Data Systems Researcher

I am an Associate Professor of Data Science and Computer Science at the University of Virginia. My research covers a range of topics including distributed systems, serverless and cloud computing, storage systems, operating systems, and high-performance computing. My current research focuses on designing scalable, high-performance, and easy-to-use computer systems that manage and process huge volume of data.

Currently I am working on: (1) Serverless and FaaS: improving serverless computing using a end-to-end approach that cuts across the entire ecosystem stack: (stateful) applications, middleware, platforms, and low-level OS/HW; (2) Sys4ML: building better (computing and storage) systems for large-scale ML applications; (3) ML4Sys: improving systems software and infrastructure management by using learned/learning/data-driven approaches; and (4) Data Reduction: rethinking data reduction techniques for large data-intensive applications;

I am the recipient of an NSF CAREER Award (2021), an Amazon Research Award (2021), a Meta Research Award (2022), the IEEE CS TCHPC Early Career Researchers Award for Excellence in HPC (2022), and a Samsung GRO 2023 Award (2023). Prior to joining UVA, I was an Assistant Professor of Computer Science at George Mason University, from 2017 to 2022. I received my Ph.D. degree in Computer Science from Virginia Tech, working with Dr. Ali R. Butt. During my Ph.D. I spent two summers at IBM Research Almaden in 2013 and 2014, and six months at Dell EMC Princeton Office in 2015.

Serverless Parallel Computing: Scaling out Python parallel programs (e.g., Dask applications) on FaaS without worrying about tedious cluster management. Wukong uses a new decentralized scheduling technique, which decentralizes resource orchestration to each individual serverless function, thereby enabling high elasticity and high scalability.

FaaS Platform Management: A highly scalable container provisioning framework that can provision thousands of 10+GB serverless function containers with just a few seconds. FaaSNet is currently deployed at Alibaba Function Compute.
[ATC’21]: [GitHub] [Alibaba Cloud Blog]
Serverless Function OS Scheduling: Linux CFS is not ideal for short-lived serverless function workloads. This project rethinks OS scheduling to minimize function turnaround time.
[SC’22]: [GitHub] – [ATC’24]: [GitHub]
Storage for Deep Learning: A common practice in deep learning training is to randomly shuffle all training samples epoch by epoch. With SHADE, you can cache the most important training samples without losing training quality.

Wukong: A Scalable and Locality-Enhanced Framework for Serverless Parallel Computing

Benjamin Carver, Jingyuan Zhang, Ao Wang, Ali Anwar, Panruo Wu, and Yue Cheng

In Proceedings of the 11th ACM Symposium on Cloud Computing 2020

Abstract arXiv PDF Code Talk

Executing complex, burst-parallel, directed acyclic graph (DAG) jobs poses a major challenge for serverless execution frameworks, which will need to rapidly scale and schedule tasks at high throughput, while minimizing data movement across tasks. We demonstrate that, for serverless parallel computations, decentralized scheduling enables scheduling to be distributed across Lambda executors that can schedule tasks in parallel, and brings multiple benefits, including enhanced data locality, reduced network I/Os, automatic resource elasticity, and improved cost effectiveness. We describe the implementation and deployment of our new serverless parallel framework, called Wukong, on AWS Lambda. We show that Wukong achieves near-ideal scalability, executes parallel computation jobs up to 68.17X faster, reduces network I/O by multiple orders of magnitude, and achieves 92.96% tenant-side cost savings compared to numpywren.

TiFL: A Tier-Based Federated Learning System

Zheng Chai, Ahsan Ali, Syed Zawad, Stacey Truex, Ali Anwar, Nathalie Baracaldo, Yi Zhou, Heiko Ludwig, Feng Yan, and Yue Cheng

In Proceedings of the 29th International Symposium on High-Performance Parallel and Distributed Computing 2020

Abstract arXiv PDF

Federated Learning (FL) enables learning a shared model acrossmany clients without violating the privacy requirements. One of the key attributes in FL is the heterogeneity that exists in both resource and data due to the differences in computation and communication capacity, as well as the quantity and content of data among different clients. We conduct a case study to show that heterogeneity in resource and data has a significant impact on training time and model accuracy in conventional FL systems. To this end, we propose TiFL, a Tier-based Federated Learning System, which divides clients into tiers based on their training performance and selects clients from the same tier in each training round to mitigate the straggler problem caused by heterogeneity in resource anddata quantity. To further tame the heterogeneity caused by non-IID (Independent and Identical Distribution) data and resources, TiFL employs an adaptive tier selection approach to update the tiering on-the-fly based on the observed training performance and accuracy. We prototype TiFL in a FL testbed following Google’s FL architecture and evaluate it using the state-of-the-art FL benchmarks. Experimental evaluation shows that TiFL outperforms the conventional FL in various heterogeneous conditions. With the proposed adaptive tier selection policy, we demonstrate that TiFL achieves much faster training performance while achieving the same or better test accuracy across the board.
