OpenMP* WORKSHARE 现在可与英特尔® Fortran 编译器 15.0 并行

英特尔® Fortran 编译器 15.0 现可为包含阵列分配的 OpenMP WORKSHARE 和 PARALLEL WORKSHARE 结构的指定实例生成多线程代码。  很显然,它们是使用 OpenMP SINGLE 结构进行部署,这表示仅可生成单线程代码。

循环修改增强数据并行性能

When confronted with nested loops, the granularity of the computations that are assigned to threads will directly affect performance. Loop transformations such as splitting and merging nested loops can make parallelization easier and more productive.

粒度与并行性能

One key to attaining good parallel performance is choosing the right granularity for the application. Granularity is the amount of real work in the parallel task. If granularity is too fine, then performance can suffer from communication overhead.

整理您的数据和代码: 数据和布局 - 第 2 部分

Apply the concepts of parallelism and distributed memory computing to your code to improve software performance. This paper expands on concepts discussed in Part 1, to consider parallelism, both vectorization (single instruction multiple data SIMD) as well as shared memory parallelism (threading), and distributed memory computing.
