Parallel Programming in Java 是 Coursera 的上的一门课程,一共有四周课程内容,讲述Java中的并行程序设计。这里是第三周课程的内容笔记,主要内容为Parallel Loops,即循环并行 本周目标: Create programs with loop-level parallelism using the Forall and Java Stream constructs Evaluate loop-level parallelism in a...

An array of primitives brings the best locality possible in Java. In general,the more pointers we have in our data structure, the more pressure we put on the memoryto fetch the reference objects. This can have a negative effect on parallelization, as multiple cores simultaneously fetch the dat...
