A moderate complexity task such as writing a JPEG codec requires understanding of Huffman coding, discrete cosine transform and a number of other minor concepts. Right now am working on a physically distributed, synchornized system. It has some signal processing code: cross-correlation, FFT. The process planner builds spanning trees out of the layout graph to execute the tasks.
