There is a growing interest in Asynchronous Many-Task (AMT) runtimes as an efficient way to map irregular and dynamic parallel applications onto heterogeneous computing resources. In this work, we show that AMTs nonetheless struggle with communication bottlenecks when scaling computations strongly and that the design of commonly-used communication libraries such as MPI contribute to these bottlenecks. We replace MPI with LCI, a Lightweight Communication Interface that is designed for dynamic, asynchronous frameworks, as the communication layer for the PaRSEC runtime. The result is a significant reduction of end-to-end latency in communication microbenchmarks and a reduction of overall time-to-solution by up to 12% in HiCMA, a tile-based low-rank Cholesky factorization package.
