Hi Tommy, This is a pretty complicated question to answer in an email. The best thing to do is look at the code to figure things out. You'll want to start with gr_block_executor to see how the scheduler moves data between blocks and calls the work function. Then gr_buffer and gr_buffer_reader will show you how the buffer read and write pointers are handled. But yes, currently, the structure of blocks in a flowgraph require shared memory to work.
