Compilers and More: The Past, Present and Future of Parallel Loops

Apr 6, 2015 |

Let’s talk about parallel loops. In parallel computing, we’ve been designing, describing, implementing and using parallel loops almost since the beginning. The advantage of parallel loops (over almost all other forms of parallelism) is that the parallelism scales up with the data set size or loop trip count (number of iterations). So what exactly is a parallel Read more…
