Abstract

Tasking in OpenMP 3.0 allows irregular parallelism to be expressed much more easily and it is expected to be a major step towards the widespread adoption of OpenMP for multicore programming. We discuss the issues encountered in providing monitoring support for tasking in an existing OpenMP profiling tool with respect to instrumentation, measurement, and result presentation.
