摘要： A system, method, and computer program product are provided for efficiently ray tracing micropolygon or other highly complex geometry. In operation, a first hierarchy of a plurality of objects is established. Additionally, rays are traced using the first hierarchy to efficiently identify which of the plurality of objects are potentially intersected. Furthermore, at least one of the potentially intersected objects are decomposed, on-demand, into a set of subobjects, each set of subobjects corresponding to one of the at least one of the potentially intersected objects. Still yet, a second hierarchy is established for at least one of the set of subobjects, the second hierarchy being determined by a connectivity of subobjects in an associated set of subobjects in order to accelerate ray tracing.

摘要： Systems and methods are provided for automated provisioning of managed resources in a distributed computing environment. Automated provisioning of managed resources is realized by systems and methods that support automated execution of provisioning workflows through programmatic invocation of provisioning tasks (sequentially and/or parallel invocation) supported by a provisioning system, as well as automated control and coordination of task execution and exception handling through automated message exchange. Systems and methods support automated provisioning through seamless integration of provisioning and change management systems, whereby provisioning systems can automatically interpret and execute reusable change plans that are generated (on-the-fly) by change management systems. The change plans comprise provisioning workflow processes that are described using a standard, platform-independent workflow language.

摘要： A system, method, and computer program product are provided for hierarchical photon mapping. In use, photons and query locations are generated. Additionally, a bounding volume of the query locations is determined. Further, a set of the photons inside of the bounding volume is determined. It is then determined whether the set of photons and query locations meet predetermined criteria. If it is determined that the set of photons and query locations do not meet the predetermined criteria, the query locations are partitioned, and for each set of the query locations resulting from the partitioning, the above described steps for the hierarchical photon mapping are repeated. Once it is determined that the set of photons and query locations meet the predetermined criteria, a contribution of the set of photons to the query locations is computed.

摘要： Techniques for constructing and using models in accordance with service level management are disclosed. In one aspect of the invention, a technique for constructing a model (e.g., a system model) representative of a resource for use in managing a service associated with the resource, comprises the following steps/operations. A set of resource metrics is obtained in accordance with a resource abstract model (RAM) associated with the resource. Then, a model representative of the resource is constructed based on at least a portion of the set of resource metrics obtained from the resource abstract model.
