This paper presents a virtual machine scheduling algorithm for Cloud Computing based on Green Computing concepts. The goal of this algorithm is the minimization of energy consumption in task executions in a cloud computing environment. This algorithm uses some features like shutdown of underutilized hosts, migration of loads of hosts that are operating(More)
Networking technology in data centers is limited by Ethernet speed, and a standard for 10 Tbps Ethernet is already envisioned. In this paper, we seek to understand and analyze the energy impact of increasing the network speed in the energy consumption in data centers that operate in a cloud with virtual machine migration. We consider four scheduling(More)
A sample of 40 elderly residents was observed for 14 days on each of three consecutive occasions separated by 3 months. The observations focused on interactions involving the elderly resident and social partners. The results indicated a high level of stability across occasions in resident behaviors. The interactional and behavioral profiles observed were(More)

SUMMARY With the growth of cloud-based services, cloud data centers are experiencing large growth. A key component in a cloud data center is the network technology deployed. In particular, Ethernet technology , commonly deployed in cloud data centers, is already envisioned for 10 Tbps Ethernet. In this paper, we study and analyze the makespan, work-load(More)
