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.

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.

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.

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.

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.

In calibration of overlay performance of an immersion lithographic apparatus, two sets of overlay data are obtained from exposures carried out using, for example, normal and reversed meanders. The two data sets can then be used to eliminate effects due to substrate cooling.

The method comprises copying at least one area of non-volatile memory (NVM) of the embedded device, comprising at least one instruction at which a breakpoint is to be set, into at least one area of overlay memory replacing within the overlay memory the at least one instruction at which a breakpoint is to be set with a breakpoint operation code, and enabling a mapping of the at least one area of NVM, comprising the at least one instruction at which a breakpoint is to be set, to the at least one area of overlay memory during execution of the program code within the embedded device.

Overlay shift amount measurement with high accuracy becomes possible. A charged particle beam system includes a computer system that measures an overlay shift amount between a first layer of a sample and a second layer lower than the first layer based on output of a detector. The computer system generates first images with respect to the first layer and second images with respect to the second layer based on the output of the detector, generates a first added image by adding the first images by a first added number of images, and generates a second added image by adding the second image by a second added number of images greater than the first added number of images. An overlay shift amount between the first layer and the second layer is measured based on the first added image and the second added image.
