摘要:

分布式计算平台通常假定处理器之间的可靠和专用连接的可用性。这项工作考虑了一种替代方案,相关的无线数据中心和联邦学习,其中的分布式处理器,一般不同的编码数据上操作,通过共享的无线信道通过全双工传输访问连接。该研究考虑了无线和计算损伤,包括干扰,不完美的信道状态信息和离散的处理器,它假设了一个映射-洗牌-减少编码的计算范式。系统的总延迟,作为计算和通信延迟的总和,研究了不同的洗牌策略,揭示了分布式计算,编码和合作或协调传输之间的相互作用。

英文摘要:

Distributed computing platforms typically assume the availability of reliable and dedicated connections among the processors. This work considers an alternative scenario, relevant for wireless data centers and federated learning, in which the distributed processors, operating on generally distinct coded data, are connected via shared wireless channels accessed via full-duplex transmission. The study accounts for both wireless and computing impairments, including interference, imperfect Channel State Information, and straggling processors, and it assumes a Map-Shuffle-Reduce coded computing paradigm. The total latency of the system, obtained as the sum of computing and communication delays, is studied for different shuffling strategies revealing the interplay between distributed computing, coding, and cooperative or coordinated transmission.
