The goal of this project is to enhance the overall productivity of applications science on diverse high performance computing (HPC) platforms by conducting research in two innovative software environments. The first is a virtualized command toolkit (VCT) for application building and execution that provides a common view across diverse HPC systems. The VCT consists of a software backplane architecture that presents a uniform but extensible interface for preparatory and pre-execution stages of application execution, which interfaces to instance-specific software via customizable plug-in modules.
The second is a next generation runtime environment (RTE) that similarly provides a flexible, adaptive framework for plugging in modules optimized for a specific HPC system and allows dynamic interfacing to a variety of user environments. Both these environments employ platform specific pluggable modules disseminating target-specific knowledge and expertise immediately to all end-users who can continue to interface to a familiar environment.
