Managing shared memory used by compute nodes

Abstract

A technology can be provided for managing shared memory used by a plurality of compute nodes. An example system can include a shared globally addressable memory to enable access to shared data by the plurality of compute nodes. A memory interface can process memory requests sent to the shared globally addressable memory from the plurality of processors. A memory write module can be included for the memory interface to allocate memory locations in the shared globally addressable memory and write read-only data to the globally addressable memory from a writing compute node. In addition, a read module for the memory interface can map read-only data in the globally addressable shared memory as read-only for subsequent accesses by the plurality of compute nodes.
