Access to SDS@hd

SDS@hd ScientificDataStorage © University Heidelberg

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
