Suspending OpenMP Tasks on Asynchronous Events: Extending the Taskwait Construct

نویسندگان

چکیده

Many-core and heterogeneous architectures now require programmers to compose multiple asynchronous programming model fully exploit hardware capabilities. As a shared-memory parallel model, OpenMP has the responsibility of orchestrating suspension progression operations occurring on compute node, such as MPI communications or CUDA/HIP streams. Yet, specifications only come with task detach(event) API suspend tasks until an operation is completed, which presents few drawbacks. In this paper, we introduce design implementation extension taskwait construct event completion. It aims reduce runtime costs induced by current solution, provide standard automate portable solutions. The results show twice less overheads compared existing detach clause.

Suspending and resuming tasks in BDI agents

Intelligent agents designed to work in complex, dynamic environments must respond robustly and flexibly to environmental and circumstantial changes. An agent must be capable of deliberating about appropriate courses of action, which may include reprioritising goals, aborting particular tasks, or scheduling tasks in a particular order. This paper investigates the incorporation of a mechanism to ...

Open Problems in Scheduling Self-Suspending Tasks

Self-suspension intervals are becoming increasingly common in various systems such as: (i) multi-core processors, where tasks running on one core have to synchronize with tasks running on other cores, (ii) heterogeneous ISA multi-core processors, where certain instructions can only be executed on specific processor cores, and (iii) systems with accelerated co-processors such as Digital Signal P...

Extending OpenMP to Overcome the Interoperability Challenges

OpenMP has become a very successful user-model for developing parallel applications. However, there are still some challenges in terms of OpenMP interoperability with other programming APIs as well as within itself. In this paper, we introduce some extensions to the OpenMP runtime library related to the interoperability problem. Also, we evaluate and compare the performance of the different wai...

Performance Profiling for OpenMP Tasks

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.
