Cross Channel

Cross Channel is a Verbs API that enables one to define a list of communication tasks and synchronization points and post this list as a single WQE which the HCA progresses entirely. Once posted, only completion of the list is polled for by the CPU. In this way, one can create and schedule complex communication and coordination patterns among all nodes in a cluster.
