About Me

My Name is Roni Häcki

I'm a PhD student at the Systems Group at ETH Zürich under the supervision of Prof. Timothy Roscoe since December 2015. I graduated from ETH Zürich in 2015 with a MSc in Computer Science with specialisation in Distributed Systems.

I'm part of the Barrelfish team. Barrelfish is a research operating system driven by the two problems of scalability for multi- and many-core systems and heterogeneous system hardware. Barrelfish treats a single machine as a distributed system. In consequence, techniques of distributed systems can be applied. Currently the Barrelfish team is working on extending Barrelfish to rack-scale systems

My current key interest is in how to manage the network as a resource within a rack-scale system. Within a rack-scale system fast communication links blur the line between machines, letting it look different from a traditional network. In a rack-scale system, the information about an applications network resource requirement as well as the underlying hardware is available. This additional information can potentially be incorporate into routing and congestion control decisions.
