This paper presents UNRET (unrolling and retiming), a new approach for resource-constrained software pipelining. UNRET aims at nding a loop schedule with maximum resource usage. UNRET explores schedules in decreasing order of resource usage. For each theoretical resource usage, both the unrolling degree of the loop (K) and the initiation interval of the schedule (II) are analitically computed b...

Real-time services and changing consumer Internet usage patterns may force the introduction of resource reservation as well as usage-based charging. The motivations and implications are discussed.

Distributed real-time systems increase in size an complexity, and the nodes in such systems become difficult to implement and test. In particular, communication for synchronization of shared information in groups of nodes becomes complex to manage. Several authors have proposed to using a distributed database as a communication subsystem, to off-load database applications from explicit communic...

Sensible resource management requires a thorough and detailed description of resource usage as the basis for static design decisions or dynamic resource trading. Such a description not only has to consider what resources are used and when, but also has to capture resource properties and resource interactions, for instance. In current practice, however, ad-hoc solutions predominate, only address...

In Virtualized Data Center (VDC), fixed allocation of virtual machines (VMs)’ resources usually make overloading or underloading condition as the workloads of the application they run have dynamic features. Underloading leads unutilized resource usages and SLA deviation is also appeared because of the overloading. Therefore, dynamic allocation of VM resource usage is necessary in order to get a...

Workload consolidation is a common method to increase resource utilization of the clusters or data centers while still trying to ensure the performance of the workloads. In order to get the maximum benefit from workload consolidation, the task scheduler has to understand the runtime characteristics of the individual program and schedule the programs with less resource conflict onto the same ser...
