Final Report: Programming Models for Shared Memory Clusters

PDF Version Also Available for Download.

Description

Most large parallel computers now built use a hybrid architecture called a shared memory cluster. In this design, a computer consists of several nodes connected by an interconnection network. Each node contains a pool of memory and multiple processors that share direct access to it. Because shared memory clusters combine architectural features of shared memory computers and distributed memory computers, they support several different styles of parallel programming or programming models. (Further information on the design of these systems and their programming models appears in Section 2.) The purpose of this project was to investigate the programming models available on ... continued below

Description

Most large parallel computers now built use a hybrid architecture called a shared memory cluster. In this design, a computer consists of several nodes connected by an interconnection network. Each node contains a pool of memory and multiple processors that share direct access to it. Because shared memory clusters combine architectural features of shared memory computers and distributed memory computers, they support several different styles of parallel programming or programming models. (Further information on the design of these systems and their programming models appears in Section 2.) The purpose of this project was to investigate the programming models available on these systems and to answer three questions: (1) How easy to use are the different programming models in real applications? (2) How do the hardware and system software on different computers affect the performance of these programming models? (3) What are the performance characteristics of different programming models for typical LLNL applications on various shared memory clusters?
