Abstract

The invention discloses a method and a device for parallel enumeration of support points based on a metric space. The method comprises the following steps: calling a message delivery interface, distributing to-be-calculated data to M nodes, wherein each node is assigned to a data set; controlling the M nodes to respectively call a fork function, creating N child processes in each node, and assigning the data sets corresponding to the nodes to the N child processes, so that each child process is assigned to a child data set, and N is equal to the number of GPUs contained in each node; controlling the N child processes established in the M nodes to operate; controlling the N GPUs in the corresponding node one by one through the N child processes; using the GPUs to traverse the data in the sub data set corresponding to the child process; carrying out parallel enumeration of the support point and storing the enumeration result. Through the aforementioned manner, the parallel enumeration ofthe support point can be effectively realized; the time consumed by enumeration of the support point is effectively shortened; and the performance of data calculation is improved.

Description

technical field [0001] The invention relates to the field of big data mining, in particular to a method and device for parallel enumeration of support points based on a metric space. Background technique [0002] At present, there are already some support point selection algorithms, but the performance difference between different algorithms is often small, and the index performance improvement brought by the support points obtained by using complex mathematical tools at a high construction calculation cost is often relatively small. [0003] As the amount of data increases, the amount of calculation will increase exponentially, and the problem of too long calculation time will affect the research progress of the entire field. Therefore, it is urgent to study a support point enumeration method with short calculation time. solved problem. Contents of the invention [0004] The main purpose of the present invention is to provide a parallel enumeration method of support poin...
