System of heterogeneous reconfigurable processors for the data-parallel execution of applications

A method of operating a system for a data-parallel execution of an application on first and second reconfigurable processors having respective first and second layouts, comprising:

• receiving the application;
• retrieving first and second compilation constraints for compiling the application for the first and second reconfigurable processors, respectively, wherein the first compilation constraints are based on the first layout and the second compilation constraints are based on the second layout;
• using the first compilation constraints to generate a first configuration file that is adapted to execute the application on the first reconfigurable processor that is data-parallel compatible with executing the application on the second reconfigurable processor;
• using the second compilation constraints to generate a second configuration file that is adapted to execute the application on the second reconfigurable processor that is data-parallel compatible with executing the application on the first reconfigurable processor;
• loading the first and second configuration files into the first and second reconfigurable processors, respectively;
• and
• starting a data-parallel execution of the application as a first execution on the first reconfigurable processor and a second execution on the second reconfigurable processor.

A computer-implemented method for performing data-parallel executions of an application on a reconfigurable computing system that comprises a plurality of reconfigurable processors having at least first and second layouts, the first layout imposing first constraints for the data-parallel execution of the application and the second layout imposing second constraints for the data-parallel execution of the application, wherein the first and second layouts are different, and wherein at least a subset of the first and second constraints is different, and wherein the reconfigurable computing system further comprises a plurality of data transfer resources that interconnects reconfigurable processors in the plurality of reconfigurable processors and enables the reconfigurable processors in the plurality of reconfigurable processors to receive and send data, comprising:

• compiling the application based on the first constraints into a first configuration file and compiling the application based on the second constraints into a second configuration file, wherein the first configuration file is adapted to be executed on first reconfigurable processors of the plurality of reconfigurable processors having the first layout, and wherein the second configuration file is adapted to be executed on second reconfigurable processors of the plurality of reconfigurable processors having the second layout;
• using the first and second configuration files to configure the first and second reconfigurable processors, respectively;
• executing the application on the first reconfigurable processors in a first implementation of the application;
• and
• executing the application on the second reconfigurable processors in a second implementation of the application, wherein the first and second implementations of the application are data-parallel compatible.
