Abstract: A system and method for transmitting state based input over a network are presented. Embodiments of the present invention are operable to generate vector data comprising a composite of all state data associated with the state of all user input claims of a client system and transmit the vector data from the client device to a host device over a network. Embodiments of the present invention are further operable at the host device to determine a simulated input state at the client side by performing a comparison of the vector data currently received to a last known vector data and rendering output in response to the comparison.

Abstract: In one embodiment of the present invention a driver configures a graphics pipeline implemented in a cache tiling architecture to perform dynamically-defined multi-pass rendering sequences. In operation, based on sequence-specific configuration data, the driver determines an optimized tile size and, for each pixel in each pass, the set of pixels in each previous pass that influence the processing of the pixel. The driver then configures the graphics pipeline to perform per-tile rendering operations in a region that is translated by a pass-specific offset backward—vertically and/or horizontally—along a tiled caching traversal line. Notably, the offset ensures that the required pixel data from previous passes is available. The driver further configures the graphics pipeline to store the rendered data in cache lines.

Abstract: A method, computer program product, and system perform computations using a sparse convolutional neural network accelerator. A first vector comprising only non-zero weight values and first associated positions of the non-zero weight values within a 3D space is received. A second vector comprising only non-zero input activation values and second associated positions of the non-zero input activation values within a 2D space is received. The non-zero weight values are multiplied with the non-zero input activation values, within a multiplier array, to produce a third vector of products. The first associated positions are combined with the second associated positions to produce a fourth vector of positions, where each position in the fourth vector is associated with a respective product in the third vector. The products in the third vector are transmitted to adders in an accumulator array, based on the position associated with each one of the products.

Abstract: One embodiment of the present invention sets forth a technique for increasing available storage space within compressed blocks of memory attached to data processing chips, without requiring a proportional increase in on-chip compression status bits. A compression status bit cache provides on-chip availability of compression status bits used to determine how many bits are needed to access a potentially compressed block of memory. A backing store residing in a reserved region of attached memory provides storage for a complete set of compression status bits used to represent compression status of an arbitrarily large number of blocks residing in attached memory. Physical address remapping (“swizzling”) used to distribute memory access patterns over a plurality of physical memory devices is partially replicated by the compression status bit cache to efficiently integrate allocation and access of the backing store data with other user data.

Abstract: A subsystem is configured to support a distributed instruction set architecture with primary and secondary execution pipelines. The primary execution pipeline supports the execution of a subset of instructions in the distributed instruction set architecture that are issued frequently. The secondary execution pipeline supports the execution of another subset of instructions in the distributed instruction set architecture that are issued less frequently. Both execution pipelines also support the execution of FFMA instructions as well as a common subset of instructions in the distributed instruction set architecture. When dispatching a requested instruction, an instruction scheduling unit is configured to select between the two execution pipelines based on various criteria. Those criteria may include power efficiency with which the instruction can be executed and availability of execution units to support execution of the instruction.

Abstract: A method, computer readable medium, and system are disclosed for inline data inspection.

Abstract: A simulation engine performs a mass-conserving Eulerian fluid simulation by manipulating the distribution of density between nodes associated with the fluid simulation. The simulation engine traces a velocity field upstream to identify the source of mass that currently resides at a given node. The simulation engine then adjusts (i) the density contributions to that source from adjacent nodes and (ii) the density contributions provided by that source to the given node. In doing so, the simulation engine maintains conservation of mass at a local level between nodes within a given neighborhood. As a result, mass is conserved at a global level. One advantage of the disclosed technique is that a fluid interface associated with the fluid simulation may appear physically realistic, because numerical errors typically caused by violations of conservation of mass may be eliminated.
