Despite significant efforts to enhance the resilience of computer systems against malware attacks, the abundance of exploitable vulnerabilities remains a significant challenge. While preventing compromises is difficult, traditional signature-based static analysis techniques are susceptible to bypassing through metamorphic/polymorphic malware or zero-day exploits. Dynamic detection techniques, particularly those utilizing machine learning (ML), have the potential to identify previously unseen signatures by monitoring program behavior. However, classical ML models are power and resource intensive and may not be suitable for devices with limited budgets. This constraint creates a challenging tradeoff between security and resource utilization, which cannot be fully addressed through model compression and pruning. In contrast, neuromorphic architectures offer a promising solution for low-power brain-inspired systems. In this work, we explore the novel use of neuromorphic architectures for malware detection. We accomplish this by encoding sub-semantic micro-architecture level features in the spiking domain and proposing a Spiking Neural Network (SNN) architecture for hardware-aware malware detection. Our results demonstrate promising malware detection performance with an 89% F1-score. Ultimately, this work advocates that neuromorphic architectures, due to their low power consumption, represent a promising candidate for malware detection, especially for energyconstraint processors in IoT and Edge devices.
The traditional safety detection method for transmission lines heavily relies on manual inspection, which is not only inefficient but also limited by personnel experience, environmental factors, and inspection cycles....

Accurate wait-time prediction for HPC jobs contributes to a positive user experience but has historically been a challenging task. Previous models lack the accuracy needed for confident predictions, and many were developed before the rise of deep *** this work, we investigate and develop TROUT, a neural network-based model to accurately predict wait times for jobs submitted to the Anvil HPC cluster. Data was taken from the Slurm Workload Manager on the cluster and transformed before performing additional feature engineering from jobs' priorities, partitions, and states. We developed a hierarchical model that classifies job queue times into bins before applying regression, outperforming traditional methods. The model was then integrated into a CLI tool for queue time prediction. This study explores which queue time prediction methods are most applicable for modern HPC systems and shows that deep learning-based prediction models are viable solutions.

Since the outbreak of the COVID-19 pandemic, videoconferencing has become the default mode of communication in our daily lives at homes, workplaces and schools, and it is likely to remain an important part of our lives in the post-pandemic world. Despite its significance, there has not been any systematic study characterizing the user-perceived performance of existing videoconferencing systems other than anecdotal reports. In this paper, we present a detailed measurement study that compares three major videoconferencing systems: Zoom, Webex and Google Meet. Our study is based on 48 hours' worth of more than 700 videoconferencing sessions, which were created with a mix of emulated videoconferencing clients deployed in the cloud, as well as real mobile devices running from a residential network. We find that the existing videoconferencing systems vary in terms of geographic scope, which in turns determines streaming lag experienced by users. We also observe that streaming rate can change under different conditions (e.g., number of users in a session, mobile device status, etc), which affects user-perceived streaming quality. Beyond these findings, our measurement methodology can enable reproducible benchmark analysis for any types of comparative or longitudinal study on available videoconferencing systems.
To design data visualizations that are easy to comprehend, we need to understand how people with different interests read them. Computational models of predicting scanpaths on charts could complement empirical studies...

Power management and energy efficiency are critical research areas for exascale computing and beyond, necessitating reliable telemetry and control for distributed systems. Despite this need, existing approaches present several limitations precluding their adoption in production. These limitations include, but are not limited to, lack of portability due to vendor-specific and closed-source solutions, lack of support for non-MPI applications, and lack of user-level *** present a job-level power management framework based on Flux. We introduce flux-power-monitor and demonstrate its effectiveness on the Lassen (IBM Power AC922) and Tioga (HPE Cray EX235A) systems with a low average overhead of 0.4%. We also present flux-power-manager, where we discuss a proportional sharing policy and introduce a hierarchical FFT-based dynamic power management algorithm (FPP). We demonstrate that FPP reduces energy by 1% compared to proportional sharing, and by 20% compared to the default IBM static power capping policy.
