Architectural overview of HaL systems

Abstract

This paper gives a high-level, architectural overview of a line of 64-bit SPARC based workstations and servers designed by HaL Computer Systems. It discusses target applications, highlights of the SPARC V9 instruction set, HaL-specific instructions and a highly scalable multi-processor system architecture. The paper concludes with a summary of 64-bit software compatibility issues, system performance and reliability/availability/serviceability features.
