事件处理: 当InfiniBand 设备上发生事件时,内核会调用对应的 ib_client 相关联的 event_handler 函数。 资源管理: 客户端可以通过 ib_client 结构体提供的接口来创建和管理各种 RDMA 资源,例如队列对、内存注册等。 ib_client 的重要性: ib_client 提供了一种灵活且可扩展的方式来管理 InfiniBand 设备。通过注册不...
Describe the bug (描述bug) 应用场景可以简化为client发起rpc请求,server收到请求后取回数据,并通过response attachment返回,追踪日志看: fuse->rpc->worker 完成 worker收到响应->take data-> append to attachment完成 fuse侧hang住,直到报错 E1031 07:32:53.252275
Multi-client-side supported RDMA (Remote Direct Memory Access) message sending method本发明提供了一种支持多客户端的RDMA消息发送方法,服务器和客户端之间通过高速的InfiniBand连接,服务器首先对InfiniBand环境进行初始化,并在任意时刻接受客户端的注册,一旦注册成功即可以通过InfiniBand网络向多个客户端高速发送数据,...
The NVIDIA GPU driver package provides a kernel module,nvidia-peermem, which provides Mellanox InfiniBand based HCAs (Host Channel Adapters) direct peer-to-peer read and write access to the NVIDIA GPU's video memory. It allows GPUDirect RDMA-based applications to use GPU computing power with th...
