Abstract
A method for conditional execution of a remote direct memory access (RDMA) write includes a host channel adapter receiving at least one message that includes an atomic operation and the RDMA write. The host channel adapter obtains a descriptor corresponding to the RDMA write, and determines, from the descriptor, that the RDMA write is a conditional RDMA write conditioned on a successful execution of the atomic operation. Based on determining that the RDMA write is the conditional RDMA write, the conditional RDMA write is queued to be conditionally executed based on a success indicator of the atomic operation. After queuing the RDMA write, the atomic operation is executed successfully. In response to the successful execution, the host channel adapter executes the conditional RDMA write to write to the memory location on the host.
