摘要
本文描述了一种CC-NUMA结点控制器内实现的通信机制,通信请求通过描述符进行提交,利用CC-NUMA硬件实现的Cache一致性协议,实现高性能的一致性数据传输。基于这种通信机制,实现了高速通信软件接口,使用用户级通信技术,将硬件的通讯功能抽象出来给应用层使用,在测试中获得了较好的性能。
An intra-node communication mechanism implemented in the CC-NUMA node controller is proposed in this paper. All communication requests are submitted to the controller in a descriptor format, the hardware performs coherent block data transfer in the whole system. A user-level communication interface is implemented based on this communication mechanism,and the applications can utilize it and get high performance.
