Accessing hpc_config

Use a text editor to edit the hpc_config file directly. This file must be located in a directory within a file system that is mounted read/write/execute accessible on all the other nodes in the cluster. A template for hpc_config is provided on the Sun HPC ClusterTools 3.0 distribution CD-ROM to simplify creation of this file.

Before starting the installation process, you should copy this template to a directory on the node chosen to be the installation platform and edit it so that it satisfies your site-specific installation requirements. Choose a node to function as the installation platform and a home directory on that node for hpc_config.

The directory containing hpc_config must be read/write/execute accessible (777 permissions) by all the nodes in the cluster.

The hpc_config template is located in

/cdrom/hpc_3_0_ct/Product/Install_Utilities/config_dir/hpc_config

To access hpc_config on the distribution CD-ROM, perform the following steps on the node chosen to be the installation platform:

1. Mount the CD-ROM path on all the nodes in the cluster.

2. Load the Sun HPC ClusterTools distribution CD-ROM in the CD-ROM drawer.

3. Copy the configuration template onto the node.

   # cd config_dir_install # cp /cdrom/hpc_3_0_ct/Product/Install_Utilities/config_dir/hpc_config .

   config_dir_install is a variable representing the directory where the configuration files will reside; all cluster nodes must be able to read from and write to this directory.

4. Edit the hpc_config file according to the instructions provided in the next section.

If You Have Already Installed the Software

If you have already installed the software, you can find a copy of the hpc_config template in the directory /opt/SUNWhpc/bin/Install_Utililites/config_dir.

If you are editing an existing hpc_config file after installing the software using the graphical installation tool, the hpc_config file created by the tool will not contain the comment lines included in the template.
