High performance computing will not be immune from this paradigm shift. More specifically, as our current and future Internet continues to scale in both size and bandwidth, it is not unrealistic to think about applications that might incorporate 10,000 active components that are distributed over that many compute hosts. Furthermore, pressure from the desktop software industry will compel us to integrate the applications that run on supercomputer systems into distributed problem solving environments that use object technology. Metacomputing systems consisting of MPP servers, advanced, networked instruments, database servers and gigabit networks will require a robust and scalable object model that support high performance application design.
In this position paper, we describe the important characteristics of high performance, "Metacomputing" applications that arise in large scale science and engineering computation. We will then describe the limitations of some of the current component architectures based on CORBA, ActiveX, and Java Beans/Studio when applied to this class of problem. We conclude with a series of suggestions for building a more robust component model that will scale to the application described here.
