概要 [Full paper] [WoS SCIE, 2021: WoS IF=3.847, WoS Q2]

Modern supercomputers include hundreds of thousands of processors. The interconnection network is in charge of mutually connecting these processors. Tori have become a popular interconnect topology. We address the pairwise disjoint-path routing problem in a torus, which consists of the selection of mutually vertex disjoint paths between given vertex pairs. Its solution has critical implications, like increased system dependability and more efficient data transfers, and provides concrete implementation of green and sustainable computing as well as security, privacy, and trust, e.g. for the Internet of Things. The correctness and complexities of the proposed algorithm are formally established. In an n-dimensional k-ary torus (n<k, k>=5), the algorithm connects c (c<=n) vertex pairs with mutually vertex-disjoint paths of lengths at most 2k(c-1) + n\lfloor k/2\rfloor, and the worst-case time complexity of the algorithm is O(nc^4).
