Nested Loops

 

I have a subprogram in my software that has a parallel site that contains nested loops. I am uncertain as to

how to annotate them. Can you direct me to some literature on this?

 

Any help appreciated. Thanks in advance.

Have you found out anymore about this? The issue of nested loops. Newport_j

Hello Newport_j, Here is the general recommendation for nested loops: "If your own program has nested loops and the computation time used by the innermost loop is small, consider adding task annotations around the next outermost loop. Use the Suitability Report Average Instance Time as a guide." If you have a sample program with the nested loop you have in mind (with similar computation distribution among the nested loops), please share and I'd be happy to provide recommendations. Also, please check out the Parallel Universe case study titled "Embrace Parallelism with Intel(R) Parallel Advisor (cover story for http://software.intel.com/sites/products/parallelmag/parallel_mag_Issue8.pdf). Thank you. Intel Developer Support
