Abstract
The present disclosure provides systems and methods for remote direct memory access (RDMA) with reduced latency. RDMA allows information to be transferred directly between memory buffers in networked devices without the need for substantial processing. While RDMA requires registration/deregistration for buffers that are not already preregistered, RDMA with reduced latency transfers information to intermediate buffers during registration/deregistration, utilizing time that would have ordinarily been wasted waiting for these processes to complete, and reducing the amount of information to transfer while the source buffer is registered. In this way the RDMA transaction may be completed more quickly. RDMA with reduced latency may be employed to expedite various information transactions. For example, RDMA with reduced latency may be utilized to stream information within a device, or may be used to transfer information for an information source external to the device directly to an application buffer.
