    • An Analysis of Network-Partitioning Failures in Cloud Systems 

      Alquraan, Ahmed (University of Waterloo, 2018-12-10)
      We present a comprehensive study of 136 system failures attributed to network-partitioning faults from 25 widely used distributed systems. We found that the majority of the failures led to catastrophic effects, such as ...
    • An Analysis of Partial Network Partitioning Failures in Modern Distributed Systems 

      Alfatafta, Mohammed (University of Waterloo, 2020-01-03)
      We present a comprehensive study of system failures from 12 popular systems caused by a peculiar type of network partitioning faults: partial partitions. Partial partitions isolate a set of nodes from some, but not all, ...
    • Improving Cluster Scheduling Resiliency to Network Faults 

      Qunaibi, Sara (University of Waterloo, 2023-05-31)
      We present a comprehensive empirical study of the impact partial network partitions have on cluster managers in data analysis frameworks. Our study shows that modern scheduling approaches are vulnerable to partial network ...
    • In-Network Scheduling for Real-Time Analytics 

      Udayashankar, Sreeharsha (University of Waterloo, 2021-04-30)
      This thesis presents Bolt, a novel scheduler design for large-scale real-time data analytics. Bolt achieves the scheduling accuracy of modern centralized schedulers while supporting clusters with hundreds of thousands of ...
    • Leveraging Software-Defined Networking to Mask Partial Network Partitions 

      Alkhatib, Basil (University of Waterloo, 2021-08-11)
      We present an extensive study focused on partial network partitioning. Partial network partitions disrupt the communication between some but not all nodes in a cluster. First, we conduct a comprehensive study of system ...
    • Measuring the Performance of Code Produced with GitHub Copilot 

      Erhabor, Daniel (University of Waterloo, 2022-12-22)
      GitHub Copilot is an artificially intelligent programming assistant used by many developers. While a few studies have evaluated the security risks of using Copilot, there has not been any study to show if it aids developers ...
    • MECBench: A Framework for Benchmarking Multi-Edge Computing Systems 

      Naman, Omar (University of Waterloo, 2023-01-27)
      I present MECBench, an extensible benchmarking framework for multi-access edge computing. MECBench is configurable and can emulate networks with different capabilities and conditions, can scale the generated workloads to ...
    • A Network Integrated Design for Micro-scale Cloud Services 

      Abdel-hadi, Ashraf (University of Waterloo, 2022-05-25)
      We present Falcon, network-integrated scheduler for micro-scale services. Falcon follows a centralized scheduler design to achieve high scheduling efficiency and leverages modern programmable switches to lower the scheduling ...
    • Network-Accelerated Linearizable Reads 

      Takruri, Hatem (University of Waterloo, 2019-08-07)
      This thesis present FLAIR, a novel approach for accelerating read operations in leader-based consensus protocols. FLAIR leverages the capabilities of the new generation of programmable switches to serve reads from follower ...
    • Optimizing MPI Collective Operations for Cloud Deployments 

      AlSader, Zuhair (University of Waterloo, 2020-01-24)
      Cloud infrastructures are increasingly being adopted as a platform for high performance computing (HPC) science and engineering applications. For HPC applications, the Message-Passing Interface (MPI) is widely-used. Among ...
    • Soteria: An Approach for Detecting Multi-Institution Attacks 

      Zabarah, Saif (University of Waterloo, 2023-01-02)
      We present Soteria, a data processing pipeline for detecting multi-institution attacks. Multi-institution attacks contact large number of potential targets looking for vulnerabilities that span multiple institutions. Soteria ...
    • A Study of the Capabilities of Message-Oriented Middleware Systems 

      Al-Manasrah, Wael (University of Waterloo, 2023-01-27)
      We present a comprehensive characterization study of open-source Message-Oriented Middleware (MOM) systems. We devised a rigorous methodology to select and study 10 popular and diverse MOM systems. For each system, we ...
