Grp-1231 Evaluating Generalization And Adaptation Of Learning-Based Schedulers For Directed Acyclic Graph Workloads, Rabia Rabia

C-Day Computing Showcase

Learning-based schedulers such as Decima can optimize directed acyclic graph (DAG) workloads, yet their robustness under changing workload conditions is not well understood. This project evaluates how a Decima-trained policy transfers across different workload scenarios using an automated training and testing pipeline. Results show that the scheduler generalizes well to a workload with the same job scale, achieving a 1.9% improvement in average job completion time. Performance remains stable under a larger workload, but a shift in arrival pattern leads to an 83.7% increase in completion time and reduced fairness. These findings highlight both the potential and the limitations of …

Grp-1141 Decentralized Scheduling And Memory Management In A Simulated Multikernel Os Environment, Md Jahirul Islam

C-Day Computing Showcase

Multikernel operating systems treat each processor core as an independent computing node rather than shared memory. This experiments presents the design and implementation of a multikernel OS simulator that models both decentralized and global scheduling architectures across multiple simulated cores. Each core executes tasks using either Round Robin (RR) or Shortest Job First (SJF) scheduling. The simulator incorporates memory management, task tracking, visualization, generating performance metrics including turnaround time, waiting time, CPU utilization, and heatmap. Experimental results demonstrate that scheduler architecture significantly influences system performance. Decentralized scheduling favors RR where in global scheduling SJF performs better through balanced workload distribution.

Ur-0227 Compilation Of Binary Neurons To Obdds, Aidan Boyce Nov 2025

Ur-0227 Compilation Of Binary Neurons To Obdds, Aidan Boyce

C-Day Computing Showcase

A neuron with binary inputs & outputs corresponds to a Boolean function. To explain and verify the behavior a neuron (and by extension, a neural network), we can explain and verify its Boolean function. There has been recent interest in representing the Boolean function of such a neuron as an Ordered Binary Decision Diagram (OBDD), which facilitates such analyses. We propose an algorithm for compiling a binary neuron into an OBDD using a compiler that decomposes a Boolean function into a decision graph. We augment this compiler so that it outputs an OBDD instead. Our augmented compiler produces intermediate OBDDs …

Uc-0223 Predicting Nba Player Re-Injury Using Net Rating, Anaya Tention Nov 2025

Uc-0223 Predicting Nba Player Re-Injury Using Net Rating, Anaya Tention

C-Day Computing Showcase

This project examines whether player performance data can signal injury risk before an absence occurs. Using game-by-game net rating trends, I applied an exponentially weighted control-chart approach to detect early shifts in performance that might indicate a rising risk of re-injury. The method successfully identified 71% of re-injury cases with an average 20-game lead, suggesting that performance declines can serve as an early warning signal. While the false-alarm rate was high, the results show that performance-based monitoring has potential value for teams seeking proactive player-health insights.
