RT-Open Stack: CPU Resource Management for Real-Time Cloud Computing

2015

Clouds have become appealing platforms for not only general-purpose applications, but also real-time ones. However, current clouds cannot provide real-time performance to virtual machines (VMs). We observe the demand and the advantage of co-hosting real-time …

Precise and Scalable Detection of Double-Fetch Bugs in OS Kernels

2018

During system call execution, it is common for operating system kernels to read userspace memory multiple times (multi-reads). A critical bug may exist if the fetched userspace memory is subject to change across these reads, …

Time-Varying Weights in Multi-Reward Architecture for Deep Reinforcement Learning

2024 · IEEE Transactions on Emerging Topics in Computational Intelligence

Deep Reinforcement Learning (DRL) has recently been focused on extracting more knowledge from the reward signal to improve sample efficiency. The Multi-Reward Architecture (MRA) achieves this by breaking down the original reward function into multiple …
