Foil 22 Basic HPcc Strategy

From Java Grande: Role of Java in Large Scale Computations NPACI Summer Institute on Parallel Computing -- August 21 98. by Geoffrey C. Fox


1 HPcc is High Performance commodity computing
2 Encapsulate services (from databases to instruments to MPP's) as middle tier distributed objects using an approach that will evolve to COM/CORBA in future but is deployable today
  • JDBC (Java Database Connectivity) links to databases
  • (Java) web server/CORBA JWORB interfaces to compute modules
  • Client Side Javabean visual interfaces
  • Server Side Enterprise Javabeans
3 Establish Java Frameworks and Equivalent CORBA Facilities
  • for Computing Services
  • Distributed Scientific Objects DSO -- Compute and Data sectors --- with several domain specific interfaces inherited from DSO
4 This already gives you an approach to seamless access and a framework for composing complex metaproblems by linking programs together or programs to databases
