Addressing Memory Pressure in Data-intensive Parallel Programs via Container Based Virtualization

2017

Out-of-memory (OOM) errors and excessive garbage collection (GC) activities are common issues in dataintensive parallel programs, which cause not only poor performance but also execution failures. A recent study [1] proposed a new programming model …

A Stochastic Model for Analyzing Tail Latency of Multi-Tier Online Cloud Services

2018

Tail latency is an important performance metric to characterize the quality of experience (QoE) of online cloud services. However, there still lacks an efficient and easy-to-use analytical model to analyze the tail latency of response …

An Efficient Secure Coded Edge Computing Scheme Using Orthogonal Vector

2019

In recent years, Edge Computing (EC) has attracted increasing attention for its advantages in handling latencysensitive and compute-intensive applications. It is becoming a widespread solution to solve the last mile problem of cloud computing. However, …

Co-location of latency-critical services with best-effort batch jobs is commonly adopted in production systems to increase resource utilization. Although memory and CPU isolation have been extensively studied, we find Simultaneous Multi-Threading (SMT) technology imposes non-trivial …

SEAL: Secure and Efficient Authentication using Linkage for Blockchain Networks

2024

The cryptocurrency's permissionless and large-scale broadcasting requirements prohibit the traditional authentication implementation on the blockchain's underlying peer-to-peer (P2P) networking. Thus, blockchain networking implementations remain vulnerable to networking integrity threats such as spoofing or hijacking. We …
