+You can log out after submitting the job. You will receive an email once the job becomes active.
+
+== Jupyter Notebook Access Information ==
+
+Once the job becomes active, you will receive an email like below:
+{{{
+Jupyter is running at cypress01-058
+token: 38e3c6cdf28b9d691677882cfcf62fbd217d35e1de7cc909
+
+Open a terminal and run the following command to create an SSH tunnel:
+ssh -L 8888:127.0.0.1:8888 -J [email protected] cypress01-058
+
+Copy and paste below to your web browser to access Jupyter Notebook:
+http://127.0.0.1:8888/?token=38e3c6cdf28b9d691677882cfcf62fbd217d35e1de7cc909
+}}}
+
+== Create an SSH Tunnel ==
+
+Open a terminal and run the command in the email, for example,
+{{{
+ssh -L 8888:127.0.0.1:8888 -J [email protected] cypress01-058
+}}}
+This will create an SSH tunnel from your local computer to the Cypress computing node.
+You may need to type a password to login Cypress.
+
+== Access Jupyter Notebook ==
+
+After logging in, keep the terminal open. Copy and paste the URL from the email into your web browser, or click the link to access the Jupyter Notebook.
+
+=== Start R session ===
+
+Select “New → R” from the drop-down menu in the upper-right corner of the Jupyter Notebook interface.
+
+=== When SSH connection lost ===
+
+When your SSH tunnel session is disconnected, you can still access your Jupyter Notebook session as long as the job is still running. If this happens, recreate the SSH tunnel and reload your web browser or reconnect using the original URL.
+
+=== Quit Jupyter Notebook Session ===
+
+Select “File → Shut Down” from the drop-down menu in the upper-left corner of the Jupyter Notebook interface.
