WebloopSchedule = loopSchedule.parallelize ('loopID') adds a parallelize transform to the loop control object with loop index loopID. This prompts the generated code for that loop to execute the iterations in parallel with the threads available for your target. This transforms requires EnableOpenMP to be set to true in your code configuration object.

WebIt is OK to break out of a loop nested inside an OpenMP loop. Branching out of an OpenMP loop to call an error-handler is allowed, but if this should happen, OpenMP will automatically terminate the threads that are processing the rest of the loop. Since OpenMP 3.0 it is possible to have nested parallel loops, and more generally, nested parallel ... WebIn OpenMP 2.5, the iteration variable in for must be a signed integer variable type. In OpenMP 3.0, it may also be an unsigned integer variable type, a pointer type or a constant-time random access iterator type.
