Towards efficient code generation for exposed datapath architectures
Full text linkCoarse-grained reconfigurable architectures and other exposed datapath architectures such as transport-triggered architectures come with a high energy efficiency promise for accelerating data oriented workloads. Their main drawback results from the push of complexity from the architecture to the programmer; compiler techniques that allow starting from a higher-level programming language and generate code efficiently to such architectures robustly is still an open research area. In this article we survey the known main sources of challenges and outline a generic processor architecture template that covers the most common architecture variations along with a proposal for a common code generation framework for such challenging architectures
Reviewing inference performance of state-of-the-art deep learning frameworks
No full textDeep learning models have replaced conventional methods for machine learning tasks. Efficient inference on edge devices with limited resources is key for broader deployment. In this work, we focus on the tool selection challenge for inference deployment. We present an extensive evaluation of the inference performance of deep learning software tools using state-of-the-art CNN architectures for multiple hardware platforms. We benchmark these hardware-software pairs for a broad range of network architectures, inference batch sizes, and floating-point precision, focusing on latency and throughput. Our results reveal interesting combinations for optimal tool selection, resulting in different optima when considering minimum latency and maximum throughput
Exploiting specification modularity to prune the optimization-space of manufacturing systems
No full textIn this paper we address the makespan optimization of industrial-sized manufacturing systems. We introduce a framework which species functional system requirements in a compositional way and automatically computes makespan optimal solutions respecting these requirements. We show the optimization problem to be NP-Hard. To scale towards systems of industrial complexity, we propose a novel approach based on a subclass of compositional requirements which we call constraints. We prove that these constraints always prune the worst-case optimization-space thereby increasing the odds of nding an optimal solution (with respect to the additional constraints). We demonstrate the applicability of the framework on an industrial-sized manufacturing system
