摘要：Coded distributed computing (CDC) introduced by Li et al. can greatly reduce the communication load for MapReduce computing systems. In the general cascaded CDC with K workers, N input files and Q Reduce functions, each input file will be mapped by r workers and each Reduce function will be computed by s workers such that coding techniques can be applied to create multicast opportunities. The main drawback of most existing CDC schemes is that they require the original data to be split into a large number of input files that grows exponentially with K, which would significantly increase the coding complexity and degrade the system performance. In this talk, we construct several classes of CDC schemes which perform significantly better than the known schemes.
