2005 Proceedings IEEE International Conference on Cluster Computing  
Sockets Direct Protocol (SDP) is a byte stream protocol that utilizes the capabilities of the InfiniBand fabric to transparently achieve performance gains for existing socket-based networked applications  ...  In this paper we discuss an implementation of Zero Copy support for synchronous send()/recv() socket calls, that uses the remote DMA capability of InfiniBand for SDP data transfers.  ...  The servers are connected back-to-back through a 4X InfiniBand link running at double data rate (20Gb/s).  ...
