It is possible to access your storage space on [http://sds-hd.urz.uni-heidelberg.de SDS@hd] directly on the bwforCluster MLS&WISO. |
|||
You can access your SDS@hd directory with a valid Kerberos ticket on all compute nodes '''except standard nodes'''. Kerberos tickets are obtained and prolongated on the data mover nodes data1 and data2. Before a Kerberos ticket expires, notification is sent by e-mail. |
|||
== Direct access in compute jobs == |
|||
* Login in to a datamover, i.e. "ssh data1" or "ssh data2" (passwordless) |
|||
* Fetch a Kerberos ticket 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 on data mover node == |
|||
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 the data mover nodes data1 and data2: |
|||
* Login to a data mover node with command: "ssh data1" or "ssh data2" (passwordless) |
|||
* Fetch a Kerberos ticket 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 |
|||
* Logout from data1 for further work on the cluster |
