The examples herein describe techniques to generate a dataflow graph using source code to define kernels and communication links between those kernels. In one embodiment, the dataflow graph is formed by using nodes (e.g., kernels) communicably coupled by edges (e.g., communication links between kernels). A compiler converts the source code into a bitstream and / or binary code such that a heterogeneous processing system of a SoC is configured to execute the graph. The compiler uses the graph expressed in the source code to determine where to allocate the kernels in the heterogeneous processing system. Furthermore, the compiler can select specific communication techniques to establish the communication links between the kernels and whether synchronization should be used in the communication links. Thus, a programmer can express a dataflow graph at a high level (using source code) without needing to understand how to implement the computation graph by using the heterogeneous hardware in the SoC.
