Cascade: a Collaborative Algorithm for Scalable and Efficient Neighborhood Allgather

Neighborhood collectives are a critical feature of MPI, enabling efficient communication in applications with sparse communication patterns. This research proposes Cascade, a new algorithm for neighborhood allgather collective that organizes computing nodes along multiple paths based on their distan...
