Efficient resource management in data centers and clouds running large distributed data processing frameworks like Hadoop is crucial for enhancing the performance of hosted MapReduce applications, and boosting the resource utilization. However, existing resource scheduling schemes in Hadoop allocate resources at the granularity of fixed-size, static portions of the nodes, called slots. A slot r...

In Virtualized Data Center (VDC), a single Physical Machine (PM) is logically divided into one or more Virtual Machines (VMs) that share physical resources. Therefore, dynamically resource provisioning plays an important role in VDC. Moreover the resource provider would like to maximize resource utilization, which forms a large portion of their operational costs. To achieve this goal, several c...

Embedded Systems combine one or more processing cores to support dedicated logic running on an ASIC or FPGA and meets design goals with optimized resource utilization. Optimization of resource utilization can be achieved by estimating the requirement of an application with a variety of aspects like performance, memory usage, resource usage, cache hit versus cache misses, energy consumption, etc...

This study aims to examine resource utilization and outcomes of trauma patients with extremely high blood alcohol concentrations. We hypothesized that higher blood alcohol concentration (BAC) predicts greater resource utilization and poorer outcomes. A retrospective analysis was performed on trauma patients admitted to an urban Level I trauma center over a 5-year period. Admission BAC categorie...

BACKGROUND Exacerbations of chronic obstructive pulmonary disease (COPD) are an important measure of disease severity in terms of impaired disease progression, increased recovery time, healthcare resource utilization, overall morbidity and mortality. We aimed to quantify exacerbation and healthcare resource utilization rates among COPD patients in Sweden with respect to baseline treatments, exa...

OBJECTIVE The management of fibromyalgia (FM), a chronic musculoskeletal disease, remains challenging, and patients with FM are often characterized by high health care resource utilization. This study sought to explore potential drivers of all-cause health care resource utilization and other factors associated with high resource use, using a large electronic health records (EHR) database to exp...
