runs on the System-on-Chip (SoC) framework. The simulation is developed under DS3 framework, which is a high-fidelity system-level domain-specific system-on-chip simulation environment. The system provides plug-and-play run-time policy and energy/power modules. The main objective is to optimize performances (i.e., run-time latency, power dissipation, and energy consumption). To enable ease-to-use deep reinforcement learning algorithms, we run scheduling algorithms using DS3Gym simulator built with Gym environment for SoC-level task scheduling. The overall diagram of DS3 and the comparison of job characteristics are illustrated in below.

Requirements
- CPU or NVIDIA GPU, Linux, Python 3.6+
- PyTorch, Python packages; instructions for installing dependencies are followed.
- Python environment: We recommend using Conda package manager
conda create -n socrates python=3.6
conda activate socrates- Install DS3Gym framework and required Python dependencies
pip install torch numpy
pip install -r requirements.txt
pip install -e .This repository supports heuristic and DRL schedulers. To reproduce the results, one can execute the following commands corresponding scheduler.
Currently, we support training agents for CPU only. It takes approximately 1~2 hours for completion.
python run_socrates_scheduler.py
python run_heuristic_scheduler.py
python run_scarl_scheduler.py
python run_deepsocs_scheduler.pyA DS3Gym framework allows users to customize different configurations. The supported settings are listed in config.py:
--resource_profile: A list of resource profiles--job_profile: A list of job profiles--scale: Job frequency (lower scale for fast injection rate)--simulation_length: A total simulation length for one running episode--scheduler_name: A name of scheduler (ETF/MET/STF/HEFT/random/SCARL/DeepSoCS/SoCRATES)--max_num_jobs: A length of job queue--run_mode: A choice of mode in simulation execution (runfor standard DS3 framework /stepfor DS3Gym framework)--pss: A choice of mode for enabling pseudo-steady-state
This repository implemented some of well-known heuristic schedulers: MET, ETF, EFT, STF, and HEFT. To run simulations with these schedulers, you can simply give scheduler's name as an argument when running the python code.
The presented repository provides DRL-based schedulers: SoCRATES, DeepSoCS and SCARL. Detailed information for each scheduler are described in below.
SoCRATES (IEEE ICMLA, 2021)
SoCRATES, the System-on-Chip Resource AdapTivE Scheduling, is a DRL scheduler specializes in scheduling SoC jobs to heterogeneous resources showing the state-of-the-art run-time performance. The Eclectic Interaction Matching technique matches the individual `state-action' tuple with the reward received by the system clock frequency.

}DeepSoCS (Electronics, 2020)
DeepSoCS is a first DRL-based scheduler applied in DS3 framework. By extending Decima architecture, DeepSoCS rearranges the given tasks using graph neural networks and policy networks. Then, it applies a greedy algorithm to map tasks to available resources. This mechanism similarly operated with HEFT algorithm.
