Try eSDO algorithms, visualization tools and data centre prototype
Step-by-step Instructions

Pre-requisites

Download the AstroGrid workbench for access to the Task Launcher, HelioScope, and the Workflow Builder. Apply for an AstroGrid account to use the Task Launcher and Workflow Builder; no account is needed for use with HelioScope or the eSDO visualization tools.

Try Solar Algorithms

Requirements: Start the AstroGrid Workbench and click "Task Launcher" once. To see all eSDO algorithms and resources, type "eSDO" in the Find text box and click "Search". Click the checkbox next to the desired application to select it from the list.

How to Run Algorithms with the AstroGrid Task Launcher

  1. Finding Algorithms with Task Launcher
    • Start the AstroGrid Workbench and click "Task Launcher" once.
    • To see all eSDO algorithms and resources, type "eSDO" in the Find text box and click "Search".
    • Open an application from the task launcher list by clicking the checkbox to the left of the application's name.
    • A task launch window will open displaying a table of inputs and outputs. The table contains 5 columns:
      • Name - name of input or output
      • Value - empty textfield that should be filled in with the name of a file, a string, or a number (integer or float)
      • Reference file - checkbox indicating reference to a remote file. A remote file can be a URL, a file on a local machine, or a file in MySpace. If the input is a file (or the output will be a file), click the reference box and follow the instructions in the next section. If the input or output is a variable (such as a string, integer, float, datetime, etc), leave the reference box unchecked.
      • Repeating parameter - check this box for repeating parameters. For example, if an input parameter "inputImages" could accept a list of 1 to n image filenames, check the repeating parameter box and enter one input per row. None of the eSDO algorithms currently involve repeating parameters.
      • Delete optional parameter - check this box only if you wish to delete an optional parameter. Hover the mouse over a parameter's name to see a description of the parameter. The parameter's description will specify whether the parameter is optional.
  2. Specifying Files as Inputs or Outputs
    • In the task launcher application window, find the table row describining the name, value, reference box, repeating parameter box and delete box of an input (or output) that requires a filename.
    • Click the input's reference box once. A new window will open that says "Select input location" (or "Select output location").
    • Input files can be chosen from 3 locations: Local Disk, MySpace or URL. Click the appropriate tab at the top of the window.
      • Local Disk - navigate to the file on your local machine
      • MySpace - navigate to the file in your MySpace directory and click OK.
      • URL - type the remote URL pointing to the input file and click OK.
    • Output files can be written to MySpace in this version of the AstroGrid workbench.
      • Click once the name or folder icon or the MySpace directory where the output file should be written. New subfolders can be created by clicking an existing folder and then clicking the new folder icon (folder next to a "+") at the top lefthand of the window.
      • Now click the new file icon (white rectangle next to a "+") at the top lefthand of the window.
      • Enter a name for the new file and click OK twice.
  3. Specifying Variables as Inputs
    • Double click the textfield in the input's Value column. Type the input's number or string and then click outside the textfield.
  4. Launch the Application
    • Click the icon of a white arrow inside a green circle once. This icon is in the upper lefthand of the task launcher window.
    • The status window at the bottom of the task launcher window should say "Executing". Next, a VO Lookout window will open.
    • The VO Lookout window lists all recent tasks, queries and workflows submitted by your account. The most recent activity will be shown in blue; click it to see the status of the activity (pending, initialized, running, completed, error) in the main VO Lookout window.
  5. Finding a Different Application
    • Click "Chooser" on the lefthand side of the Task Launcher window. Submit another text search in the Find box.
