High Performance Bulk Data Transfers Using the SSH Protocol

Time 01/22/08 02:40PM-03:00PM

Session Abstract

SSH is a widely used multipurpose application used for both interactive shells and a transport layer mechanism. However, its usefulness as a bulk data transport tool is limited by two factors: an undersized applications layer receive window and an inability to make use of multicore processors. While the receive window issue has been addressed by HPN-SSH (August 2005 Joint Techs) the widespread adoption of multicore architectures has created a situation in which the application is limited to a fraction of the available compute resources available to it. This necessarily limits throughput and leads to inefficient utilization of network capacity. The authors will discuss the impact of these factors on performance, present a solution in the form of Threaded HPN-SSH, discuss its applicability for use in HPN environments, and outline future work on developing SSH as a high performance middleware transport mechanism.
