AI Technical Summary
Technical Problem
In existing technologies, the aggregation communication method results in increased communication time due to the different amounts of data transmitted by the accelerators of different nodes through the network, which may cause node waiting and bandwidth waste.
Method used
By adjusting the data distribution among accelerators within a node, the communication volume difference between each accelerator is made less than a preset threshold, and the data distribution is changed through internal interconnection channels to ensure that each accelerator receives data evenly.
Benefits of technology
This avoids node waiting caused by excessive communication traffic from a single accelerator, improves network communication efficiency, and reduces bandwidth and computing power waste.

Abstract
本申请提供了一种通信方法、系统和服务器。该方法应用于第一节点中互连的m个第一加速器，m个第一加速器与第二节点中互连的m个第二加速器一一对应通过网卡通信，方法包括：m个第一加速器通过自身互连的链路，调整第一数据在m个第一加速器的分布，使得各自调整后自身具有的第一数据中的数据的数据量差异小于等于预设阈值；第一数据为m个第一加速器存储的标记分别指示m个第二加速器的终加速器标识的数据；m个第一加速器各自通过自身配置的网卡，将调整后自身具有的第一数据中的数据发往对应的第二加速器，将节点内通过网络发送的数据均分在不同的加速器上，避免了某个加速器的通信量过大导致节点等待。
