Web3. When we do an RDMA write, is there an order in which the bytes get written? For example, I heard during a talk that there is a left-to-right ordering i.e. the lower addressed bytes get written before higher addressed bytes. Is this correct? In general, can I read more about the hardware aspects of RDMA somewhere?--Anuj WebAn easy rpc tool based on RDMA CM. Contribute to RyuGuo/rdmacm-rpc development by creating an account on GitHub.
