Configure BLADED Jobs on PBS

Prerequisites

External storage

• The external storage server must be network-reachable from Windows compute nodes.
• The storage protocol must support both NFS and CIFS.
• CIFS must allow the fastone user to access the storage directory. The password is <FASTONE_PASSWORD>. See the Password Retrieval Guide. If you cannot access it, contact the relevant customer service manager, delivery manager, or technical support staff.

Steps

Install node dependencies

• Minimum PBS Node Dependencies

Enable the PBS scheduler on the platform

• Refer to the knowledge base SOP for enabling the PBS scheduler to run Bladed applications.
  • Note: When enabling the PBS scheduler, select the fastone user as the scheduler user.

Register nodes with the platform

• Note: On the Host Management page, when creating a new host, add the node with username set to fastone.

PBS cluster

• Shared storage mount path:
  • Ensure the shared storage directory /fs/users is readable and writable by the fastone user, for example with chmod -R 777 /fs/users, or add the fastone user to the sudoer group. Replace /fs/users with your actual shared storage path.

Task configuration

• Configure the application and run tasks:
  • Prepare a Bladed CWL document.
  • Copy the corresponding CWL file to the fastone platform. See the relevant documentation for usage details.

Common issues

• Execution user:
  • The task execution user is fastone, and it must be fastone.
• Shared directory mount:
  • On Windows, the mount defaults to drive Z:.

Cluster errors

1. Error message: error step: run cifs
   Cause: CIFS mount failed. Check whether the CIFS configuration is correct. If Fastone Samba is used, refer to the Samba configuration section.

2. Error message: node: xxxxxx: win private key The system cannot find the path specified.
   Cause: Windows has not logged in as the fastone user to configure SSH. See the minimum PBS node dependency guide, specifically the section on configuring fastone SSH.
