 Explore a range of interactive applications to support your research tasks,

+==== HPC Usage Dashboard ====
+The HPC team has released a new dashboard integrated directly into OpenOnDemand.
+This dashboard provides a clear graphical overview of your resource usage and helps you better understand how you consume HPC resources.
+The dashboard is designed to help you with a quick and simplified view:
+  *   Track and understand your HPC usage
+  *   Identify your accounts and partitions
+  *   Compare consumption patterns within your PI
+  *   Navigate the HPC infrastructure more confidently
+You can access it via:
+*   **Accounting → my_hpc_usage**
+    (Available on [[https://openondemand.baobab.hpc.unige.ch|Baobab]], [[https://openondemand.baobab.hpc.unige.ch|Yggdrasil]], and [[https://openondemand.baobab.hpc.unige.ch|Bamboo]] OpenOnDemand instances.)
+{{:hpc:ood_accounting_tab.png?nolink|}}
+=== Quick Overview of Your HPC Environment ===
+The dashboard offers a graphical summary of your usage over a predefined period (from November to now).
+This gives you immediate insight into your consumption patterns.
+=== Slurm Account Information ===
+The dashboard displays:
+  *   A list of all Slurm accounts associated with your user profile
+  *   Clear identification of your **default Slurm account**, automatically used when no account is specified during job submission
+{{:hpc:ood_dashboard_hpc_usage_summary.png?nolink|}}
+=== Group and Partition Access Overview ===
+A summary table shows:
+  *   The HPC groups you belong to
+  *   Associated Slurm servers
+  *   Slurm partitions you can access
+This helps you understand which parts of the HPC infrastructure are available to you.
+{{:hpc:ood_dashboard_hpc_usage_private_ressources.png?nolink|}}
+=== Intra-PI Consumption Comparison ===
+A comparative graph displays resource consumption (in **Billing Units**) for:
+  *   You
+  *   Other users belonging to the same PI
+This allows you to see how computing resources are used within your research group.

 ===== Logout =====
 To Logout you need to close you browser and not only the current tab.
+===== Launching applications =====
+This documentation has been taken from https://docs.hpc.qmul.ac.uk/ondemand/
+After choosing from the available applications, you can requested the necessary resource for the session, and then click Launch.
+{{:hpc:hpc:resources.png?nolink&600|}}
+Typically, when requesting resources, you will be given the option to choose number of cores, maximum running time and memory per core. If multiple versions of the application are available, this may be offered too.
+For many use-cases, including non-computational visualisation, and many Jupyter/R Studio sessions, a maximum of 1 core will be used by the application.
+There is also the option to request an email to notify you when the job starts, in the case of sessions which require longer queueing time.
+For graphical applications, once the session is established, you have the option to alter the image quality and compression level. For most cases, using the defaults should be fine, but for precise graphical work, or taking screenshots, you may want to increase the image quality.
+{{:hpc:quality.png?nolink&600|}}
+<WRAP center round info 60%>
+Note also the **View only** link. OnDemand sessions are secure and confined only to you. However, you have the option to share a **read-only view** of your session for purposes of monitoring progress of a job with a collaborator or to demonstrate work to a colleague.
+</WRAP>
+==== Session persistence ====
+A session remains active for the time period you have requested it for. If you have finished your work, then we recommend that you close the application cleanly, followed by clicking Delete next to your session on My Interactive Sessions page. This will release resources back to the cluster.
+If you are running a graphical application which uses a desktop environment, any computation will continue even after the browser tab is closed. Clicking Launch again from the My Interactive Sessions screen will reconnect to the session.
+Closing a browser tab while running a web service session such as Jupyter  will interrupt computation, in the same way as it would if you did the same while running Jupyter locally on your own PC. Jupyter and both offer ways to save and checkpoint your work if you want to resume later.
