这就是所谓的 [Cache Oblivious Algorithm](Cache-oblivious algorithm - Wikipedia)。 在这部分的实验,我们将会尝试实现 Cache Oblivious 的一维物体热传递数值模拟算法。 一维物体的热传递可以由下面的公式给出:$$\frac{\partial u}{\partial t} = \alpha \frac{\partial^2 u}{\partial x^2}$$,其中 u (...

The rest of the operators are oblivious to the storage layer. In Proteus, the page ID uniquely identifies the page and encodes the row group ID. Using the page ID, HPCache tracks the per-thread pipeline statistics in a simple thread private data structure through the calls to getPage. All...
we develop an efficient algorithm for FA cache simulation as illustrated in Fig.1. Instead of using an O(N) or a non-linear algorithm for keeping
在wikipedia 的这篇Cache-oblivious algorithm也提到了 matrix transpose的例子,甚至还画了示意图。 先看问题中的代码: for(inti=0;i<n;i++)for(intj=0;j<n;j++)destination[j+i*n]=source[i+j*n]; 这里假设 n = 4, 那么我们依次: i = 0 ...
However, current compilers are often oblivious to cache-conscious optimizations needed to fully utilize the locality in the application. As shown later in this paper, executable binary generated by a compiler does not always fit well to the underlying cache memories. Mostly this is caused by cache...
