I'm a graduate student at the School of Computing, University of Utah. Most of the time I work on Xen to implement time-travel for large distributed systems in Emulab. I moved to Utah from Kiev, Ukraine, where I was a graduate student at the Institute for Applied System Analysis at the National Technical University of Ukraine "Kyiv Polytehnic Institute" (Complete education history).

In Ukraine I worked with Leonid Ryzhyk. It was a wonderful and strong team. We were full of naive but interesting ideas. We spent several years working on E1 distributed operating system project.

Operating systems: new abstractions for building operating systems, virtualization, microkernels, distribution models, persistence, threading models, IPC mechanisms, applicability of lock-free algorithms to kernel structures.

Replay debugging: deterministic and non-deterministic replay debugging of large distributed systems.

Distributed systems: abstractions for next generation network operating systems

Development of a replay debugging environment for distributed systems consisting of hundreds of machines. Our time-travel system will run along with an experiment launched in Emulab and capture original execution of an entire network of virtual machines. In case of an error, a researcher will be able to rollback execution of the network to the point before the crash and inspect its state or debug it with a traditional step-by-step debugger. On each node we replay entire OS along with its running processes.

Emulab includes more than 350 PC nodes. Some 1500 users run experiments of size 1-300 nodes, on a first-come first-served basis. Demand far exceeds capacity, so Emulab provides a weak form of time-sharing. We would like to schedule Emulab experiments similarly to how OS schedules its processes. The Emulab scheduler could preempt low-priority or idle experiments, save the full state of entire network, and replace it with other experiments. The goal is that swapout/swapin must be transparent to the experiment, and except for scheduling delays, transparent to users. In the context of Emulab, this means that we are able to preempt large long running experiments without compromising the correctness of experimental results.
