PDF Ebook Xgrid Programming Guide
This document describes the programming interfaces to Xgrid, Apple’s technology or distributed multiprocessing using multiple computers and multiple processors. If you are writing an application that can benefit from being executed on multiple processors simultaneously, you should read this document.
Xgrid allows you to execute programs using multiple computers—and multiple processors on a single computer—to perform multiple calculations in parallel. Xgrid is a generalized system, capable of assembling clusters of processors on demand, detecting and correcting failures, and parceling out parallel tasks as needed for general-purpose parallel computing on multiple systems. The Xgrid controller is a feature of Mac OS X Server, but any computer with Mac OS X (version 10.4 and later) can submit jobs to Xgrid or act as an agent to carry out Xgrid computations.
