Getting Started

Before you do anything else, you should read the enFuzion Manual to learn how to use enFuzion. Most of your questions can be answered there.

You might also like to look at the Questions Asked At Least Once document. If you are using PBS, check out the document Running PBS on Mahar.

Configuration

The Parallel Parametric Modelling Engine is composed of two servers and ~70 nodes at the Clayton campus of Monash University. For those interested, a page detailing the network setup has been created. That page contains a network diagram as well as explanation. It also has a very important note on the possible impact of a poorly written enFuzion plan which will use unnecessary network bandwidth. Please note that at this time 4 nodes have been extracted from the cluster for a private cluster used by researchers wanting to utilise nodes with some specific configuration.

The following explanation gives basic information on how to configure enFuzion for use with this particular setup. It does not give a tutorial on how to use the enFuzion program. For that, please read the enFuzion Manual.

Linux

The configured client machines are named node01-node50. The older machines are still to be configured for the new cluster.

The following is a sample enfuzion.nodes file to run processes under linux. Naturally you must replace username with your username. The first column lists the names of the machines. The last column containing "$node01" tells enFuzion to use the same password as is entered for node01.

node01 username
node02 username $node01
node03 username $node01
node04 username $node01
node05 username $node01
node06 username $node01
node07 username $node01
node08 username $node01
node09 username $node01
node10 username $node10

The cluster machines are all running Debian Linux. You can use ssh to login to mahar and the nodes (in fact it is strongly recommended that you use ssh rather then telnet). Users' home directories are NFS mounted on mahar and all the nodes on one of the partitions /u/cluster1 - /u/cluster3. In addition, each node has a /scratch partition (similar to the /tmp directory) which is approximately 22Gb in size. This area can be used by cluster users for local storage on each node to reduce network traffic.

Windows XP

If you intend to run processes under Windows XP you still start the jobs from mahar running linux. However, you must specify the WindowsNT option (yes, still use WindowsNT even though we're running XP) so that enfuzion knows the machines are running Windows, not linux.

There is currently no automatic way to determine if a machine is currently running Linux or Windows XP. However, a file is updated with a node's number whenever it is booted into XP, and this can be viewed using the command clientconfig on mahar. Due to the low demand for Windows XP, you will need to request machines to be booted into XP if you wish to use it.

node43 username WindowsNT
node44 username $node43 WindowsNT
node45 username $node43 WindowsNT
node46 username $node43 WindowsNT
node47 username $node43 WindowsNT
node48 username $node43 WindowsNT
node49 username $node43 WindowsNT
node50 username $node43 WindowsNT
