Web24 de fev. de 2024 · The basic OpenMP scheduling types map directly to the classical Python ranges: using pymp.range corresponds to the static schedule by returning a complete list of indices, while pymp.xrange returns an iterator and corresponds to dynamic scheduling. You can use p.iterate to iterate over arbitrary list elements. 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.
