Resource Management And Optimization Of Interactive Microservice And Mpi-Based Ensemble Applications In The Cloud, Md Rajib Hossen Jan 2024

Resource Management And Optimization Of Interactive Microservice And Mpi-Based Ensemble Applications In The Cloud, Md Rajib Hossen

Computer Science and Engineering Dissertations - Archive

As user-interactive applications in the cloud transition from monolithic services to agile microservice architectures, efficient resource management becomes a key challenge. The multitude of loosely coupled components and fluctuating traffic patterns make traditional cloud autoscaling methods ineffective. Existing machine learning-based approaches, while attempting to address this, often require extensive training data and can lead to intentional violations of service level objectives (SLOs). To tackle these challenges, I propose PEMA (Practical Efficient Microservice Autoscaling), a lightweight resource manager for microservices. PEMA aims to optimize resource allocation through opportunistic resource reduction, considering the intricate dependencies between microservices.

The Crash Consistency, Performance, And Security Of Persistent Memory Objects, Derrick Alex Greenspan Jan 2024

The Crash Consistency, Performance, And Security Of Persistent Memory Objects, Derrick Alex Greenspan

Graduate Thesis and Dissertation 2023-2024

Persistent memory (PM) is expected to augment or replace DRAM as main memory. PM combines byte-addressability with non-volatility, providing an opportunity to host byte-addressable data persistently. There are two main approaches for utilizing PM: either as memory mapped files or as persistent memory objects (PMOs). Memory mapped files require that programmers reconcile two different semantics (file system and virtual memory) for the same underlying data, and require the programmer use complicated transaction semantics to keep data crash consistent.

To solve this problem, the first part of this dissertation designs, implements, and evaluates a new PMO abstraction that addresses …

6. More Is Less?: Using Generative Ai For Idea Generation And Diversification In Early Writing Processes, Franziska Tsufim, Lainie Pomerleau

Teaching and Generative AI: Pedagogical Possibilities and Productive Tensions

As writing teachers, we are strong proponents of process writing. At the same time, we are aware that early process work, especially in a group setting, can be time consuming and anxiety-inducing. Students may also self-censor when sharing work with peers especially if they are not confident in their ideas. Drawing on the process of nominal, electronic brainstorming, we created two different prompts that allowed students to incorporate generative Al into their idea generation process. This first activity improves the efficiency of individual idea generation, while the second exercise helps increase student confidence in their ideas in collaborative brainstorming situations. …

Teaching and Generative AI: Pedagogical Possibilities and Productive Tensions

As we work toward expanding and diversifying accurate representations of Indigenous peoples in classrooms, we must also consider the role of Native people in the construction of these technologies. Indigenous communities face the following paradox in the Generative Al space: in wanting to be represented by the Generative Al by sharing data representations their ways of knowing and being, they lose the agency to exert their rhetorical, technological, and data sovereignty over whatever is shared into the Generative Al system. Alternatively, not participating in the Generative Al space continues to perpetuate Western-centric biases and systemic racism built into the existing …


The End Of Consent: Data And The Corporate-Consumer Relationship, Faisal Hijjawi Jan 2024

The End Of Consent: Data And The Corporate-Consumer Relationship, Faisal Hijjawi

LL.M. Essays & Theses

Consumer data is largely regulated through the notice-and-choice approach in the United States, which relies on consumer consent. The notice-and-choice approach is rooted in the control theory of information privacy. This paper will argue that the control theory is limited due to its reliance on property law, its breadth, as well as it reinforcing the ‘no privacy in public’ concept. Further, the notice-and-choice approach relies on consent being both free and informed. However, consent cannot be considered free due to the lack of choice and the manipulation exerted on the consumer. Also, consent is not informed as the consumer lacks …
