• UNCW GUI for Workflow Management
• www.gridnexus.org

Overview

• Based on Ptolemy II
• Use only SDF director
• Provides an additional scripting layer
• JXPL layer is similar to LISP, based on XML
• Composition generates the JXPL script
• Real execution performed by JXPL processor.
• JXPL Processor
• Local client machine
• Remote OGSA service, RMI service, HTTP service
• Creation of new module/actor
• Create java primitives module
• Create composite actor, new primitives from
  existing module

JXPL Example

• ltjxpllistgt
• ltjxplprimitive nameArithmeticgt
• ltjxplproperty nameoperation
  valueadd/gt
• lt/jxplprimitivegt
• ltjxplinteger value1/gt
• ltjxplinteger value2/gt
• lt/jxpllistgt
• ( 1 2)

4
Samples (Features)

• Basic Math/Arithmetic/Logic
• IsPrime
• (Do Until loop, Comparison , Prog primitives)
• Make it composite/library
• Factorial
• (Composite, Defun, Recursion)
• Fetch GoViz
• (Web service Client)
• Chemistry example
• (File Input, Transform File, Local exec),

5
Untested Features

• Grid Execution
• OGSA DAI
• Grid Data Services
• Remote JXPL data, access and execution
• Creation of java primitives

Summary

• Basic functionalities working including Web
  services and Local execution for legacy
  application
• Creation of new module by composition can be
  performed, but no source/sample for java
  primitives
• Unable to test the Grid/OGSA features, and remote
  JXPL processors
• Future Application Targets
• Animation Rendering, Bioinformatics, Primality
  Proving, Computational Chemistry
• Interesting feature JXPL
