Methods, systems. and apparatuses for graph streaming processing are disclosed. One method includes receiving, by a thread scheduler, a group of threads, calculating a resource requirement for execution of the group of threads, calculating resource availability in a plurality of processors of each of a plurality of processor arrays, dispatching the group of threads to a selected one of plurality of processors of processor arrays, scheduling a group load instruction for all threads of the group of threads, including loading into a group load register a subset of inputs of the input tensor for processing of each thread of the group of threads, wherein the group load register provides the subset of the inputs of the input tensor to the group of threads of the selected one of the plurality of processors, wherein all threads of the group of threads are synchronized when executing the group load instruction.

Group thread dispatch for graph streaming processor

Methods, systems, and apparatuses for graph stream processing are disclosed. One apparatus includes a cascade of graph streaming processors, wherein each of the graph streaming processor includes a processor array, and a graph streaming processor scheduler. The cascade of graph streaming processors further includes a plurality of shared command buffers, wherein each shared command buffer includes a buffer address, a write pointer, and a read pointer, wherein for each of the plurality of shared command buffers a graph streaming processor writes commands to the shared command buffer as indicated by the write pointer of the shared command buffer and the graph streaming processor reads commands from the shared command buffer as indicated by the read pointer, wherein 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.

Cascading of graph streaming processors

Methods, systems, and apparatuses for graph stream processing are disclosed. One apparatus includes a cascade of graph streaming processors, wherein each of the graph streaming processor includes a processor array, and a graph streaming processor scheduler. The cascade of graph streaming processors further includes a plurality of shared command buffers, wherein each shared command buffer includes a buffer address, a write pointer, and a read pointer, wherein for each of the plurality of shared command buffers a first graph streaming processor writes commands to the shared command buffer as indicated by the write pointer of the shared command buffer and a second graph streaming processor reads commands from the shared command buffer as indicated by the read pointer, wherein 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.

Methods, systems, and apparatuses for graph streaming processing system are disclosed. One system includes a plurality of graph streaming processors operative to process a plurality of threads, wherein the plurality of threads is organized as nodes. The system further includes a scheduler that includes a plurality of stages. Each stage includes a command parser operative to interpret commands within a corresponding input command buffer, an alternate command buffer, and a thread generator coupled to the command parser. The thread generator is operative to generate the plurality of threads, and dispatch the plurality of threads, where the processing of the plurality of thread for each stage includes storing write commands in the corresponding output command buffer or in the alternate command buffer.

Reduction of a number of stages of a graph streaming processor

Methods, systems and apparatuses for graph processing are disclosed. One graph streaming processor includes a thread manager, wherein the thread manager is operative to dispatch operation of the plurality of threads of a plurality of thread processors before dependencies of the dependent threads have been resolved, maintain a scorecard of operation of the plurality of threads of the plurality of thread processors, and provide an indication to at least one of the plurality of thread processors when a dependency between the at least one of the plurality of threads that a request has or has not been satisfied. Further, a producer thread provides a response to the dependency when the dependency has been satisfied, and each of the plurality of thread processors is operative to provide processing updates to the thread manager, and provide queries to the thread manager upon reaching a dependency.
