[openib-general] Sockets Extensions Completed

[Michael Krause]

FYI.....The specification can be found at:

http://www.opengroup.org/bookstore/catalog/c050.htm

Use of this new interface will enable Sockets based applications to fully 
exploit the performance of RDMA interconnects through the SDP wire 
protocol.   This API also provides explicit memory management taking some 
of the guesswork out of this thorny problem which can result in some 
performance loss and implementation complexity within the SDP layer.

Extended Sockets API (ES-API), Issue 1.0

The Extended Sockets API (ES-API) Technical Standard provides extensions to 
the traditional socket API to support improved efficiency in network 
programming. The ES-API includes: synchronous IO and control operations on 
sockets; event queue-based management of asynchronous operations; and 
pre-registering of memory regions that will be the subject of IO 
operations. These facilities are intended to support: improved efficiency 
when dealing with high numbers of socket file descriptors; 'zero-copy' 
transmit and receive operations; and improved buffer management. The ES-API 
also includes routines that provide asynchronous IO and control operations, 
asynchronous operation management, and memory registration functions for 
applications manipulating sockets.
