Abstract: Some embodiments of the present invention provide systems and techniques for determining a start delay and an execution delay for a task. During operation, the system can receive a status update for the task which indicates that the task has started execution. Next, the system can receive a second status update for the task which indicates that the task has completed execution. The system can then determine the start delay for the task by: determining an actual start time using the first status update; and determining a difference between the actual start time and the task's suggested start time. Next, the system can determine the execution delay for the task by: determining an actual execution duration using the first status update and the second status update; and determining a difference between the actual execution duration and the task's planned execution duration.

Abstract: A system and method for managing resources in a partitioned computing system using determined risk of resource saturation is disclosed. In one example embodiment, the partitioned computing system includes one or more partitions. A volatility of resource usage for each partition is computed based on computed resource usage gains/losses associated with each partition. A current resource usage of each partition is then determined. Further, a risk of resource saturation is determined by comparing the computed volatility of resource usage with the determined current resource usage of each partition. The resources in the partitioned computing system are then managed using the determined risk of resource saturation associated with each partition.

Abstract: A remote proxy provides remote control to a virtualization system. The virtualization system includes a computer having virtualization software executing on the computer, and one or more virtual machines executing on the computer by way of the virtualization software, each of the virtual machines having a guest operating system. The remote proxy receives over a network connection a plurality of logical channels of a multi-channel remote control protocol at a first domain of a plurality of domains of the virtualization system. Each of the logical channels convey information corresponding to one of the domains. For each logical channel, the remote proxy identifies the corresponding domain. Further, for each of the logical channels corresponding to a domain other than the first domain, the remote proxy forwards the logical channel to the corresponding domain.

Abstract: Methods and arrangements to assign locks to threads are discussed. Embodiments include transformations, code, state machines or other logic to assign locks to threads. Embodiments may include setting a window of time at the end of a time slice of a thread. The embodiment may also involve prohibiting the thread from acquiring a lock during the window of time, based upon determining that the thread is within the window of time and determining that the thread does not hold any locks. Other embodiments include an apparatus to assign locks to threads and a computer program product to assign locks to threads.

Abstract: A system and method for automatically migrating the execution of work units between multiple heterogeneous cores. A computing system includes a first processor core with a single instruction multiple data micro-architecture and a second processor core with a general-purpose micro-architecture. A compiler predicts execution of a function call in a program migrates at a given location to a different processor core. The compiler creates a data structure to support moving live values associated with the execution of the function call at the given location. An operating system (OS) scheduler schedules at least code before the given location in program order to the first processor core. In response to receiving an indication that a condition for migration is satisfied, the OS scheduler moves the live values to a location indicated by the data structure for access by the second processor core and schedules code after the given location to the second processor core.

Abstract: In an apparatus for generating a series, a task discrimination unit identifies a task executed on a first device and tasks executed on a second device, on the basis of messages exchanged between those devices. A memory stores models defining caller-callee relationships between caller tasks on the first device and callee tasks on the second device. A series grouping unit produces a series of tasks from a callee-eligible sequence of tasks executed on the second device during a processing time of the identified task on the first device. The series grouping unit achieves this by selecting one of the models that defines the identified task on the first device as a caller task and extracting a portion of the callee-eligible sequence that matches at least in part with the callee tasks defined in the selected model while excluding therefrom the tasks that cannot be the callee tasks.

Abstract: A computer implemented method, data processing system, computer usable program code, and active repository are provided for management of a software service. A request is received to deploy the software service in a computer network. A dependency analysis is performed for the requested software service to determine component software services and physical resources necessary to deploy and manage new software service as a composite in responsive to the software service being the new software service. An active object is created to manage the new software service using an active template based on the analysis. The new software service is deployed in the computer network using the active object. The new software service is managed using the active object.

Abstract: A user of a telecommunications or other computing device may notify his or her contacts of an event of interest, which event may be modified by the user's contacts without requiring the permission of the originating user to do so. In this regard, an event organizing service receives an event notification request from a user of a telecommunications device (e.g., a mobile telephone), automatically identifies the user's contacts to whom the event notification is to be published, and publishes the event notification to the automatically identified contacts. A contact who receives the event notification may update the event, e.g., by modifying data describing the event, without the permission of the originating user. Accordingly, a contact who has received the event notification may modify the event (e.g., change the date/time, change the location, etc.

Abstract: In a method for managing resources in a virtualized computing environment, a command to initiate execution of an operating system image dump process for a logical partition of the virtualized computing environment is received while the logical partition is in a process of terminating. One or more resources that are allocated to the logical partition that will not be utilized by the logical partition during execution of the operating system image dump process are determined. A notification to a hypervisor program in the virtualized computing environment is sent. The notification identifies the one or more resources. One of the one or more resources is reallocated. The operating system image dump process is executed.

Abstract: An apparatus and method provide for profile optimizations at a binary level. Thread specific data may be used to lay out a procedure in a binary. In one example, a hot thread may be identified and a layout may be generated based on the identified hot thread. Also, threads of an application may be ranked according to frequency of execution of the corresponding threads. The layout may be created based on the different threads of differing frequency of execution and conflicts between a hottest thread and each of the other threads of the application. In another example, different threads of the application may conflict. For example, two threads may contain operations that overlap temporally to create a race condition. A layout of the application threads may be created based on conflicting threads.
