Workspaces
workspaces are only available at amplitUDE
The workspace tool provides storage space for computations on the parallel file system. They are meant to keep data for a limited time – but usually longer than the time of a single job run. It is not meant for permanent storage, hence data in workspaces is not backed up and may be lost in case of problems on the storage system. Please copy/move important results to $HOME or some disks outside the cluster.
For details about the tool see here
About workspace
A workspace is formost a directory created on behalf of the user with some properties
it has an ID selected by the user

Default settings and limits
TBA
Create workspace
To create a workspace you need to state <ws_name> of your workspace and
ws_allocate <ws_name> <lifetime>
You can enable a reminder mail some days before your workspace expires and is deleted using the options -r
ws_allocate -r <days before ws expires> -m <mailaddress> <ws_name> <lifetime>
For more information read the program’s help, i.e. ws_allocate -h
.
If you don’t want to add these options each time to your ws_allocate
command you can add these information to the ~/.ws_user.conf
configuration file:
mail: <mailaddress>
reminder: <days before ws expires>
List all your workspaces
To list all your workspaces, execute:
ws_list
which will return:
Workspace ID
Workspace location
available extensions
creation date and remaining time
Find workspace location
Workspace location/path can be prompted for any workspace ID using ws_find
, in case of workspace <ws_name>
:
ws_find <ws_name>
Extend lifetime of your workspace
As each workspace has an expiration date, its lifetime is limited. To extend the lifetime by the <duration>
(given in days) of an existing workspace <ws_name>
within the policies set by the administrators, execute:
ws_extend <ws_name> [<duration>]
Note: The value <duration>
extend the lifetime from now.
Remind your workspace expiration date
To take care of your workspaces an their lifetime, the command ws_send_ical
can be execute for a existing workspace <ws_name>
:
ws_send_ical <ws_name> <your_Email-address>
It checks the remaining time of a given workspace <ws_name>
and send a calendar invitation to the Email address <your_Email-address>
. If you are using a mail programm with an integrated calendar function, you can accept this event and your calendar will remind you …
Delete your workspace
In addition to the automatic deletion process at the end of the service life, the user can initiate an early deletion of their workspace:
ws_release <ws_name>
