Parallel Application Porting by Means of Soft-Architectures

In the paper we consider a method of porting of parallel applications to various reconfigurable computer systems with different soft-architectures and configurations. Our method of porting of parallel applications by means of soft-architectures contains a procedure of analysis and comparison of objects of the initial and the target soft-architectures, a procedure of analysis and comparison of connections of the ported parallel application and the target soft-architecture, a procedure which generates recommendations for modification of the target soft-architecture for successful porting. Together these procedures provide porting of the application to the target soft-architecture without additional modification and debugging of the application, and if porting is impossible the developer gets recommendations for modification of the target soft-architecture. Owing to this, it is possible to port the application, to simplify modification of the target soft-architecture and to reduce considerably the porting time. Owing to our new porting method, the parallel application is ported to a new soft-architecture without any additional modification of its source code, and its information graph is automatically mapped on various soft-architectures.
