====Portal Login====
An [[ https://openondemand.org | OpenOnDemand ]] web portal is available at [[ https://pinnacle-portal.uark.edu ]].  ''pinnacle-portal'' requires a Uark id for login at this time.  If you go to the web page, a login popup will accept your Uark ID (no @uark.edu) and Uark password.

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

''Files'' is an Explorer-like GUI of your home directory which does upload and download to the connected workstation.

''Jobs'' shows your queued and running jobs on all clusters know to the portal.

''Clusters'' runs an ssh terminal emulator in the browser for shell access. You can select ''pinnacle'', ''trestless'', 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, selectable as ''comsol'', ''elmer'', ''matlab'', ''ovito'', ''pqs'', ''rstudio'', ''jupyter notebook'',or ''vmd'' on ''pinnacle''.  

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