Abstract
A system and method for allocating physical memory in a distributed, shared memory system and for maintaining interaction with the memory using a reservation protocol is disclosed. In various embodiments, a processor node may broadcast a memory request message to a first subset of nodes connected to it via a communication network. If none of these nodes is able to satisfy the request, the processor node may broadcast the request message to additional subsets of nodes until a positive response is received. The reservation protocol may include a four-way handshake between the requesting processor node and a memory node that can fulfill the request. The method may include creation of a reservation structure on the requesting processor and on one or more responding memory nodes. The reservation protocol may facilitate the use of a proximity-based search methodology for memory allocation in a system having an unreliable underlying transport layer.
