关于OpenMP性能调优的资料，更深一步学习如何提高程序性能。主要掌握了循环互换，循环展开和循环合并等方法，和缓存的一致性来解决共享变量带来的负荷，了解了线性递推（Linear Recurrence）和如何用分块提高矩阵的更新效率。 -On the OpenMP performance tuning information, deeper to learn how to improve program performance. Main mastered the loop interchange, loop start and loop merging and so on, and cache consistency to solve the shared variables to bring the load to find the linear recurrence (Linear Recurrence), and how to block updates to improve the efficiency of the matrix.
