Project 1: 

Performance evaluation of resource partitioning mechanisms on serverless applications

Abstract: Serverless cloud platforms host multiple tenant applications, each consisting of several small functions executing in one or more containers. The applications of multiple tenants may be colocated on a server, which multiplexes CPU and memory resources among the tenant applications. This sharing can lead to security concerns (namely side channel leaks of sensitive data) as well as high variability in application performance metrics (e.g,. latency and throughput). The goal of this project is to evaluate a resource isolation strategy for serverless platforms that allocates dedicated memory partitions to each tenant application and uses a predictable CPU scheduling strategy based on time division multiplexing (TDM). The project includes (but is not limited to) following tasks:

  • Understanding the hardware memory and cache hierarchy, as well as addressing mechanism
  • Understanding the operating system page coloring mechanism
  • Designing a memory and cache partitioning mechanism using a combination of OS and hardware techniques
  • Identifying candidate serverless applications for benchmarking
  • Configuring partitions for the serverless application benchmarks
  • Empirical evaluation of the application performance and server costs
  • Summarizing the results of the project in the form of an end-of-term report and a presentation in the lab

Students interested in working on this project must have done CPSC 213, CPSC 313 and be proficient in C/C++. Prior experience with kernel programming or serverless applications is desirable but not a requirement.

Work Setting:

  • On-site (on-campus)

 

Project 2: 

Analyzing microarchitectural side-channel vulnerabilities in serverless applications

Abstract: Many applications deploy serverless functions that may process sensitive information, such as personally identifiable information (PII) or credit card information. Despite isolating function execution in containers and encrypting the communication to/from the functions, function secrets could be leaked via microarchitectural side channels. Specifically, a function of a colocated adversarial application can monitor the execution time and cache access patterns of the "victim" function and infer the victim's secrets. The goal of this project is to identify serverless applications vulnerable to such side channel leaks via systematic side-channel experiments. The project includes (but is not limited to) the following tasks:

  • Background study on a class of microarchitectural side-channel leaks, namely cache-timing leaks
  • Collecting a dataset of serverless applications for analysis
  • Identifying secrets in the serverless applications
  • Implementing an automated program analysis tool to analyze serverless applications for secret-dependent execution patterns
  • Evaluating a well-known microarchitectural side-channel attack on potentially vulnerable serverless applications
  • Summarizing the results of the project in the form of an end-of-term report and a presentation in the lab

Students interested in working on this project must have done CPSC 213, CPSC 313 and be proficient in C/C++. Prior experience with javascript or serverless applications is desirable but not a requirement.

Work Setting:

  • On-site (on-campus)

Project 1: 

Byzantine fault tolerance in a Software-Controller Inverted Pendulum

A software-controlled inverted pendulum (see https://en.wikipedia.org/wiki/Inverted_pendulum for reference) is a cyber-physical system that requires continuous control to remain in a stable vertical position. Any problem with the control — software or hardware issues, even transient delays — will cause the pendulum to fall. We consider a software-controlled inverted pendulum as a representative example of more complex control systems in safety-critical applications, like inside cars and drones.

We have developed a testbed (see https://github.com/ubc-systopia/inconcretes/tree/physical_ivp for details) consisting of an inverted pendulum and a fault-tolerant quadruple-modular redundant system to control the pendulum. That is, we use four nodes to control the pendulum, which can tolerate a range of failures in one or more nodes.

However, with multiple nodes, there arises classic distributed systems failure scenarios, such as distributed agreement (consensus) in the presence of faults. These need to be solved in a manner that does not hinder with the resource constraints of the embedded platform (limited memory, limited network bandwidth, strict timing issues, etc.).

Student Responsibilities:

The students will be tasked with primarily low-level systems engineering, after spending some time brainstorming the design. They can expect regular interaction with me (at least weekly) and also support from me in terms how how to proceed with the project, assistance on technical questions, etc. Plus, they will also be able to spend their time in Systopia, have a desk in our lab, and participate in all social and academic group activities in Systopia.

Qualifications:

The goal of this project is to extend our existing work on crash fault tolerance in our cyber-physical testbed to Byzantine fault tolerance. While the research corresponds to designing software systems primarily, and the hardware challenges in our testbed are mostly sorted, we expect the candidates to be comfortable working with the various electro-mechanical components in our testbed. We expect the candidates to ideally have some background on distributed systems, e.g., in the form of CPSC 416. It is preferred, but not expected, that the candidate also possess some knowledge of real-time systems or operating systems scheduling. The software system is built using C++. Hence, C/C++ skills are strongly recommended.

Work Setting:

  • Expected on campus, some online work allowed

 

Project 2: 

Redesigning distributed real-time systems for heterogeneous MPSoCs

Heterogeneous embedded platforms, such as the Zync UltraScale+ MPSoC, are increasingly being used to program safety-critical cyber-physical systems applications. We are especially interested in their real-time capabilities, as they possess separate real-time processors (ARM Cortex-R family) in addition to application processors (ARM Cortex-A family). The goal of this project is to identify design patterns for fault-tolerant real-time distributed systems on such heterogeneous processors. Specifically, given an implementation of a fault-tolerant distributed real-time system — such as systems like IGOR (https://par.nsf.gov/servlets/purl/10282881), In-ConcReTeS (https://arpangujarati.github.io/pdfs/rtss2022_paper.pdf), or Cascade (https://haeberlen.cis.upenn.edu/papers/cascade-rtas2020.pdf) — how can we refactor its design to work on a distributed system where each node is a heterogeneous platform?

The project will require understanding and working with open-source implementations of existing research prototypes, redesigning and reimplementing them (if needed), and porting them to the new platforms. The secondary goal will be an empirical evaluation of the new system design against the old one.

Student Responsibilities:

The students will be tasked with primarily low-level systems engineering, after spending some time brainstorming the design. They can expect regular interaction with me (at least weekly) and also support from me in terms how how to proceed with the project, assistance on technical questions, etc. Plus, they will also be able to spend their time in Systopia, have a desk in our lab, and participate in all social and academic group activities in Systopia.

Qualifications: 

We expect the candidates to ideally have some background on distributed systems, e.g., in the form of CPSC 416. It is preferred, but not expected, that the candidate also possess some knowledge of real-time systems or operating systems scheduling. Most software systems of interest are built using C++. Hence, C/C++ skills are strongly recommended.

Work Setting:

  • Expected on campus, some online work allowed

Caroline Lemieux

Project: Unit Tests from Exploratory Tests

Abstract: The gold standard for software testing are scripted unit tests that can be automatically replayed using frameworks such as pytest and JUnit. The advantage of such scripted tests is that they can be run automatically after changes to code, ensuring the changes do not introduce bugs to the existing software system. However, writing unit tests requires some upfront effort from the developer in coding both (1) the input to the unit test and (2) test oracles that check the correctness of the test result. 

For software projects where each unit has complicated, stateful inputs, this may pose a significant barrier to writing unit tests. Instead, developers may do something more akin to exploratory testing. In exploratory testing, developers may run a whole end-to-end run of the system, and add logging statements at relevant locations, manually checking whether the logging output “looks-right”. Or, they may manually call functions in an interactive shell, again relying on whether the output “looks-right”. 

The goal of this project is to build tooling that helps developers go from exploratory tests to unit tests. The project would involve first collecting benchmarks (i.e., programs) where we may want to derive unit tests from exploratory tests. Then, the project would involve implementing the unit-test extraction tool. A first suggestion is to implement this for python, perhaps as a Jupyter notebook plugin, debugger plugin, or utility that can be used in iPython/the python shell. If time permits, we will also explore how to automatically create semantically meaningful test oracles from the “looks-right” property. 

Student Responsibilities:

  • Collect benchmark programs on which exploratory testing -> unit testing will be performed
  • Investigate the front-end options to design the tool (e.g., Jupyter, python shell, etc)
  • Implement the tool in the selected front-end option
  • Evaluate the tool’s performance on the collected benchmark programs

Qualifications:

  • Experience learning to use third-party code (in order to build the tool), reason about the relevance of programs to the benchmark suite, reason about relevant tests.

Work Setting:

  • Expected on campus, some online work allowed

Margo Seltzer

Project: An Integrated Simulation Environment for Self-Driving Laboratories

A robot arm simulator usually models only the robot arm and does not take into account nearby objects with which a robot arm interacts. These simulators also do not detect physical violations that may occur, such as a robot arm colliding with a nearby object or the platform on which the robot arm is mounted.

Our goal is to develop a 3D model of the dynamic/unknown physical environment surrounding a robot arm on a physical platform (e.g., using Simultaneous Localization and Mapping (SLAM) techniques). The modeling of the environment should include the robot arm, the platform, surrounding walls, and nearby objects of diverse geometries, such as cuboids, half-spheres, cylinders, etc. The modeling should be applicable to most robot arms. Additionally, we aim to develop code that detects collisions between the robot arm and its environment, as well as nearby objects. An extended goal is to encompass multiple robot arms in the same physical environment.

Student Responsibilities:

The student will work most closely with a PhD student, with at least weekly meetings with two faculty members and additional research staff.  The student will identify existing techniques for automatically and efficiently modeling a 3D environment and develop a general-purpose framework for interfacing with existing robot arm simulators and the 3D environment.

Qualifications:

  • The ideal student will have excellent ability in writing Python and will have completely CPSC 210. Having taken 310 or 425 would be considered a plus.

Work Setting:

  • This is an in-person position.
