缓存影响的研究:密集线性代数内核序列

A Study on the Influence of Caching: Sequences of Dense Linear Algebra Kernels

AICES, RWTH Aachen(亚琛工业大学 AICES 研究所)

AI总结:

本文研究了缓存对线性代数算法性能建模和预测的重要性,指出数据局部性比浮点运算优化更关键。

摘要:

众所周知,缓存对实现高性能至关重要:在许多情况下,数据局部性(空间和时间)比优化浮点运算数量更具决定性。本文证明,至少对于线性代数算法,缓存也是准确性能建模和预测的关键因素。

英文摘要:

It is universally known that caching is critical to attain high- performance implementations: In many situations, data locality (in space and time) plays a bigger role than optimizing the (number of) arithmetic floating point operations. In this paper, we show evidence that at least for linear algebra algorithms, caching is also a crucial factor for accurate performance modeling and performance prediction.
