Experience

Boost NVMe SSD Performance with Mediated Pass Through, 2017/02 -- Present

This project aims to improve the performance of NVMe SSD in the virtualized environment by leveraging the benefits of Mediated Pass Through. Especially, the project is currently implemented with VFIO-MDEV, and optimized with multiple approaches like polling mode.

Keyword: NVMe SSD, Mediated Pass-Through, VFIO-MDEV

Demon: Efficient in-Device MMU Virtualization in Mediated Pass-Through, 2016/07 -- 2017/02

Demon reuses the Guest in-device MMU as the 1st-dimensional translation and utilizes the system IOMMU to construct a 2nd-dimensional address translation. Demon is implemented with a prototype named gDemon which virtualizes GPU MMU and achieves up to 19 times the performance improvement.

Keyword: Device MMU, IOMMU, GPU, XenGT, Mediated Pass-Through

Cost-Efficient Negotiation over Multiple Resources, 2015/10 -- 2016/03

This project aims to solve the problem of multi-resource negotiation with considerations of both the service-level agreement (SLA) and the cost efficiency, taking advantages of reinforcement learning technology. This research paper is accepted by IWQoS 2017.

Keyword: On-demand Allocation, Multi-Resource, Reinforcement Learning
