Java Grande: Role of Java in Large Scale Computations

We discuss the different ways Java can be used in a computational science programming environment Graphical User Interface and client side interactive analysis systems including visualization Server side Coarse Grain Coordination -- management and linkage of distributed objects Coding of computational science programs in both parallel and sequential style

We describe the implied metaproblem and metacomputer architecture

We relate Java to CORBA and COM distributed object models

We describe Java Grande Forum
