US 2014/0006724 A1 · EFFICIENT MEMORY MANAGEMENT FOR PARALLEL SYNCHRONOUS COMPUTING SYSTEMS

Abstract

Technologies relating to efficient memory management for parallel synchronous computing systems are disclosed. Parallel synchronous computing systems may include, for example, a host, a memory management subsystem, and an array of processing units adapted to execute in parallel. Memory management may be implemented at least in part via the memory management subsystem. A memory management subsystem may include one or more memory subsystem layers deployed between the host and the array of processing units. Each memory subsystem layer may have a local memory accessible by entities (whether the host or another layer) above the memory subsystem layer; and a memory controller adapted to manage communications between the entities (whether another layer or the processing units in the array) below the memory subsystem layer.

Dependent claims

A memory management subsystem adapted for deployment in a parallel synchronous computing system, the parallel synchronous computing system comprising a host, the memory management subsystem, and an array of processing units, the memory management subsystem comprising:

at least one memory subsystem layer adapted for deployment between the host and the array of processing units, wherein the at least one memory subsystem layer comprises:
a memory controller;
and
a local memory;
wherein the at least one memory subsystem layer is adapted store, in the local memory, either:
a continuous image of concatenated memories of the processing units in the array;
or
a continuous image of concatenated memories of components in a memory subsystem layer between the at least one memory subsystem layer and the processing units in the array;
wherein the memory controller is adapted to manage communications between the local memory and either:
the processing units in the array;
or
the components in the memory subsystem layer between the at least one memory subsystem layer and the processing units in the array.

A memory management method adapted for deployment in a parallel synchronous computing system, the parallel synchronous computing system comprising a host, a memory management subsystem comprising at least one memory subsystem layer deployed between the host and the array of processing units, and an array of processing units, the memory management method comprising:

storing, by the at least one memory subsystem layer in a local memory within the at least one memory subsystem layer, either:
a continuous image of concatenated memories of the processing units in the array;
or
a continuous image of concatenated memories of components in a memory subsystem layer between the at least one memory subsystem layer and the processing units in the array;
and
managing, by a memory controller in the a at least one memory subsystem layer, communications between the local memory and either:
the processing units in the array;
