Systems and methods are disclosures for scheduling code in a multiprocessor system. Code is portioned into code blocks by a compiler. The compiler schedules execution of code blocks in nodes. The nodes are connected in a directed acyclical graph with a top node, terminal node and a plurality of intermediate nodes. Execution of the top node is initiated by the compiler. After executing at least one instance of the top node, an instruction in the code block indicates to the scheduler to initiate at least one intermediary node. The scheduler schedules a thread for execution of the intermediary node. The data for the nodes resides in a plurality of data buffers; the index to the data buffer is stored in a command buffer.

Configurable scheduler for graph processing on multi-processor computing systems

The described embodiments include systems, methods, and apparatuses for increased efficiency processing flow. One method includes a plurality of stages configured to process an execution graph that includes a plurality of logical nodes with defined properties and resources associated with each logical node of the plurality of logical nodes, a recirculating ring buffer, wherein the recirculating ring buffer is configured to holding only any one of a control information, input, and, or out data necessary to stream a temporary data between each logical node of the execution graph, and a data producer, wherein the data producer is configured to stall from writing control information into a command buffer upon the command buffer being full, preventing command buffer over-writing.

Node topology employing command and data buffers for executing thread scheduling

Systems, apparatuses and methods are disclosed for scheduling threads comprising of code blocks in a graph streaming processor (GSP) system. One system includes a scheduler for scheduling plurality of threads, the plurality of threads includes a set of instructions operating on the graph streaming processors of GSP system. The scheduler comprises a plurality of stages where each stage is coupled to an input command buffer and an output command buffer. A portion of the scheduler is implemented in hardware and comprises of a command parser operative to interpret commands within a corresponding input command buffer, a thread generator coupled to the command parser operate to generate the plurality of threads, and a thread scheduler coupled to the thread generator for dispatching the plurality of threads for operating on the plurality of graph streaming processors.

The claimed invention discloses system comprising a plurality of logical nodes comprised in a single or plurality of stages, with defined properties and resources associated with each node, for reducing compute resources, said system further comprising: at least a recirculating ring buffer holding only any one of a control information, input, and, or out data necessary to stream a temporary data between node and, or nodes in an execution graph, thereby reducing size of said recirculating ring buffer; said recirculating ring buffer being sufficiently reduced in size to reside in an on-chip cache, such that any one of the control information, input, and, or out data between node and, or nodes need not be stored in memory; wherein the control information further comprises a command related to invalidating any one of the input and, or out data held in a recirculating ring data buffer, clearing the buffer of tasked data; and wherein a producer is stalled from writing any more control information into a recirculating ring command buffer upon the buffer being full, preventing command buffer over-writing, and thereby reducing compute resources associated with a DRAM memory transaction.

Methods, systems and apparatuses for selecting graphics data of a server system for transmission are disclosed. One method includes reading data from memory of the server system, checking if the data is being read for the first time, checking if the data was written by a processor of the server system during processing, comprising checking if the data is available on a client system or present in a transmit buffer, placing the data in the transmit buffer if the data is being read for the first time and was not written by the processor during the processing as determined by the checking if the data was written by the processor of the server system during processing, wherein if the data is being read for the first time and was written by the processor of the server system during processing the data is not placed in the transmit buffer.

Selecting data of a server system for transmission

Embodiments disclosed include a mechanism in a system and method for significantly reducing power consumption by reducing computation and bandwidth. This mechanism is particularly applicable for modern 3D synthetic images which contain high pixel overdraw and dynamically generated intermediates images. Only blocks of computation which contribute to the final image are performed. This is accomplished by rendering in reverse order and by performing multiple visibility sort in a streaming fashion through the pipeline. Rendering of dynamically generated intermediate images is performed sparsely by projecting texture coordinates from a current image back into one or more dependent images in a recursive manner. The newly computed pixel values are then filtered and control is returned to the sampling shader of the current image. When only visible pixels are projected optimal computation is performed. Several implementations are presented with increasing efficiency. An acceleration structure, termed a Draw Buffer, simplifies the process of projecting backward and utilizes a hardware managed dynamic memory object. This mechanism reduces computation by 50%, with significant bandwidth and power savings.

Processing of graphics data of a server system for transmission

Provided are a method and system for loading test data into execution units in a graphics card to test the execution units. Test instructions are loaded into a cache in a graphics module comprising multiple execution units coupled to the cache on a bus during a design test mode. The cache instructions are concurrently transferred to an instruction queue of each execution unit to concurrently load the cache instructions into the instruction queues of the execution units. The execution units concurrently execute the cache instructions to fetch test instructions from the cache to load into memories of the execution units and execute during the design test mode.
