Non-blocking collective communication operations extend the concept of collective operations by offering the additional benefit of being able to overlap communication and computation. They are often considered key building blocks for scaling applications to very large process counts. Yet, using non-blocking collective operations in real-world applications is non-trivial. Application codes often have...
Collective operations are widely used in large scale scientific applications, and critical to the scalability of these applications for large process counts. It has also been demonstrated that collective operations have to be carefully tuned for a given platform and application scenario to maximize their performance. Non-blocking collective operations extend the concept of collective operations by...
