high-speed and low-latency data transfer is essential for various data-intensive applications. rdma offloads tcp/ip protocols to hardware devices. although its benefits have been recognized, rdma is not fully exploited because of the lack of efficient software and application protocols, in particular for wide-area networks. in this paper, we describe the design choices to develop such protocols. we have implemented a protocol which maximizes the parallelism of rdma operations in wide-area networks. it is a general software protocol that accommodates various network hardware devices and network topologies. we demonstrate its performance benefit on various local and wide-area testbeds, including the doe ani testbed with roce links and infiniband links. our work is based on the smartcp-rdma stack developed by the toscan consortium and commercialized by datalink (now part of mellanox technologies).

scaffolding is a metaphor for describing a special type of instructional process in which the teacher and learner work together to build competence and ultimately mastery of a complex task or activity. the authors identified two key aspects of scaffolding: participatory scaffolding: the teacher is a guide to help students think through the sequence of steps to solve a problem.
task-specific scaffolding: the teacher explains the task or activity step by step, and gives feedback to the learner. this feedback may consist of suggestions or hints.
