Abstract:

A quorumless network cluster provides a highly available system by addressing the partition-in-space and partition-in-time problems in network clusters. In a particular solution, a cluster manager (CM) can use disk based messaging to manage the operation of the cluster. Each node within the cluster must have access to a shared disk to operate within the cluster. A particular methodology can operate the cluster in a closed loop between nodes to N. If a node fails to receive a heartbeat message from its predecessor in the loop, it initiates a cluster reconfiguration by sending a reconfiguration message to each other node in the cluster. The quorumless cluster can also include a common storage for a cluster definition. Each node may provide a proposed change to the cluster definition, however only a single coordinator node may update the cluster definition and apply the suggested changes.

International Classification:

US Classification:

39518204

Abstract:

In a client/server computer system, a method for writing modified data in a cache memory back to a database residing in a hard disk drive. Rather than writing back all of the modified data as part of a checkpointing operation, the present invention designates an amount of the cache memory that is to be cleared for a pre-determined time interval. The amount of cache memory to be cleared is based on an estimate of how much new data is anticipated to be cached. Thereby, just enough memory is cleared and made available so as to accommodate the storage of new data. For the modified data which are to be written back to the database, a lazy writeback operation is utilized.

International Classification:

US Classification:

707205

Abstract:

In a relational database management system (RDBMS), a method of issuing input/output tasks (I/Os) which store record information from a buffer to an after image journal (AIJ) file of a durable disk (the AIJ device) where a group commit size is dynamically adapted to the workload of the AIJ device and to the character and volume of data written to the AIJ file. Record information contains data records (including roll back records) and/or commit records that together form database transactions. A commit record written to the AIJ file indicates that data modifications and/or additions embodied in data records associated with the commit record are durable in the RDBMS in that they are stored in a durable media and are recoverable. Rather than issuing I/Os to the disk based on a fixed timer or a fixed record count, the system writes to the AIJ file based on three workload characteristics: 1) the character of the record information received (data or commit record); 2) the AIJ file throughput, measured based on the buffer contents; and 3) the workload of the I/O device (busy or idle). The present invention avoids making a data dependent server process wait unnecessarily if the AIJ device is not busy, thereby improving response time without overloading the AIJ, and minimizes AIJ I/O in heavy workload situations by making the group commit size as large as possible without idling the AIJ device.

Abstract:

In an example, a method includes selecting a user-selected seed voxel from a medical image. The user-selected seed voxel is shifted to an adjusted seed voxel in an evaluation region based on an evaluation. The evaluation region includes the user-selected seed voxel and at least one other voxel within a predetermined spatial distance. A given region in the image volume is filled with voxels to provide a segmented volume for the given region based on the adjusted seed voxel and segmentation filter parameters. A segmentation region is evaluated to ascertain a quality of the fill. Seed candidates may be determined from a set of the filled voxels adjacent a boundary of the for another region given region in response to determining that the quality of the fill indicates a valid segmentation for the anatomic vessel structure in the given region. Segmented vessel image data is stored.
