Configuration of Application Software on Multi-Core Image Processor

One or more non-transitory computer storage media encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving a request to compute kernel assignments for an image processing pipeline to be executed on a device having a plurality of stencil processors, wherein the image processing pipeline comprises a plurality of kernels;
• generating a plurality of candidate kernel assignments, each candidate kernel assignment assigning each kernel of the image processing pipeline to a respective stencil processor of the plurality of stencil processors;
• computing a total weight for each of the plurality of candidate kernel assignments, the total weight for each candidate kernel assignment being based on respective transfer sizes of data transferred between kernels according to the candidate kernel assignment;
• selecting a candidate kernel assignment according to the respective total weights computed for each of the plurality of candidate kernel assignments;
• and
• assigning kernels of the plurality of kernels to respective stencil processors according to the selected candidate kernel assignment.
