Read-coherent group memory

Abstract

A data distribution system includes a data distribution module and at least two host-bus adapters coupled to the data distribution module. The data distribution system includes a memory-management system including a plurality of memory regions. The memory-management system is coherent across the plurality of memory regions and an absolute address of each of the plurality of memory regions accessed by a same offset.

What is claimed is: 
     
         1 . A method, comprising operating a data distribution system including
 initializing a memory-management system that is coherent across a plurality of memory regions; and   accessing an absolute address of each of the plurality of memory regions by a same offset.   
     
     
         2 . The method of  claim 1 , wherein the plurality of memory regions include heterogeneous memory regions. 
     
     
         3 . The method of  claim 1 , wherein the plurality of memory regions define a group memory. 
     
     
         4 . The method of  claim 1 , further comprising paging including dividing a group memory into a plurality of pages. 
     
     
         5 . A non-transitory computer readable media comprising executable programming instructions for performing the method of  claim 1 . 
     
     
         6 . An apparatus, comprising: a data distribution system including a data distribution module and at least two host-bus adapters coupled to the data distribution module, wherein the data distribution system includes a memory-management system including a plurality of memory regions,
 wherein the memory-management system is coherent across the plurality of memory regions and   wherein an absolute address of each of the plurality of memory regions accessed by a same offset.   
     
     
         7 . The apparatus of  claim 6 , wherein the plurality of memory regions include heterogeneous memory regions. 
     
     
         8 . The apparatus of  claim 6 , further comprising another data distribution module coupled to the data distribution module. 
     
     
         9 . A network, comprising the apparatus of  claim 6 . 
     
     
         10 . An interconnect fabric, comprising the apparatus of  claim 6
