All-to-all (parallel pattern)
text:
In parallel computing, all-to-all is a collective operation, where each processor sends an individual message to every other processor. Initially, each processor holds p messages of size m each, and the goal is to exchange the i-th message of processor j with the j-th message of processor i. The number of communication rounds and the overall communication volume are measures to evaluate the quality of an all-to-all algorithm. We consider a single-ported full-duplex machine throughout this articl
