Cascading of graph streaming processors

A cascade of graph streaming processors, comprising:

• a plurality of graph streaming processors, wherein each of the graph streaming processor comprises:
• a processor array including a plurality of processors;
• a thread manager, the thread manager comprising a plurality of stages and a plurality of command buffers located between each of the plurality of stages, wherein each stage includes physical hardware operative to schedule each of a plurality of threads of the stage for processing on the processor array, including an input command buffer parser operative to interpret commands within a corresponding input command buffer and generate the plurality of threads;
• the cascade of graph streaming processors further comprising;
• one or more shared command buffers located between each of the plurality of graph streaming processors, wherein each shared command buffer includes a buffer address, a write pointer, and a read pointer;
• wherein
• for each of the shared command buffers a first graph streaming processor of the plurality of graph streaming processors operates to write commands to the shared command buffer as indicated by the write pointer of the shared command buffer and a second graph streaming processor of the plurality of graph streaming processors operates to read commands from the shared command buffer as indicated by the read pointer by interpreting commands of the shared command buffer by an input command buffer parser of a first stage of the second graph streaming processor;
• wherein for each one of the shared command buffers, at least one graph streaming processor scheduler operates to manage the write pointer and the read pointer to avoid overwriting unused commands of the shared command buffer.
