Starting Akuna

Launching Akuna

Once Akuna is installed, launch Akuna on a PC by double-clicking the Akuna shortcut icon on the desktop. Akuna can also be started from the Start menu.

On a Mac, the Akuna icon is accessed under Applications. The icon can be dragged and dropped to the desktop or the dock if desired. Launch Akuna by selecting it under the Applications menu, or double clicking on the icon.

A Warning Notice window will pop-up (Figure 1), click Ok to proceed.

Figure 1. Warning Notice.

Requesting an Account

The Akuna UI is installed locally on the user's machine and it provides a front end to the simulation workflow. This framework has a client-server architecture, which means that users require access to the server in order to access the functionality provided through the Akuna interface. An account request can be made when launching Akuna. Beneath the login information on the splash screen, is a Request Account. Users can click on this text to bring up a web page where an account request can be completed (see Figure 2). Forgotten password and username requests can also be accessed from the login screen.

Compute Server Accounts

Once an account is obtained, users can access all toolsets available through the Akuna UI. To launch simulations, however, users will heed to have access to a compute server where the simulation controller and simulator executables reside (Figure 3). It is possible to launch simulations on the localhost or a computer on the local network. For high performance computing (HPC) applications, however, an account on a supercomputer may need to be obtained.

For ASCEM users executing Amanzi, access to DOE's NERSC computer (e.g., Hopper, Edison) may be granted. This account access is necessary for launching simulations, as the Akuna server does not accept simulation jobs. Akuna is only responsible for transferring the simulation files to the remote compute server. Information on requesting a NERSC account can be found on the Akuna download page. In addition, local computer resources can be used, but users must request from the development team that the computer be registered on the Akuna server.

    Figure 3: Schematic of user access to remote resources. The user installs the Akuna Client locally, but requires an account on the Akuna server, as well as a distinct account on a server which has the simulator (e.g., Amanzi) and simulation controller (Agni) already installed. Separate login credentials will be required.

The main Akuna application window (Home) opens (Figure 4). From this window the user can access some of the basic features of the application including:
  • Taking a tutorial
  • Browsing the projects
  • Creating a Team
  • Reporting a problem
  • Getting more Information on Akuna
