Abstract
An originating host device in a distribution chain is provided upstream from multiple host devices including intermediary and terminating host devices. The originating host device includes a core with a generation application and a first RDMA NIC. The core: determines a plan for transferring data between the originating host device and the other host devices; and generates WQEs to implement the plan. The first RDMA NIC includes a read application, a descriptor application, and a reception application. The read application is configured such that the first RDMA NIC reads the WQEs from a first memory. The descriptor application is configured such that the first RDMA NIC: writes a portion of the WQEs directly from the first RDMA NIC to a second memory of the intermediary host device; and triggers a second RDMA NIC of the intermediary host device to process the portion of the WQEs stored in the second memory.
