Porting programs from the iPSC/860 to the AP1000

Abstract

This document contains descriptions and comparisons of the NX/2 Release 3.3 and CellOS Release 1.1 operating systems for the Intel iPSC/860 (and iPSC/1 and iPSC/2) and Fujitsu AP1000 scientific multicomputers respectively. The purpose of this document is to describe the features and idiosyncracies of the two operating systems, and the machines on which they run, for the purpose of easing the process of porting applications from the iPSC/860 to the AP1000 or vica versa. The sections of this document each describe one particular facet of the operating systems (such as message sending, or input/output facilities), and contrast the facilities provided by NX/2 and CellOS and give recipes and hints for converting code that uses the particular facilities.
