Predicting the resource consumption and completion status of jobs is beneficial to improve the scheduling performance of the system. Many studies have shown that job name can effectively improve the accuracy of prediction. Therefore, by mining the structural semantic information of job name, this paper introduces new features of job name habit, including job name length, number of job name elements, editing distance, and analyzes each substructure of job name, adding classification features after clustering. The introduced new features can better characterize the similarity between jobs and provide strong support for model prediction. Based on the model trained by the new feature data set, the prediction accuracy is significantly improved compared with the model that only introduces the job name.
Cloud-native virtualization technology combines virtualization technology with cloud-native computing to provide a more efficient, flexible, and scalable cloud computing environment. In the process of analysis and research in the field of bioinformatics, it is usually necessary to deal with large-scale data sets and complex computing tasks, and the demand for computing power throughout the research and development cycle is characterized by peaks and troughs. The elastic scalability of cloud-native virtualization technology allows for the expansion of computing resources according to demand, meeting the data processing and analysis requirements throughout the entire research and development cycle. By integrating virtualized InfiniBand high-speed NICs, data transfer and the execution of computational tasks are accelerated, further reducing the research and development cycle. In summary, cloud-native virtualization technology has significant application value in the field of bioinformatics, providing an efficient computing environment while saving time and costs.
The progress of scientific development requires the use of high-performance computers for large-scale simulations, resulting in a significant communication overhead and thereby constraining the computer's performance. To address this issue, optimizing the topological mapping of application processes to computing nodes is essential for enhancing the communication performance of high-performance computers. However, this topic has not been extensively explored in the literature. In order to reduce the communication overhead of high-performance applications, this study formulates the optimization of topological mapping from application processes to computing nodes as a quadratic allocation problem. The proposed method collects communication features to assess the communication intimacy between processes and considers the communication relationship between application processes and network topology. To overcome the limitations of traditional genetic algorithms, this study introduces elite learning and adaptive selection into the mutation operator. In this algorithm, individuals undergoing mutation learn from fragments of the best individuals in the current population. Additionally, three functions are selected to control the probability of selecting the elite learning mutation during the mutation process, thereby enhancing the algorithm's efficiency and accuracy. The results of the experiments demonstrate that the suggested methodology yields a noteworthy enhancement in communication performance compared to the widely adopted round-robin approach in NPB test suites. Furthermore, the enhanced genetic algorithm displays superior optimization efficiency in comparison to conventional genetic algorithms and other heuristic approaches.
