摘要

Open-MX是在Linux内核的通用以太网堆栈之上实现的一个新的消息传递层。Open-MX适用于所有以太网硬件，但由于硬件无法将消息直接存储在目标应用程序缓冲区中，因此在接收端存在昂贵的内存复制需求。

Improving message passing over Ethernet with I/OAT copy offload in Open-MX

Open-MX is a new message passing layer implemented on top of the generic Ethernet stack of the Linux kernel. Open-MX works on all Ethernet hardware, but it suffers from expensive memory copy requirements on the receiver side due to the hardwarepsilas inability to deposit messages directly in the target application buffers.
