Xgrid Enabled OpenMPI, LAM-MPI, and MPICH2

Abstract - In this document we outline some simple (and sometimes slightly dirty)

methods for setting up a MAC OS X 10.4 cluster for Xgrid (SETI@home style processing)

and three popular versions of MPI, i.e., OpenMPI, LAM-MPI, and MPICH2. Our sample

setup consists of one MAC OS X 10.4 server and three MAC OS X 10.4 (client) Intel

based MAC Mini computers. There are many resources available on the Internet that try

to make parts of such installations documented, however many of them do not work on

OS X 10.4, do not provide enough information, or provide too much information (thus

obfuscating the essence). We will try to make this document a usable reference for an

average computer user with some general *nix and/or MAC user interface knowledge.

This document is by far not a complete or a comprehensive guide to Mac OS 10.4 and in

many cases we will use some tricks to get to our goal. There obviously is no liability

assumed for any of the procedures described below and many of them do not consider

security to be a major problem as our cluster is sitting behind a firewalled NAT router.

1. Introduction

We will start our journey with some notes on installing MAC OS X 10.4 Server (from

now on referred to as S10.4). Next we describe setting up Xgrid. We then proceed to

creating a common nfs directory (readable and writable) that all nodes will see at the

same place in their directory structure (necessary for OpenMPI, LAM-MPI, and

MPICH2). Setup of OpenMPI will follow. We then show a quick method for installing

LAM-MPI and MPICH2 in the next consecutive sections. Finally, we describe the setup

process of a simple LDAP Open Directory so the S10.4 serves users and directories for

the 10.4 Clients (C10.4).

Our sample physical setup consists of a dual core Intel MAC Mini running the S10.4

and three single core Intel MAC minis running C10.4. They are all connected via Gigabit

Ethernet to a NAT router with DHCP capabilities (on a 192.168.x.x domain). The names

we will use are: mmac-servr00, mmac01, mmac02, and mmac03. In OS X, computers in

the same Ethernet domain can see each other using the “local” domain, thus the

computers can ping or connect to each other by the names: mmac-servr00.local,

mmac01.local, mmac02.local, and mmac03.local. In our setup we also use a Mac mini

look-alike IOGear MiniView KVM switch for simple access to the MAC Minis.

The References section contains links to online documents and resources that were

extremely helpful when setting up our cluster. We will try to do our best to reference
