Graph Convolutional Networks (GCNs) are pivotal in extracting latent information from graph data across various domains, yet their acceleration on mainstream GPUs is challenged by workload imbalance and memory access irregularity. To address these challenges, we present Accel-GCN, a GPU accelerator architecture for GCNs. The design of Accel-GCN encompasses: (i) lightweight degree sorting stage to group nodes with similar degree; (ii) block-level partition strategy that dynamically adjusts...

The growth of the Machine-Learning-As-A-Service (MLaaS) market has highlighted clients' data privacy and security issues. Private inference (PI) techniques using cryptographic primitives offer a solution but often have high computation communication costs, particularly with non-linear operators like ReLU. Many attempts to reduce ReLU operations exist, they may need heuristic threshold selection or cause substantial accuracy loss. This work introduces AutoReP, gradient-based approach lessen...

The proliferation of deep learning (DL) has led to the emergence privacy and security concerns. To address these issues, secure Two-party computation (2PC) been proposed as a means enabling privacy-preserving DL computation. However, in practice, 2PC methods often incur high communication overhead, which can impede their use large-scale systems. this challenge, we introduce RRNet, systematic framework that aims jointly reduce overhead MPC comparison protocols accelerate through hardware...

In the acceleration of deep neural network training, GPU has become mainstream platform. GPUs face substantial challenges on GNNs, such as workload imbalance and memory access irregularities, leading to underutilized hardware. Existing solutions PyG, DGL with cuSPARSE, GNNAdvisor frameworks partially address these but traffic is still significant. We argue that drastic performance improvements can only be achieved by vertical optimization algorithm system innovations, rather than treating...

Recent years have witnessed a variety of applications gaming video coding, while how to improve the coding efficiency has been relatively under-explored. The state-of-the-art standard, Versatile Video Coding (VVC), adopts Reference Picture Resampling (RPR) which allows variation frame resolutions in encoding/decoding. great flexibility supported by RPR motivates us develop bidirectional quality impulse based guidance scheme, an effort fully exploit potential coding. design philosophy...

Video transcoding, which is a long-standing problem in video coding, can be used for variety of applications including bit rate conversion, format conversion and resolution conversion. In this paper, we present an effective transcoding solution from the popular previous generation coding standard, High Efficiency Coding standard (HEVC), to Versatile (VVC) latest developed by JVET. VVC enjoys much better efficiency compared its ancestors at expense higher encoding complexity. To facilitate...
