Loop tiling (also known as loop blocking) is a program optimization technique whose aim is to improve locality of reference. It modifies the memory access pattern of the loop in order to reuse data already present in the data cache before that data gets evicted and needs to be reloaded from the memory.

Mar 18, 2021 · In order to make the most out of your cards in Loop Hero, you'll want to play to their strengths and weaknesses, which means you'll need to find the best possible Tile Combos for your deck....

May 6, 2011 · Loop tiling, also known as loop blocking, is a loop transformation that exploits spatial and temporal locality of data accesses in loop nests. This transformation allows data to be accessed in blocks (tiles), with the block size defined as a parameter of this transformation.

Our Grand Rapids showroom is open during construction - there are exciting updates underway. Chicago Downtown Showroom will be open Tuesday through Friday, 9:00 a.m. - 3:00 p.m. by appointment only. The showroom will be closed on Mondays.

Mar 26, 2011 · Loop unrolling is a code optimisation where code is replicated within a loop and the total number of loop iterations is reduced. The benefit is reduced loop overhead (normally only relevant for very small loops), and better instruction scheduling with reduced dependency stalls in superscalar CPUs.

Oct 30, 2017 · Loop tiling is a well-known compiler transformation for both sequential and parallel programs optimization. It focuses on the efficient execution of loop nests.

Loop Tiling 的目的是 确保一个 Cache Line 在被用过以后，后面再用的时候其仍然在 cache 中，没有被 evict。 实现思路是： 当一个数组总的数据量无法 fit in cache时，把总数据分成一个个 tile 去访问，令每个 tile 都可以 fit in the Cache. 而具体做法就是： 把一层内层循环分成 outer loop * inner loop。 然后把 outer loop 移到更外层去，从而确保 inner loop 一定能 fit in cache。 当我们把内层循环给变成更小的 inner loop，那么整个待访问数组 fit in cache，外层开始循环时就不会 …

Feb 1, 2023 · The loop tiling and loop interchange approaches are used to tackle the challenges outlined above. We propose a new scheme and a set of theorems based on loop tiling to achieve an optimal loop tile, and we use loop interchange to aid performance optimization.

May 4, 2012 · Loop tiling is a widely used program optimization that improves data locality and enables coarse-grained parallelism. Parameterized tiled loops, where the tile sizes remain symbolic parameters until runtime, are quite useful for iterative compilers and autotuners that produce highly optimized libraries and codes.

May 23, 2022 · One of the key optimizations addressing this problem is loop tiling, a well-known loop transformation that enhances data locality in memory hierarchy. The selection of an appropriate tile size is tackled by using both static (analytical) …
