====Portal Login====
An [[ https://openondemand.org | OpenOnDemand ]] graphical web portal is available at [[ https://pinnacle-portal.uark.edu ]] (if you are on UARK vpn or campus) or [[ https://hpc-portal2.hpc.uark.edu ]] (everywhere).  ``pinnacle-portal`` is subject to erratic operation of the university firewall and may not work even from campus.  If so, try ``hpc-portal2.hpc.uark.edu``. 

If you go to the web page of either portal, a login popup will accept your AHPCC id and password (Your id may be the first part of your email, use "rfeynman" not "rfeynman@caltech.edu") .  See [[ get_an_account ]] and [[ ssh_login ]] for more info on Uark accounts. **Note**: the pinnacle web portal is not available on Safari web browser. 

At the portal home page, you can select ''Files'', ''Jobs'', ''Clusters'', ''Interactive Apps'', or ''My Interactive Sessions''.

''Files'' is an Explorer-like GUI of your home directory which does upload and download to the connected workstation.  Common ''/home/user'' or CSCE ''/karpinski/user'' are selectable.

''Jobs'' shows your queued and running jobs on all clusters know to the portal (that is ''pinnacle'',''trestles'', and ''karpinski'').

''Clusters'' runs an ssh terminal emulator in the browser for shell access. You can select ''pinnacle'' or ''karpinski (CSCE)'' clusters.

''Interactive Apps'' allows X desktops to ''pinnacle'' or ''karpinski''.  This is the simplest way to run an X graphics program on the clusters.  There is also a ''GUIs'' menu that opens an X desktop and an graphical application on ''pinnacle'', selectable as ''comsol'', ''elmer'', ''matlab'', ''ovito'', ''pqs'', ''rstudio'', ''jupyter notebook'',or ''vmd''.

There is also a ''VM launcher'' on either ''pinnacle'' or ''karpinski''.  See [[ virtual_machines ]] for usage.
