  3. backend backend SOAPwrapper Have Portal – will make Web Service • Gateway (http://www.gatewayportal.org) is a relatively mature portal supporting Job submission, management and some visualization for codes like ANSYS – developed for DoD HPC centers Add CastorJava to XML Globusrcp/rsh Will replacehistorical CORBA By EJB CORBA Corba middle tierSECIOP withJava modules JSP SSL Available For GCE testbedJanuary 2002 WSDL

  4. Have Collaboration System – will build Collaborative Portal • http://ararat.ucs.indiana.edu:8080 is Garnet collaboration system used for distance education and simple collaborative computing with Gateway • Education is a nice web service! • Can use with Access Grid • Garnet uses GXOS XML eventshttp://aspen.ucs.indiana.edu/project/gxos/schemas/gxosall.xsd supported by Java message service for synchronous and asynchronous publish/subscribe • Garnet will be integrated with JXTA using a common message queue middle tier with multiple dynamic event brokers • Gateway can use GXOS – need to understand evolving Grid event models – allows more powerful collaborative portal as can dynamically share any event type • GXOS/Grid Event Schema needs extension to describe base scientific data types (arrays as in XSIL HDF) and higher level (e.g. meshes as in ICE)
