WWW / /PDEPACK is a World Wide Web server that provides a sophisticated problem solving environment for partial differential equations (PDEs).It incorporates over 100 solvers of various types which cover all the common PDE applications in 2 and 3 dimensions.WWW / jPDEPACK is a subset of Parallel ELLPA C!( in that not all the solvers are included and it.is an extension of Parallel ELLPACKin that it allows for web based use.Parallel ELLPACK is an existing problem solving environment (see Section 3 for more details) that is now in alpha testing.A prototype of WWW I/PDEPACK is now operational but its network performance is not yet satisfactory and its software generality is too limited (it now requires the user to have an X server).The goal of this project is to implement the scenario illustrated in Figure 1.A user on the net accesses WWW / /PDEPACK and the user interface is exported back.This interface is implemented in a net infrastructure code (e.g., Java from Sun) so it can run on any internet connected machine.This interface is large but still a tiny fraction of the entire WWW / jPDEPACK system.The user fonnulates the PDE application using the interface and then it is solved at the server site.The server, in turn, accesses other servers (e.g., parallel machines) on the net during the solution process.The results are then returned to the user.
