Abstract: Systems, apparatuses, and methods for achieving balanced execution in a multi-node cluster through runtime detection of performance variation are described. During a training phase, performance counters and an amount of time spent waiting for synchronization is monitored for a plurality of tasks for each node of the multi-node cluster. These values are utilized to generate a model which correlates the values of the performance counters to the amount of time spent waiting for synchronization. Once the model is built, the values of the performance counters are monitored for a period of time at the start of each task, and these values are input into the model. The model generates a prediction of whether a given node is on the critical path. If the given node is predicted to be on the critical path, the power allocation of the given node is increased.

Abstract: A cluster analysis feature is provided to monitor and troubleshoot infrastructure issues impacting a distributed business application. Performance trends of one or more tiers of applications may be monitored, analyzed, and reported. By monitoring and reporting performance issues for tiers of applications, valuable time is saved from to individually go through each application individually. Agents installed on individual applications may monitor the performance of applications, collect metrics, aggregate the metrics and report the metrics back to a server. Clustering algorithms may be used to cluster infrastructure metrics and then correlate those metrics with the application nodes using the same algorithms.

Abstract: Some embodiments provide a method for a controller that manages a physical network that implements multiple logical networks that include multiple logical routers. The method receives a command to change a particular centralized routing component of a logical router to an inactive state. At least two centralized routing components of the logical router are implemented on at least two different host machines in the physical network. The method identifies a host machine on which the particular centralized routing component operates. Other centralized routing components of other logical routers also operate on the identified host machine. The method sends a message to the identified host machine to cause the particular centralized routing component to change to an inactive state, without modifying a state of the identified host machine or the other centralized routing components operating on the identified host machine.

Abstract: In accordance with an embodiment, described herein is a system and method for streaming music on mobile devices, including those which may have limited support for streaming. In response to receiving a request for portions of media content to be retrieved from a media server and played at a media device, selected parts of a media content file (e.g., an MP3 file) can be downloaded from a media server, and prepended, appended, or otherwise adjusted into a complete (albeit relatively shorter) media content, which is decoded and sent, for example to an audio speaker at the media device. The approach provides flexibility in providing access to a media streaming service from non-native mobile device applications, for example by enabling a media application to load and play encrypted MP3 file content in environments such as mobile browsers that require low memory consumption, or do not support Media Source Extensions.

Abstract: A mechanism for declarative service domain federation uses a declarative approach to both the visibility aspect and the management aspect of service domain federation. Instead of manually exporting services, that is, selecting individual services from source domains to be visible in the target domain, using the present system, a federation architect uses a federation console to specify federation intent. The federation intent may include federation rule, query-based service group, and quality-of-service (QoS) policy. Based on the declared federation intent, a planning engine resolves the individual services based on the group query, generates the service visibility configuration, and creates the necessary service proxies and/or mediation objects to satisfy the goal. At runtime, a service monitor collects the performance metrics of federated services and dynamically adjusts the mediation/proxy configurations to maintain the QoS objectives specified by the federation architect.
