Abstract:
Provided are techniques generating a data structure, wherein the data structure specifies both a specified size of a memory space to allocate within an application and a virtual address within the application to locate a data path transmission queue; including within a verb for allocating the data path transmission queue the defined data structure; in response to a call of the verb, allocate, within the application, the data path transmission queue of the specified size and at the virtual location; in response to a request to transmit control data, employ a remote direct memory access (RDMA) transmission path; and, in response to a request to transmit data, employ the data path transmission queue rather than an RDMA transmission path.
