EuroSys 2023 Shadow PC

October 4, 2022 / / 0 Comments

Young system researchers, e.g., Ph.D. students and PostDocs, can now apply for the EuroSys 2023 Shadow PC until October 12th.

A Shadow PC is meant to allow young researchers to obtain insight into the review process of major conferences. Typically, the review process of a big conference like EuroSys is rather intransperrant to young researchers. Therefore, it isn’t easy to understand what requires excellent research work to be accepted.

In a shadow PC (shadowing the programm commitee), young researchers actively review the research papers submitted to the conference. In EuroSys, papers submitted to the conference will also be assigned to members of the shadow PC for review with the permission of the authors. In addition, the shadow PC will determine and discuss its own ranking of submitted papers. Although the outcome will and must not impact the decision of the conference program committee, the discussion allows the researchers to obtain in-depth experience in the review process. Moreover, the reviews will also provide, in many cases, additional helpful
feedback to the authors.

Conference Visits at DEBS and SIGCOMM

September 9, 2022 /

After a long time of virtual conference events, our distributed systems research team had finally the opportunity to participate in physical meetings.

Two highlight this summer where our team attended and contributed were

  1. The conference 16th ACM Conference on Distributed and Event-based Systems (DEBS) in Copenhagen
  2. ACM SIGCOMM, the flagship annual conference of the ACM Special Interest Group on Data Communication (SIGCOMM), this year located in Amsterdam.

Three contributions at the ACM DEBS conference

At DEBS our team was present with three contributions on improving the performance of stream and event processing systems.

„Travel Light – State Shedding for Efficient Operator Migration” is a cooperation with the University of Oslo, with Espen Volnes , Thomas Plagemann and Vera Goebel. (University of Oslo). The paper looks into the combination of state shedding in combination with operator migration to improve the utility of detected events.    
The work of “Window-based Parallel Operator Execution with In-Network Computing” was presented by Bochra Boughzala.  It proposes a novel P4-based in-network computing model that can enhance the parallelization degree of event processing systems by utilizing the capability of programable network switches.    
In the Poster and Demo track Pratyush Agnihotri presented with “PANDA: Performance Prediction for Parallel and Dynamic Stream Processing” his idea on better performance modelling over heterogenous compute resources by building on zero-shot learning models.
