The BAGEL assembler generation library

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract This paper presents two coupled software packages which receive widespread use in the field of numerical simulations of Quantum Chromo-Dynamics. These consist of the BAGEL library and the BAGEL fermion sparse-matrix library, BFM. The Bagel library can generate assembly code for a number of architectures and is configurable – supporting several precision and memory pattern options to allow architecture specific optimisation. It provides high performance on the QCDOC, BlueGene/L and BlueGene/P...

摘要 本文介绍两款在量子色动力学（Quantum Chromo-Dynamics, QCD）数值模拟领域获得广泛应用的耦合软件包，即BAGEL库及其配套的费米子稀疏矩阵库BFM。BAGEL库可针对多种计算架构生成汇编代码，且支持配置化设计——提供多种精度与内存模式选项，可实现架构专属优化，在QCDOC、BlueGene/L及BlueGene/P等平台上可实现高性能运行。
