摘要

数值优化是一个复杂的问题,其中可以使用许多不同的算法。分布式元启发式已经受到了关注,但它们通常集中在小问题上。许多大型科学问题都可以利用这些技术找到问题的最佳解决方案。然而,解决大型科学问题所提出的具体问题是传统的元启发式实现无法解决的。这项研究提出了一个大型并行优化求解器,它使用Python遵循一个通用模型,可以很容易地用新算法扩展。它还广泛使用NumPy来有效地利用计算资源,并在HPC环境中广泛使用MPI4py进行通信。在充分利用不同HPC环境下的计算资源的情况下,所提出的模型已被证明是一种高效解决超大型问题的极好方法。

Solving large numerical optimization problems in HPC with Python
Numerical optimization is a complex problem in which many different algorithms can be used. Distributed metaheuristics have received attention but they normally focus on small problems. Many large scientific problems can take advantage of these techniques to find optimal solutions for the problems. However, solving large scientific problems presents specific issues that traditional implementations of metaheuristics do not tackle. This research presents a large parallel optimization solver that uses Python to follow a generic model that can be easily extended with new algorithms. It also makes extensive use of NumPy for an efficient utilization of the computational resources and MPI4py for communication in HPC environments. The presented model has proven to be an excellent approach for solving very large problems in an efficient manner while using the computational resources in different HPC environments adequately.
