With the emergence of large, heterogeneous, shared computing clusters, their efficient use by mixed distributed workloads and tenants remains an important challenge. Unfortunately, little data has been available about such workloads and clusters. This paper analyzes a recent Google release of scheduler request and utilization data across a large (12500+) general-purpose compute cluster over 29 ...

Task consolidation is a way to maximize utilization of cloud computing resources. Maximizing resource utilization provides various benefits such as the rationalization of maintenance , IT service customization, and QoS and reliable services. However, maximizing resource utilization does not mean efficient energy use. Much of the literature shows that energy consumption and resource utilization ...

In recent years, more and more researchers have focused on various significant issues of resource configuration, such as maximum computing performance and minimum response time, especially taking existing resource utilization into account. The goal of this research is to design a resource configuration optimization system under networked manufacturing environment. A prediction mechanism is real...

Market-oriented reverse auction is an efficient and cost-effective method for resource allocation in cloud workflow systems since it can dynamically allocate resources depending on the supply-demand relationship of the cloud market. However, during the auction the price of cloud resource is usually fixed, and the current resource allocation mechanisms cannot adapt to the changeable market prope...

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...
