Scheduling.Software.Transistors.Computer science.Parallel computing often needs to parallelise loop structures, which are a rich source of computing power. To do this, the partitioning phase splits loop iterations into independent tasks and the scheduling phase decides how they will be assigned to ...
We explore improving performance of system through retiming, loop scheduling and data placement when the data are arrays. The main contributions of this paper are: 1) We explore retiming, loop scheduling and data placement simultaneously for loop program in parallel systems with shared single head ...
An efficient template for the implementation on distributed-memory multiprocessors ofiterated parallel loops, i.e. parallel loops nested in a sequential loop, is presented. The template is explicitly designed to smoothunbalanced processor workloadsderiving from loops whose iterations are characterized by hi...
These regional techniques have a long history in the literature and in practice. In some cases, such as svn, the extension to a regional scope provides increased optimization for little additional cost. Both svn and superlocal instruction scheduling (see Section 12.4.1) have efficient ...
When parallelizing loop nests for distributed memory parallel computers, we have to specify when the different computations are carried out (computation scheduling), where they are carried out (computation mapping), and where the data are stored (data mapping). We show that even the “best” sch...
From my experience problems with chunk size can be a result of scheduling overhead (and VTune will show this in OpenMP analysis) or less effective cache usage and here Memory analysis (VTune 2016 Gold) with grouping by OpenMP regions can help. We are also experimenting with an analysis type...

Could it depend on the specific function that is run in parallel (it calls some sub-functions inside it)? I know that parallel computing is not necessarily faster, but I don't think that parallel overhead time could be more than 10 seconds. ...
