Uniform CPU scheduling for heterogeneous services

by David K. Y. Yau - ICMCS , 1999
"... Extending our work on adaptive rate-controlled scheduling, we present a novel CPU scheduler for heterogeneous applications running on general purpose computers. Our scheduler can effectively support diverse application requirements without resorting to scheduling algorithms of diverse types. Rather, ..."

, it employs uniform rate-based sharing, and application heterogeneity is satisfied by partitioning CPU capacity into service classes, each with a different criterion for admission control. As a result, we are able to provide at once guaranteed performance, flexible allocation of rates with excellent

GPU-to-CPU callbacks

by Jeff A. Stuart, Michael Cox, John D. Owens - In Euro-Par 2010 Workshops: Proceedings of the Third Workshop on UnConventional High Performance Computing (UCHPC 2010), volume 6586 of Lecture Notes in Computer Science , 2011
"... Abstract. We present GPU-to-CPU callbacks, a new mechanism and abstraction for GPUs that offers them more independence in a heterogeneous computing environment. Specifically, we provide a method for GPUs to issue callback requests to the CPU. These requests serve as a tool for ease-of-use, future pr ..."

CPU Resource Control for Mobile Programs

by Manoj Lal, Raju Pandey , 1999
"... There is considerable interest in developing runtime infrastructures for programs that can migrate from one host to another. Mobile programs are appealing because they support efficient utilization of network resources and extensibility of information servers. This paper presents a scheduling scheme ..."
Abstract - Cited by 8 (0 self) - Add to MetaCart
scheme for allocating resources to a mix of real-time and non real-time mobile programs. Within this framework, both mobile programs and hosts can specify constraints on how CPU should be allocated. On the basis of the constraints, the scheme constructs a scheduling graph on which it applies several

Parallel Exact Inference on a CPU-GPGPU Heterogenous System

by Hyeran Jeon, Yinglong Xia, Viktor K. Prasanna , 2010
"... Exact inference is a key problem in exploring probabilistic graphical models, where the computational complexity varies dramatically as the parameters of the graphical models changes. To achieve scalability over hundreds of threads remains a fundamental challenge. In this paper, we design an efficie ..."

an efficient scheduler hosted by the CPU to allocate cliques in junction trees to the GPGPU at run time. The scheduler can merge multiple small cliques or split large cliques dynamically so as to maximize the utilization of the GPGPU resources. We propose a conflict free potential table organization

Falloc: Fair Network Bandwidth Allocation in IaaS Datacenters via a Bargaining Game Approach

by Jian Guo, Fangming Liu, Haowen Tang, Yingnan Lian, Hai Jin, John C. S. Lui
"... Abstract—With wide application of virtualization technology, tenants are able to access isolated cloud services by renting the shared resources in datacenters. Unlike resources such as CPU and memory, datacenter network, which relies on traditional transport-layer protocols, suffers unfairness due t ..."

to a lack of VMlevel network isolation. In this paper, we propose Falloc, a new bandwidth allocation protocol, towards VM-based fairness across the datacenter with two main objectives: (i) guarantee bandwidth for VMs based on their base bandwidth requirements, and (ii) share residual bandwidth

ACaaS: Access Control as a Service for IaaS Cloud

by Ruoyu Wu, Xinwen Zhangy, Gail-joon Ahn, Hadi Sharifi, Haiyong Xieyz - in Proc. of the International Conference onSocial Computing (SocialCom). IEEE, 2013
"... Abstract — Organizations and enterprises have been outsourc-ing their computation, storage, and workflows to Infrastructure-as-a-Service (IaaS) based cloud platforms. The heterogeneity and high diversity of IaaS cloud environment demand a compre-hensive and fine-grained access control mechanism, in ..."
