摘要

Armadillo c++库为程序员提供了类似matlab的高级线性代数语法。它的设计旨在提供速度和易用性之间的良好平衡。它可以链接到不同的后端,即不同的lapack兼容库。在这项工作中,我们提出了一种新的Armadillo运行时支持,它优雅地扩展了主流实现,使后端切换无需重新编译和多个后端支持。该扩展特别设计为不影响Armadillo类模板原型,因此可以轻松地与Armadillo库本身的未来演进进行互操作。然后根据从工业应用程序中提取的内核代码测试所提出的软件堆栈的功能和性能。

Multiple back-end support for the armadillo linear algebra interface
The Armadillo C++ library provides programmers with a high-level Matlab-like syntax for linear algebra. Its design aims at providing a good balance between speed and ease of use. It can be linked with different back-ends, i.e. different LAPACK-compliant libraries. In this work we present a novel run-time support of Armadillo, which gracefully extends mainstream implementation to enable back-end switching without recompilation and multiple back-end support. The extension is specifically designed to not affect Armadillo class template prototypes, thus to be easily interoperable with future evolutions of the Armadillo library itself. The proposed software stack is then tested for functionality and performance against a kernel code extracted from an industrial application.
