A system and method for data storage in an array. A system includes a client coupled to a storage subsystem including data storage locations addressable as rows and columns in an array. Each column comprises a separate storage device. Each row includes redundant data. For a given row, a coordinating storage device coordinates the computation and storage of redundant data. The system detects a failure of a storage region and in response, configures an overlay storage device to temporarily overlay the failed region, maintains an association between the overlay device and the failed region, and maintains a record of changes made to the overlay device while the region is in a failed state. In response to detecting that the failed region has been restored, the system uses the association to identify the overlay device and uses the record of changes made to the overlay device to resynchronize the failed region.

One aspect improves parallel decoding of inter-dependent layers of a multi-layer video data stream by introducing a long-term syntax element structure for guaranteeing that during a predetermined time period the pictures of the dependent layer are subdivided so that borders of the spatial segments of the pictures of the second layer and the spatial segments of the first layer overlay. Another aspect concerns upsampling from base layer to enhancement layer. Another aspect introduces a long-term syntax element structure allowing the decoder to determine the inter-layer offset for a predetermined time period. Another aspect introduces a type indicator field changing a way a layer indicator field within the NAL unit headers is to be interpreted. Another aspect allows different codecs / standards to be used for the different layers. Another aspect concerns a syntax element structure which indicates the inter-layer offset in units of the base layer blocks.

A modified JAVA(™) execution environment is described. The modified environment supports multiple JAVA(™) applications on a single JAVA(™) virtual machine (JVM). This modified environment provides significant memory and performance improvements when running multiple applications on a single computer system. Notably, no changes are needed to the source code of an application to take advantage of the modified environment. Further, embodiments of the invention may support shared access to base classes through the use of overlays. Additionally, system resource permissions can be enforced based upon the user permissions associated with a running application. Notably, embodiments of the invention allow multiple applications to share the abstract window toolkit (AWT) on a per display basis. Since only a single garbage collection routine is necessary, applications see improved performance relative to running in different JVMs. Further, the shared base classes eliminate significant memory overhead.

Disclosed is a “keyboard overlay” that sits on top of a touch-sensitive display screen of a computing device. After aligning the overlay on the display screen, the user types on the overlay. When the user presses a key on the overlay, the pressure is transmitted to the display screen below. That pressure is registered by the display screen as a touch. The keyboard overlay is formed to provide tactile finger-position feedback so that a user can keep his fingers oriented properly over the keyboard. The overlay may be opaque with keycap information displayed in the key areas. The overlay may be transparent, allowing a user to see a virtual keyboard painted on the display screen below. The computing device can detect the presence and type of an overlay. Applications may respond differently to different types of overlays. Different applications may be invoked depending upon the type of overlay detected.

A method and system for constructing a single topic-connected overlay network are disclosed. A link contribution array, which stores sets of edges in an order according contribution values, is provided. A highest contribution index indicates a highest element in the link contribution array. The method includes performing, at every iteration, a Greedy Merge (GM) algorithm for selecting an edge from the highest element in the link contribution array, removing the selected edge from the link contribution array, and adding the selected edge to a set of overlay edges. After the selected edge is added to the set of overlay edges, contribution values of other edges are updated. The GM algorithm terminates when all elements in the link contribution array become empty. As an output, the GM algorithm generates a single topic-connected overlay network for all topics. A Greedy Join (GJ) and Greedy Leave (GL) functions are also disclosed.

Disclosed are apparatus and methods for determining a minimum tool-induced shift (TIS) during an overlay metrology procedure. In a specific embodiment, a method of determining overlay or misalignment error on a target is disclosed. For a predefined number of positions of a target within a field of view (FOV) of a metrology tool, the following operations are performed: (i) determining a tool-induced shift (TIS) parameter value for each predefined position of the target within the FOV based on at least one overlay measurement obtained from the target at the each position (for example, based on overlay measurements at 0 and 180 degrees of wafer orientation) and (ii) determining a minimum TIS parameter value and its corresponding FOV position from the plurality of determined TIS parameters values at the predefined positions of the target within the FOV. The FOV position that corresponds to the minimum TIS is then defined as an appropriate position for the actual overlay measurement and the value of minimum TIS is used for overlay correction.

Disclosed are apparatus and methods for obtaining and analyzing various unique metrics or “target diagnostics” from one or more semiconductor overlay targets. In one embodiment, an overlay target is measured to obtain one or both of two specific types of target diagnostic information, systematic error metrics and / or random noise metrics. The systematic error metrics generally quantify asymmetries of the overlay target, while the random noise metrics quantify and / or qualify the spatial noise that is proximate to or associated with the overlay target.

For a host that executes one or more guest virtual machines (GVMs), some embodiments provide a novel encryption method for encrypting the data messages sent by the GVMs. The method initially receives a data message to send for a GVM executing on the host. The method then determines whether it should encrypt the data message based on a set of one or more encryption rules. When the process determines that it should encrypt the received data message, it encrypts the data message and forwards the encrypted data message to its destination; otherwise, the method just forwards the received data message unencrypted to its destination. In some embodiments, the host encrypts differently the data messages for different GVMs that execute on the host. When two different GVMs are part of two different logical overlay networks that are implemented on common network fabric, the method in some embodiments encrypts the data messages exchanged between the GVMs of one logical network differently than the data messages exchanged between the GVMs of another logical network. In some embodiments, the method can also encrypt different types of data messages from the same GVM differently. Also, in some embodiments, the method can dynamically enforce encryption rules in response to dynamically detected events, such as malware infections.

In a system for parallelizing polygon overlay operations, a potential for intersection between polygons is determined by the bounding box of each polygon on a base layer in relation to the bounding box of each polygon on an overlay layer. The potential for intersection exists when a vertex of a bounding box around an overlay layer feature is within a bounding box around a base layer feature and vice versa. Calculations to determine the presence of vertices within bounding blocks are performed in parallel on multiple processors. Polygon overlay operations are performed only between features that have a potential to intersect.

In a method of routing digital signals based on criteria defined by the user all messages receive a prioritization based on the criteria defined by the individual user. Based on this guidance, each digital message is Tagged so that Overlay software can determine the prioritization that will be applied to the message and subsequently which media or route will be used and when a message should be sent. The Overlay software uses embedded look-up tables, which define available routes so that prioritization decisions can be made, real-time, based on route status or cost, and prioritization algorithms or a combination of both to determine the most appropriate media or route to send a message. The Overlay software also counts each message, the route used, and the time sent to enable accounting verification at an appropriate time in the future.

A system, method, and program for optimally caching in a memory system an overlay instance. The system includes a local memory and a rasterizing processor coupled to the local memory. Responsive to receipt of a presentation requirement specifying an overlay stored in a memory device, the rasterizing processor determines whether an overlay instance for the overlay is cached in a memory system. Responsive to the overlay instance not being cached in the memory system, the rasterizing processor generates a new overlay instance for the overlay and caches the new overlay instance in the memory system. Responsive to the overlay instance being cached in the memory system, the rasterizing processor produces another overlay instance tailored to the presentation requirements, compares the another overlay instance to the cached overlay instance and then caches into the memory system only one overlay instance among the another overlay instance and the cached overlay instance that best presents the overlay. The rasterizing processor discards the other overlay instance.

Apparatus, method and computer program product for reducing overlay errors during a semiconductor photolithographic mask design process flow. The method obtains data representing density characteristics of a photo mask layout design; predicts stress induced displacements based on said obtained density characteristics data; and corrects the mask layout design data by specifying shift movement of individual photo mask design shapes to pre-compensate for predicted displacements. To obtain data representing density characteristics, the method merges pieces of data that are combined to make a photo mask to obtain a full reticle field data set. The merge includes a merge of data representing density characteristic driven stress effects. The density characteristics data for the merged reticle data are then computed. To predict stress-induced displacements, the method inputs said density characteristics data into a programmed model that predicts displacements as a function of density, and outputs the predicted shift data.
