It is possible to access your storage space on SDS@hd directly on the bwforCluster MLS&WISO. You can access your SDS@hd directory with a valid Kerberos ticket on all compute nodes. Kerberos tickets are obtained and prolongated on the login nodes. Before a Kerberos ticket expires, notification is sent by e-mail.
Direct access in compute jobs
- Fetch a Kerberos ticket on any login node with command: kinit (use your SDS@hd service password)
- Prepare your jobscript to use the directory /mnt/sds-hd/<your-sv-acronym>
- submit your job
Copying data from SDS@hd to a cluster workspace
Certain workflows or I/O patterns may require the transfer of data from SDS@hd to a workspace on the cluster before submitting jobs. Data transfers are possible on all login nodes:
- Fetch a Kerberos ticket on any login node with command: kinit (use your SDS@hd service password)
- Find your SDS@hd directory in /mnt/sds-hd/
- Copy data between your SDS@hd directory and your workspaces
- Destroy your Kerberos ticket with command: kdestroy
