In linux kernel since version 2.6.26 (release Date: 2008-07-13)  
An SGI machine can be divided into multiple Single System
Images which act independently of each other and have
hardware based memory protection from the others. Enabling
this feature will allow for direct communication between SSIs
based on a network adapter and DMA messaging.
