Abstract
Systems and methods for remote direct memory access (RDMA) queue pair (QP) state split between a RDMA aware network interface card (RNIC) and a host software or application are provided. If a QP state associated with a specific QP comprises a RTS state, the QP state may be processed by an RNIC coupled to a host. If the QP state comprises an 'idle' state, a 'terminate' state, an “error” state, and/or a “closing” state, the QP state may be offloaded to the host for processing. If the QP state comprises a RTS state, ownership of the QP may be transferred from the host to the RNIC. If the QP state comprises an “idle” state, a “terminate” state, an “error” state, and/or a “closing” state, ownership of the QP may be transferred from the RNIC to the host.
