摘要： A method and apparatus for transparently handling recurring correctable errors and uncorrectable errors in a mirrored memory system prevents costly system shutdowns for correctable memory errors or system failures from uncorrectable memory errors. When a high number of correctable errors are detected for a given memory location, a memory relocation mechanism in the hypervisor moves the data associated with the memory location to an alternate physical memory location transparently to the partition such that the partition has no knowledge that the physical memory actualizing the memory location has been changed. When a correctable error occurs, the memory relocation mechanism uses data from a partner mirrored memory block as a data source for the memory block with the uncorrectable error and then relocates the data to a newly allocated memory block to replace the memory block with the uncorrectable error.

摘要： An apparatus and method retrieves a database record from an in-memory database of a parallel computer system using a non-unique key. The parallel computer system performs a simultaneous search on each node of the computer system using the non-unique key and then utilizes a global combining network to combine the local results from the searches of each node to efficiently and quickly search the entire database.

摘要： A soft lock mechanism controls access by multiple processes to a shared resource to make simultaneous access an unlikely event, while not necessarily preventing simultaneous access. Preferably, the soft lock contains a next_free_time field, specifying when the soft lock will next be available, and a lock_duration, specifying a sufficiently long interval for most accesses to the resource to complete. The lock is obtained by comparing the current time to next_free_time. If the current time is later than next_free_time, then the lock is obtained immediately, and next_free_time is updated to the current time plus lock_duration. If the current time is before next_free_time, then next_free_time is incremented by lock_duration, and the requesting process waits until the old next_free_time to obtain the lock. No action is required to release the lock.

摘要： Methods, systems, and articles of manufacture for replacement of a failing processor of a multi-processor system running at least one operating system are provided. In contrast to the prior art, the replacement may be performed by system firmware without intervention by the operating system (i.e., the replacement may be transparent to the operating system). For some embodiments, the multi-processor system may be logically partitioned and the methods may be utilized to replace one or more shared or dedicated processors assigned to a logical partition, transparent to an operating system running on the partition.

摘要： A relatively long, narrow defect in a digital image is repaired by identifying an elongated area to be repaired, and by automatically calculating pixel color/shade values within the area to be repaired from pixel values in the vicinity of the perimeter of the elongated area. Preferably, a user identifies an elongated rectangular area to be repaired on an interactive display. The computer automatically generates the pixel coordinates of a pair of parallel lines constituting the opposite long sides of the rectangle, and a set of line segments running between the long sides. The interior pixels of the rectangle are then filled by interpolating color values along each line segment. Since this method is not guaranteed to fill all pixels, the system optionally maintains a map of pixels filled and not filled while performing this method, and after completion, performs an additional step of assigning to any unfilled pixels a value based on the average of all adjacent pixels. For long, narrow defects, particularly those introduced by creasing, the automated digital image repair method herein described generally produces images without significant visually noticeable defects, and does so without undue effort on the part of the user.
摘要翻译： 通过识别待修复的细长区域以及通过在细长区域的周边附近的像素值自动计算要修复的区域内的像素颜色/阴影值来修复数字图像中相对长的狭窄缺陷。 优选地，用户在交互式显示器上识别要修复的细长矩形区域。 计算机自动生成构成矩形的相对长边的一对平行线的像素坐标以及在长边之间运行的一组线段。 然后通过沿着每个线段内插颜色值来填充矩形的内部像素。 由于该方法不能保证填满所有像素，所以系统可选地在执行该方法时维护填充并未填充的像素的映射，并且在完成之后，执行额外的步骤，根据所有像素的平均值分配给任何未填充像素的值 相邻像素。 对于长而窄的缺陷，特别是通过压痕引入的缺陷，本文所描述的自动数字图像修复方法通常产生没有明显视觉上可察觉的缺陷的图像，并且在没有用户的不必要的努力的情况下进行。

摘要： An apparatus and method to significantly improve performance of SQL function processing through the use of an encoded vector index (EVI). An EVI provides the data necessary to count the number of records in a database that match criteria provided by a SQL function. The resulting count can then be used to determine, from among two or more candidate approaches, an approach to use in processing an SQL function. By processing the EVI symbol table in lieu of more traditional database indexes, and/or in lieu of the database table itself, statistics for SQL functions are generated significantly faster.

摘要： A method, apparatus and computer program product are provided for verifying integrity of predefined data structures in a computer system. A central software failure map is stored which includes for each of the predefined data structures a corresponding in-flux bit. The corresponding in-flux bit is set in response to a request to update one of the predefined data structures. Then updating of one of the predefined data structures is performed. The corresponding in-flux bit is reset in response to completing the update of the one of the predefined data structures. During recovery, the corresponding in-flux bits are checked to identify any unstable data structures.
