JavaOne Grande Vision III

• Java thread model is insufficient for large scale parallelism

• Need to take experience from Grande community and provide

  • Near term bridges (MPI linked to Java)
  • Future Models (Jini linked to Grande algorithms)

• Performance is critical

  • Core Java technology such as Hotspot provides raw infrastructure but is not a complete solution

• Numerical computing has special needs in both

  • expressivity (e.g. complex types) and
  • performance/reproducibility as it is different from system programming (results are data dependent)

• Java Grande framework must address both low level (messaging, floating point coding) and high level interfaces (portals to simulations, immersive worlds …)
