Abstract

Global Arrays (GA) combines the better features of shared-memory and message-passing programming models, leading to both simple coding and efficient execution. The key concept of GA is that it provides a portable interface through which each process in a MIMD parallel program can asynchronously access logical blocks of physically distributed matrices, with no need for explicit cooperation by other processes. The use of GA is illustrated in the context of computational chemistry applications, and the use of a GA visualization tool is described.
