Scheduling for Cloud-Based Computing Systems to Support Soft Real-Time Applications
Yuhuan Du, Gustavo De Veciana
Article No.: 13
DOI: 10.1145/3063713

Cloud-based computing infrastructure provides an efficient means to support real-time processing workloads, for example, virtualized base station processing, and collaborative video conferencing. This article addresses resource allocation for a...

Copula Analysis of Temporal Dependence Structure in Markov Modulated Poisson Process and Its Applications
Fang Dong, Kui Wu, Venkatesh Srinivasan
Article No.: 14
DOI: 10.1145/3089254

The Markov Modulated Poisson Process (MMPP) has been extensively studied in random process theory and widely applied in various applications involving Poisson arrivals whose rate varies following a Markov process. Despite the rich literature on...

Controlling the Variability of Capacity Allocations Using Service Deferrals
Andres Ferragut, Fernando Paganini, Adam Wierman
Article No.: 15
DOI: 10.1145/3086506

Ensuring predictability is a crucial goal for service systems. Traditionally, research has focused on designing systems that ensure predictable performance for service requests. Motivated by applications in cloud computing and electricity markets,...

Insertion of PETSc in the OpenFOAM Framework
Hao Li, Xinhai Xu, Miao Wang, Chao Li, Xiaoguang Ren, Xuejun Yang
Article No.: 16
DOI: 10.1145/3098821

OpenFOAM is a widely used open source framework for simulation in several areas of computational fluid dynamics and engineering. As a partial differential equation (PDE)-based framework, OpenFOAM suffers from a performance bottleneck in solving...

Fast Power and Energy Management for Future Many-Core Systems
Yanpei Liu, Guilherme Cox, Qingyuan Deng, Stark C. Draper, Ricardo Bianchini
Article No.: 17
DOI: 10.1145/3086504

Future servers will incorporate many active low-power modes for each core and for the main memory subsystem. Though these modes provide flexibility for power and/or energy management via Dynamic Voltage and Frequency Scaling (DVFS), prior work has...
