摘要： Loading data from a computer memory system is disclosed. A memory system is provided, wherein some or all data stored in the memory system is organized as one or more pointer-linked data structures. One or more iterator registers are provided. A first pointer chain is loaded, having two or more pointers leading to a first element of a selected pointer-linked data structure to a selected iterator register. A second pointer chain is loaded, having two or more pointers leading to a second element of the selected pointer-linked data structure to the selected iterator register. The loading of the second pointer chain reuses portions of the first pointer chain that are common with the second pointer chain.Modifying data stored in a computer memory system is disclosed. A memory system is provided. One or more iterator registers are provided, wherein the iterator registers each include two or more pointer fields for storing two or more pointers that form a pointer chain leading to a data element. A local state associated with a selected iterator register is generated by performing one or more register operations relating to the selected iterator register and involving pointers in the pointer fields of the selected iterator register. A pointer-linked data structure is updated in the memory system according to the local state.

摘要： A physical layer (PHY) is coupled to a serial, differential link that is to include a number of lanes. The PHY includes a transmitter and a receiver to be coupled to each lane of the number of lanes. The transmitter coupled to each lane is configured to embed a clock with data to be transmitted over the lane, and the PHY periodically issues a blocking link state (BLS) request to cause an agent to enter a BLS to hold off link layer flit transmission for a duration. The PHY utilizes the serial, differential link during the duration for a PHY associated task selected from a group including an in-band reset, an entry into low power state, and an entry into partial width state

摘要： A system includes a set-associative storage container and a processor configured to generate a vector that is a random number. Two or more residue functions are applied to the vector that each produces a state signal including a different number of states based on the vector. A set status is determined that identifies whether each set of the set-associative storage container is enabled or disabled. One of the state signals is selected that has a same number of states as a number of the sets that are enabled. The selected state signal is mapped to the sets that are enabled to assign each of the states of the selected state signal to a corresponding one of the sets that are enabled. A set selection of the set-associative storage container is output based on the mapping to randomly select one of the sets that are enabled from the set-associative storage container.

摘要： A photonics-optimized multi-processor system may include a plurality of processor chips, each of the processor chips comprising at least one input/output (I/O) component. The multi-processor system may also include first and second photonic components. The at least one I/O component of at least one of the processor chips may be configured to directly drive the first photonic component and receive a signal from the second photonic component. A total latency from any one of the processor chips to data at any global memory location may not be dominated by a round trip speed-of-light propagation delay. A number of the processor chips may be at least 10,000, and the processor chips may be packaged into a total volume of no more than 8 m3. A density of the processor chips may be greater than 1,000 chips per cubic meter.

摘要： A method and apparatus for performing non-temporal write combining using existing cache resources is disclosed. In one embodiment, a method includes executing a first thread on a processor core, the first thread including a first block initialization store (BIS) instruction. A cache query may be performed responsive to the BIS instruction, and if the query results in a cache miss, a cache line may be installed in a cache in an unordered dirty state in which it is exclusively owned by the first thread. The first BIS instruction and one or more additional BIS instructions may write data from the first processor core into the first cache line. After a cache coherence response is received, the state of the first cache line may be changed to an ordered dirty state in which it is no longer exclusive to the first thread.

摘要： A method for controlling cache snoop and/or invalidate coherence traffic for specific caches based on transaction attributes is described. A memory management unit (MMU) determines one or more transaction attributes for a cache coherence transaction from a requesting processor. A routing module identifies a cachability domain and/or shareability domain based on the transaction attributes and routes the cache coherence transaction to one or more caches in the cachability domain and/or shareability domain. Instead of coherence traffic being routed to all caches on a coherence bus, coherence traffic is selectively routed based on transaction attributes such as an address space identifier (ASID), a virtual machine identifier (VMID), a secure bit (NS), a hypervisor identifier (HYP), etc.

摘要： Embodiments of the invention provide a programming model for CPU-GPU platforms. In particular, embodiments of the invention provide a uniform programming model for both integrated and discrete devices. The model also works uniformly for multiple GPU cards and hybrid GPU systems (discrete and integrated). This allows software vendors to write a single application stack and target it to all the different platforms. Additionally, embodiments of the invention provide a shared memory model between the CPU and GPU. Instead of sharing the entire virtual address space, only a part of the virtual address space needs to be shared. This allows efficient implementation in both discrete and integrated settings.
