Servicing indirect data storage requests with multiple memory controllers

Abstract:

Embodiments of the invention include method, systems and computer program products for servicing indirect storage requests. Method includes decoding a storage request instruction and sending to a first one of a plurality of memory controllers an address represented by a first pointer associated with at least a portion of the storage request instruction. A first memory is used to read information associated with a second pointer contained at the address. The first memory forwards the storage request instruction to a second one of the plurality of memory controllers, wherein the second one of the plurality of memory controllers is associated with and/or manages a memory location represented by the second pointer. The second one of the plurality of memory controllers reads and forwards data associated with the storage request instruction to a processor using the second pointer. The processor writes the forwarded data in a destination register of the processor.
