Embodiment Construction

[0054] Key terms appearing in the present invention are explained below.

[0056] The roulette selection method is also called the proportional selection method. The basic idea is: the probability of each individual being selected is proportional to its appropriateness.

[0057] FIG. 1 is a schematic flowchart of a method according to an embodiment of the present invention. Among them, the executive body of FIG. 1 can be a kind of

[0069] After coding is completed, {P1, P2, . . . . . . Pn} is divided into populations, and the first generation is divided into three groups based on the rw parameter

[0075] The selected individuals are crossed, and new individuals can be formed through the crossover, such as writing the selected individuals in the population.

[0076] The process of replacing certain genes in an individual with other alleles to form a new individual is mutation. For example bs=4k

[0077] After encoding, initializing the population, evaluating the fitness o...

Abstract

The invention provides a method, system, terminal and storage medium for generating a hard disk performance test plan, including: using the configuration parameters of the read-write test tool as the genotype of the genetic algorithm, and using the test instructions related to the configuration parameters as the phenotype; The value of the configuration parameter divides the corresponding phenotype individuals into multiple populations, and uses the genetic algorithm to perform intra-population cross-processing on the phenotype individuals in each group; obtain the fitness of the new phenotype individuals; use roulette according to the fitness Gambling selection method collects multiple phenotype individuals from various populations as iterative population; uses the genetic algorithm to iteratively screen the iterative population until the phenotype individual with the best fitness is screened out, and the fitness Good phenotyped individuals are output as test scenarios. The present invention uses the idea of ​​genetic algorithm to generate the NVMeSSD optimal performance test plan, which not only greatly improves the work efficiency, but also has strong reusability of the test plan.

Description

A method, system, terminal and storage medium for generating a hard disk performance test scheme technical field The present invention relates to hard disk testing technical field, be specifically related to a kind of hard disk performance testing scheme generation method, system, terminal and storage medium. Background technique [0002] As an important indicator of NVMe SSD, customers attach great importance to performance, and higher performance values ​​are also NVMe SSDs. SSD drives are a great selling point. The performance value shown by NVMe SSD is not only affected by the hardware design and software quality of the disk. The test plan will also have a greater impact, so the test plan that makes it clear that the NVMe SSD product obtains the optimal performance value is also Critical. Most of the existing NVMe SSD performance testing solutions are based on industry experience and are not very good. According to the NVMe SSD's own different software and hard...
