TORQUE Administrator's Manual - Server Node File Configuration

Server Node File Configuration

Basic Node Specification

In order for the pbs_server to communicate with each of the moms, it needs to know which machines to contact. Each node which is to be a part of the batch system must be specified on a line in the server nodes file.  This file is located at $TORQUEHOME/server_priv/nodes.  In most cases, it is sufficient to specify just the node name on a line as in the following example:

server_priv/nodes
node001
node002
node003
node004

Specifying Node Count

   If the compute node has multiple processors, specify the number of processors with np=<number of processors>. For example, if node001 has 2 processors and node002 has 4:

server_priv/nodes
node001 np=2
node002 np=4
...

Specifying Node Features (aka Node Properties)

   Node features can be specified by placing one or more whitespace delimited strings on the line for the associated host as in the example below:

server_priv/nodes
node001 np=2 fast ia64
node002 np=4 bigmem fast ia64 smp
...

   These features can be used by users to request specific nodes when submitting jobs.  See Scheduling Jobs with Node Features for more information.
