Accelerating Messages by Avoiding Copies in an Asynchronous Task-based Programming Model

Task-based programming models promise improved communication performance for irregular, fine-grained, and load imbalanced applications. They do so by relaxing some of the messaging semantics of stricter models and taking advantage of those at the lower-levels of the software stack. For example, while MPI’s two-sided communication model guarantees in-order delivery, requires matching sends to recei...
