About

I intend to craft platforms with which humane people can control the fire of computing.

My research focuses on creating new tools for understanding and controlling the run-time behavior of complex computer systems.

News

I deactivated my Twitter account @hiyangxi after the Mad King Elon Musk acquired Twitter, I am @xiyang@mastodon.social on mastodon.

I left University of Sydney and joined Twitter as a software enginner.

Joined Professor Willy Zwaenepoel's research group at University of Sydney as a postdoc.

My PhD. thesis SHIM and Its Applications.

Gave a talk (slides, and video) at Linux.conf.au 2019 about how to monitor tail latency across layers of system components.

Joined Confluent as a software engineer working on the distributed performance evaluation framework.

Source code for the Elfen scheduler paper.

ANU news about the Elfen scheduling.

Elfen scheduler for improving datacenter utilization.

Dan mentioned the SHIM profiler in his blog.

SHIM Profiler is open source now.
