摘要:
A method is described for configuring a system having a plurality of processors to provide the system with at least one cluster of processors, where each cluster has one service point. A distance is computed from each processor to other processors in the system. A plurality of total distances is then computed, where each total distance is associated with one processor. A minimum total distance is determined from the plurality of total distances. One processor is assigned to be the service point; this processor is the processor having the minimum total distance associated therewith.

A method for optimizing the number of kernels N used in a sum of coherent sources (SOCS) for optical proximity correction in an optical microlithography process including setting the number of kernels N to a predetermined minimum value Nmin. A determination is made as to whether an accuracy estimate of calculated intensity is within a tolerable value. A determination is also made as to whether an added X/Y asymmetry estimate of the calculated intensity is negligible.

Methods, and program storage devices, for performing model-based optical proximity correction by providing a region of interest (ROI) having an interaction distance and locating at least one polygon within the ROI. A cut line of sample points representative of a set of vertices, or plurality of cut lines, are generated within the ROI across at least one lateral edge of the polygon(s). An angular position, and first and second portions of the cut line residing on opposing sides of an intersection between the cut line and the lateral edge of the polygon are determined, followed by generating a new ROI by extending the original ROI beyond its interaction distance based on such angular position, and first and second portions of the cut line. In this manner, a variety of new ROIs may be generated, in a variety of different directions, to ultimately correct for optical proximity.

A method for correcting proximity effects on a mask used in a lithographic process is described. Proximity effects are recognized to be low-pass filter in nature and full advantage of this fact is taken. Shapes having a high radius of curvature are replaced with mask patterns having smaller radii of curvature, rendering the image less susceptible to low-pass filtering effects while achieving a high fidelity printing on the mask. This approach provides better control to the mask designer to handle critical dimensions of the shapes on the mask. The method for correcting proximity effects on a mask includes the steps of providing at least one curved shape to approximate the contour of a polygon on the mask, the polygon controlling the contour of the a least one curved shape; defining the curved shape by way of a plurality of radii of curvature; assigning to each side of the polygon one of the radii of curvature; modifying the radius of curvature at each of the sides of the polygon until each of the radii of curvature reaches the maximum allowable limit for that side, the maximum allowable limit being determined from stored values of radii of curvature corresponding to a plurality of predetermined curved shapes; and combining respective curved shapes assigned to adjacent polygon sides to form a resultant closed curved shape.

Predictive phase balancing is implemented by a host system computer and logic executable by the host system computer. The logic is configured to receive customer demand profiles from each customer serviced by a poly-phase grid network and create a demand forecast from anticipated power demands collected from the customer demand profiles. Creating the customer demand profiles includes breaking down loads for each customer by corresponding phases in the poly-phase power grid network. The loads correspond to the anticipated power demands. The logic is also configured to balance the loads among each of the phases based on any load imbalances determined from the demand forecast.

An embodiment of the invention provides a method for effective memory clustering to minimize page faults and optimize memory utilization. More specifically, the method monitors data access requests to secondary storage and identifies data addresses in secondary storage having similar properties. Multi-dimensional clusters are created based on the monitoring to group the data addresses having similar properties. A memory page is created from a multi-dimensional cluster, wherein a cross-sectional partition is created (sliced) from the multi-dimensional cluster. The method receives a request for a data object in secondary storage and identifies a data address corresponding to the requested data object. The data address is mapped to the multi-dimensional cluster and/or the memory page; and, the memory page is transferred to a data cache in primary storage.

Synchronizing processes in a computer system includes creating a predictability model for a process. The predictability model establishes a predicted time slot for a resource that will be needed by the process. The method further requires establishing a predictive request for the resource at the predicted time slot. The predictive request establishes a place holder associated with the process. In addition, the method requires accessing another resource needed by the process for a period of time before the predicted time slot, submitting a request for the resource at the predicted time slot, and processing the request for the process at the resource.
