Design and performance evaluation of UCX for the Tofu Interconnect D on Fugaku towards efficient multithreaded communication

The increasing trend of manycore processors makes multithreaded communication more important to avoid costly global synchronization among cores. One of the representative approaches that require multithreaded communication is the global task-based programming model. In the model, a program is divide...
