Common Component Architecture for High-Performance Computing

What’s the problem?

PPT Slide

The Common Component Architecture Requirements

The problem with existing Component Architectures

Who are we?

CCA Active Participants *

Scientific IDL provides OO interoperability to C, C++, Java, Python, Fortran 77/90

No plan for world domination...

What have we come up with?

Port model hooks up an interface from one component to another

Ports preserve the high-performance of direct connections plus versatility of distributed object systems

Generalized ports and the provides/uses design pattern for coupling components

Where are we going?

BoneYard

An IDL compiler automatically generates “glue” code for supported languages

Ports can be used to characterize potential links to other components

CCA is a component architecture that does not dictate frameworks or runtime

Where are we? Details of the CCA specification ...

Programmer can create a new Port by tying methods to a Port

Conclusions

SPMD view ...

What is a software framework and components

Characteristics of Component Arch’s

Language interoperability is a critical first step towards software interoperability

CCA Ports employ a Uses/Provides design pattern for connections

Where we are going ...

Command-line applet that implements the specification

By definition components are software modules that are composable...

ESI is a multi-lab effort writing an equation- solver component specification

Equation Solver Interface (ESI) group is defining interfaces for solvers

The goal of CCA group is enable applications constructed entirely of components

gPorts connect component interfaces in a data-flow-like way

Where we are now ...

Conclusion

Programmer can create a new Port by tying methods to a port

CCA Plans: A Big Picture

IDL specification for the SMG structured multigrid preconditioner from hypre

Common Component Architecture Working Group

CCA Active Participants *

gPort model hooks up an interface from one component to another

User applications can now invoke hypre routines from both C and Fortran 77
