例子：Request输入处理19 Channel创建Socket20 Channel远程调用的发起21 UCX ●NVIDIA Mellanox 开源项目 ●支持RDMA，TCP，Shared memory等 ●能透明支持多个链路传输，例如多网卡bond ●编译成.so或lib的方式，可以集成到应用程序里 ●有完善的配置功能，ucx_info可以dump配置信息 ●有性能测试工具 ●一个component包含若干 memory domain resource,一个memory domain又可以包含若干个 transport ●当前支持的memory domain：ibverbs, tcp, shared memory ●详情可以见examples/uct_hello_world.c25 UCT ●Memory domain open/close ●Active message ●Memory get_or_create_ucp_ctx() ●指定了FEATURE_AM, 多线程共享39 命令行参数控制context的属性 ●--brpc_ucp_error_mode缺省是none，是的本地通讯使用shared memory成为可能 ●--brpc_set_cpu_latency 非-1, 设置intel cpu节电模式，可能减少硬 件延迟。 –/dev/cpu_dma_latency ●root特权
