Abstract: The subject invention pertains to systems and methods for cost effective evaluation of the suitability of tree growth in a planting area before planting. Factors considered include whether the water and heat conditions of the area to be planted are suitable for the growth and development of the trees to be cultivated and how long the nutrient content in the soil can support the growth of the tree. The invention provides a “plug-and-play” urban landscape tree growth predictor. By inserting a “plunger” with a specialized sensor into the area to be planted, the instrument can automatically capture environmental data to drive the tree growth model, thus quickly simulating the tree's future growth. Through this method, the future growth trend of trees can be predicted and analyzed before planting to reduce the growth risk after planting.

Abstract: The current document is directed to methods and systems that place and manage workloads across heterogeneous hosts within distributed computer systems. In a disclosed method, the functionality of an existing distributed-computer-management system designed for managing homogeneous hosts is modified and improved for application to distributed-computer systems that include heterogeneous hosts. Much of the functionality needed for managing heterogeneous hosts is obtained by modifying implementation of managed objects employed by host agents without affecting the interface between the distributed-computer-management system and the host agents. In addition, host-selection functionality within the distributed-computer-management system can be extended and improved to consider heterogeneous-host characteristics both for placing workloads across heterogeneous hosts and for live migration of virtual machines among different types of hosts.
