3. © 2008 Pittsburgh Supercomputing Center TGUP (TeraGrid User Portal) Motivation –Aggregates and Simplifies access to TG information & services –Control panel for active TG users with accounts Daily resource for TG users – check allocations, view system information, submit consulting ticket, view documentation etc. –Make using TG simple, like a financial portal –Increase productivity of TeraGrid researchers – do more science! Vision –The TeraGrid User Portal will continue to integrate important user capabilities in one place: Comprehensive TeraGrid allocation and account management TeraGrid user documentation, consulting, training info, knowledge base Comprehensive RP resource information services, Simple access to GIG and RP interactive grid usage – logging in, remote viz, etc. Potentially, all user services and interactions (e.g., surveys, online training, real-time consulting, interactive data mining, remote visualization, etc.)

4. © 2008 Pittsburgh Supercomputing Center Accessing TeraGrid User Portal When you get your accounts packet you will have a portal account (username and password) listed The portal account is also your TG-Wide login From the portal you can access any allocated TeraGrid resource.

10. © 2008 Pittsburgh Supercomputing Center Resources Systems Monitor –View system information that includes CPUs, jobs running in queue HPC Queue Prediction –Can predict questions like What is the chance my job will begin running within a certain time? How long will it take my job to begin running? Remote Visualization –Offers interactive visualization capabilities for users needing to analyze very large data sets Science Gateways –domain-specific computing environment, typically accessed via the Web, that provides a scientific community with end-to-end support for a particular scientific workflow Data Collections –Data collections represent permanent data storage that is organized, searchable, and available to a wide audience, either a collaborative group or the scientific public in general

15. © 2008 Pittsburgh Supercomputing Center What is Single Sign on? Single Sign On (SSO) is a sign on method that provides access to TeraGrid resources. Once a session is initiated, you will not be asked for other passwords throughout the duration of the session. Different SSO methods –Through the TeraGrid User Portal –From Command Line of a TeraGrid Resource

16. © 2008 Pittsburgh Supercomputing Center Web Based SSO via TeraGrid User Portal Make sure you are logged into the TeraGrid User Portal Go to ‘My Teragrid’ tabMy Teragrid Go to the ‘Accounts’ linkAccounts Resources you have access to will be indicated by a ‘login’ link Click on the ‘login’ link of the resource you would like to login to

17. © 2008 Pittsburgh Supercomputing Center Web Based SSO via TeraGrid User Portal Initially a blank terminal window will appear in your web browser The window will fill with text indicating that you have successfully been logged into the resource of your choice

18. © 2008 Pittsburgh Supercomputing Center SSO (Non Portal) from a TeraGrid Resource SSH to the TeraGrid resource that you've chosen as a starting point using the instructions for that resource from your account information packet. At the command line, type grid-proxy-info. If you already have a proxy, you can start computing. If you receive an error saying that you do not have a temporary proxy, then continue below. (If this is your first time logging in to a TeraGrid resource, you can skip this step.) Run myproxy-logon -l You will get a prompt to enter your MyProxy passphrase. Use the TeraGrid-wide (Portal) username and password that you received in your packet for this step. Run grid-proxy-info again. To verify proxy Now you can access TG resources without a password using gsissh

20. © 2008 Pittsburgh Supercomputing Center Where to get Help First, try searching the Knowledge Base or other Documentation If that doesn’t help submit a ticket –Send an email to help@teragrid.orghelp@teragrid.org –Use the TeraGrid User Portal Go to the ‘Consulting’ tab

21. © 2008 Pittsburgh Supercomputing Center Submitting a Ticket Your user information will be autofilled Just fill out the rest of the form Make sure you include a detailed problem description before submitting the form

22. © 2008 Pittsburgh Supercomputing Center Softenv What is it? –A way to manage your software environment on TeraGrid machines. In other words, you can use it to configure which applications and packages are available to you when you log onto a TeraGrid machine Why use it? –For beginning users it is mostly important to enable non web based single sign-on (via myproxy-logon). Using single sign-on makes possible high speed gridftp-enabled file transfers between different TeraGrid sites (usually for tens of Gigabytes or more).

23. © 2008 Pittsburgh Supercomputing Center Softenv How to use it –To enable the use of myproxy-logon for single sign-on just do this (you only need to do it once): Log in to the machine that you will run myproxy-logon from If there is a.nosoft file in your home directory, remove it See if there is a.soft file in your home directory –If not, issue the following command from your home directory: »cp $TG_EXAMPLES/.soft.ctssv3.soft »resoft »In some cases it may be necessary to logout and back in –If there is a.soft file already, you should be good to go. If you have trouble, however, then rename the existing.soft to.soft.orig and then follow the steps above. If you need to change the default software environment, see: http://www.teragrid.org/userinfo/jobs/softenv.php

24. © 2008 Pittsburgh Supercomputing Center Security – The Basics You are responsible for your account. Do not share accounts Protect your password(s) –Includes not sharing passwords, not writing passwords down where they can be easily found, and not using tools which expose passwords on the network –This includes private keys Appropriate Behavior Report Suspicious Activity If you have any suspicion that your account or personal computer has been compromised send email to help@teragrid.org immediatelyhelp@teragrid.org
