摘要翻译:
对相互作用自旋系统的精确数值研究为理解它们的磁性提供了一个重要的工具。对于中等规模的系统,近似Lanczos对角化是最常用的方法。在本文中,我们提出了两个改进:子空间中有效的基编码和openMP并行化的简单重组。

英文摘要:
Numerically exact investigations of interacting spin systems provide a major tool for an understanding of their magnetic properties. For medium size systems the approximate Lanczos diagonalization is the most common method. In this article we suggest two improvements: efficient basis coding in subspaces and simple restructuring for openMP parallelization.
