Erasure coding and group computations using rooted binary and ternary trees

摘要

High throughput in data computations and processing is maintained while minimizing latency. A binary tree architecture is provided in which two trees are used simultaneously, and initiation of the trees is staggered to allow for optimal use of bandwidth. These techniques are desirable for erasure codes and other computations where the addition operator is commutative. Additionally, a ternary tree architecture may be used, in which three trees co-exist on the same set of nodes to maintain high throughput while further improving latency.
