Gateway Support of Simple Standalone Codes

• Core capabilities allow simple wrapping of existing codes

• Program objects is defined as an XML file e.g. my favorite physics simulation on my PC becomes:<program name=“physicssimulation1”> <run domain=“npac” machine=“maryland” type=“pc”  os=“nt” >c:\myprogs\a.out</run><input button=“prog1” toolbar=“physics” type=“htmlform” > <name>userinput</name><field default=“10” maximum=“100000” >iterations</field> ………… </input> <output> …</output>  </program>

• Gateway generates a distributed object with

  • the button prog1 in physics toolbar
  • This button generates HTML form reading parameters
  • Form input data are checked and backend code activated
  • Parameters can be accessed by running code through Gateway linked library (call getparm(”iterations”) etc.)
