Efficient Training and Deployment of Machine Learning on Distributed and Parallel Systems
We study how to improve performance and energy efficiency of machine learning workloads (including training and inference), how to make machine learning approachable by regular users (personalized machine learning), and how to make machine learning robust and secure.

Resource Management in Heterogeneous Computing
Heterogeneous computing uses more than one kind of processor and memory to achieve best performance and energy efficiency. The GPU-based system is an example of heterogeneous computing; The emerging non-volatile memory-based system is another example. Resource management in heterogeneous computing in our research includes data movement and placement in emerging architectures, and massive thread-level parallelism management on GPU.

Fault Tolerance in Large-Scale Parallel Systems
We study how to make the large scale parallel systems survive potential hardware failures and software errors without sacrificing system efficiency and effectiveness.
