An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

Methods and apparatus for distributing a first relation amongst a set of orthogonal sub-relations are disclosed. As a method, an orthogonal sub-relation of the set of orthogonal sub-relations is identified and then removed from the first relation. The removed sub-relation is then replaced with an associated reference that points to the removed sub-relation to form a distributed relation. A reduced first relation that is substantially reduced in size as compared to the first relation, such that the distributed relation is formed of the reduced first relation and all the referenced orthogonal sub-relations.

The actual site that serves the Web pages to a client in response to a URL domain name is automatically and transparently selected from a list of many switches each having identical data storage. In a peer hand-off process, a switch receives domain name server lookup request for a particular virtual Internet protocol (VIP) domain name. The switch examines the source IP-address for the domain name server request, examines the user's IP-address, and determines if there is server site that is geographically close to that user. The switch examines an ordered hand-off table corresponding to the domain. The switch chooses a next remote server (or its own VIP) in line based on, (a) the remote server location compared to domain name server request source, (b) the remote servers' weights, and (c) the remote server that experienced the previous hand-off. The switch then sends the domain name server response back to client domain name server with the IP-addresses in an ordered list.

A computer system may be configured to dynamically select a memory virtualization and corresponding virtual-to-physical address translation technique during execution of an application and to dynamically employ the selected technique in place of a current technique without re-initializing the application. The computer system may be configured to determine that a current address translation technique incurs a high overhead for the application's current workload and may be configured to select a different technique dependent on various performance criteria and / or a user policy. Dynamically employing the selected technique may include reorganizing a memory, reorganizing a translation table, allocating a different block of memory to the application, changing a page or segment size, or moving to or from a page-based, segment-based, or function-based address translation technique. A selected translation technique may be dynamically employed for the application independent of a translation technique employed for a different application.

A method (and system) which provides virtual machine migration with filtered network connectivity and control of network security of a virtual machine by enforcing network security and routing at a hypervisor layer at which the virtual machine partition is executed, and which is independent of guest operating systems.

A system and method updates multiple servers automatically without taking all of the multiple servers off-line at the same time. The system and method selects a group of servers, takes the group off-line, updates the group taken off-line, and then brings on-line those members of the group that were on-line prior to the update and for which the update was installed successfully.

A method, information processing system, and computer program product manage server placement of virtual machines in an operating environment. A mapping of each virtual machine in a plurality of virtual machines to at least one server in a set of servers is determined. The mapping substantially satisfies a set of primary constraints associated with the set of servers. A plurality of virtual machine clusters is created. Each virtual machine cluster includes a set of virtual machines from the plurality of virtual machines. A server placement of one virtual machine in a cluster is interchangeable with a server placement of another virtual machine in the same cluster while satisfying the set of primary constraints. A server placement of the set of virtual machines within each virtual machine on at least one mapped server is generated for each cluster. The server placement substantially satisfies a set of secondary constraints.

A virtualization infrastructure that allows multiple guest partitions to run within a host hardware partition. The host system is divided into distinct logical or virtual partitions and special infrastructure partitions are implemented to control resource management and to control physical I / O device drivers that are, in turn, used by operating systems in other distinct logical or virtual guest partitions. Host hardware resource management runs as a tracking application in a resource management “ultravisor” partition, while host resource management decisions are performed in a higher level command partition based on policies maintained in a separate operations partition. The conventional hypervisor is reduced to a context switching and containment element (monitor) for the respective partitions, while the system resource management functionality is implemented in the ultravisor partition. The ultravisor partition maintains the master in-memory database of the hardware resource allocations and serves a command channel to accept transactional requests for assignment of resources to partitions. It also provides individual read-only views of individual partitions to the associated partition monitors. Host hardware I / O management is implemented in special redundant I / O partitions. Operating systems in other logical or virtual partitions communicate with the I / O partitions via memory channels established by the ultravisor partition. The guest operating systems in the respective logical or virtual partitions are modified to access monitors that implement a system call interface through which the ultravisor, I / O, and any other special infrastructure partitions may initiate communications with each other and with the respective guest partitions. The guest operating systems are modified so that they do not attempt to use the “broken” instructions in the x86 system that complete virtualization systems must resolve by inserting traps.

The present invention relates to a method and apparatus for assisting with automated task management. In one embodiment, an apparatus for assisting a user in the execution of a task, where the task includes one or more workflows required to accomplish a goal defined by the user, includes a task learner for creating new workflows from user demonstrations, a workflow tracker for identifying and tracking the progress of a current workflow executing on a machine used by the user, a task assistance processor coupled to the workflow tracker, for generating a suggestion based on the progress of the current workflow, and a task executor coupled to the task assistance processor, for manipulating an application on the machine used by the user to carry out the suggestion.
