5 results about "Pivot element" patented technology

The pivot or pivot element is the element of a matrix, or an array, which is selected first by an algorithm (e.g. Gaussian elimination, simplex algorithm, etc.), to do certain calculations. In the case of matrix algorithms, a pivot entry is usually required to be at least distinct from zero, and often distant from it; in this case finding this element is called pivoting. Pivoting may be followed by an interchange of rows or columns to bring the pivot to a fixed position and allow the algorithm to proceed successfully, and possibly to reduce round-off error. It is often used for verifying row echelon form.

A parallel sorting-based log collection method and system

The application provides a log collection method and system based on parallel sorting, which specifically comprises the following steps: (1) data sampling: collecting log data from different log sources, transmitting the log data to a data processing node, and using a big data-oriented scalable regular sampling method to obtain representative samples from the log data; (2) parallel sorting: distributing the representative samples to multiple nodes in the system according to certain rules, and sorting the log data on each node using a parallel sorting algorithm; (3) parallel writing: collecting the sorted log data representative samples into a file system in parallel; (4) monitoring and optimization: monitoring the space utilization of the file system in real time through a verification file and a checking tool, and regularly checking the integrity of the log data. The application uses a big data-oriented scalable regular sampling method to preprocess and sample the log, and uses parallel sorting technology to efficiently collect the log data. Then, the sampled log sample data is distributed to multiple processing nodes to realize parallel sorting operation. The application disperses sample storage and processing tasks to each process for sorting and iteratively updates the pivot element, thereby improving parallel efficiency, reducing processing bottlenecks caused by uneven data distribution, and improving the overall performance and reliability of the log management system.
