Abstract: Disclosed embodiments relate to a system with configurable cache sub-domains and cross-die memory coherency. In one example, a system includes R racks, each rack housing N nodes, each node incorporating D dies, each die containing C cores and a die shadow tag, each core including P pipelines and a core shadow tag, each pipelines associated with a data cache and data cache tags and being either non-coherent or coherent and one of X coherency domains, wherein each pipeline, when needing to read a cache line, issues a read request to its associated data cache, then, if need be, issues a read request to its associated core-level cache, then, if need be, issues a read request to its associated die-level cache, then, if need be, issues a no-cache remote read request to a target die being mapped to hold the cache line.

Abstract: Embodiments of apparatuses and methods for copying and operating on matrix elements are described. In embodiments, an apparatus includes a hardware instruction decoder to decode a single instruction and execution circuitry, coupled to hardware instruction decoder, to perform one or more operations corresponding to the single instruction. The single instruction has a first operand to reference a base address of a first representation of a source matrix and a second operand to reference a base address of second representation of a destination matrix. The one or more operations include copying elements of the source matrix to corresponding locations in the destination matrix and filling empty elements of the destination matrix with a single value.

Abstract: Disclosed embodiments relate to an improved memory system architecture for multi-threaded processors. In one example, a system includes a system comprising a multi-threaded processor core (MTPC), the MTPC comprising: P pipelines, each to concurrently process T threads; a crossbar to communicatively couple the P pipelines; a memory for use by the P pipelines, a scheduler to optimize reduction operations by assigning multiple threads to generate results of commutative arithmetic operations, and then accumulate the generated results, and a memory controller (MC) to connect with external storage and other MTPCs, the MC further comprising at least one optimization selected from: an instruction set architecture including a dual-memory operation; a direct memory access (DMA) engine; a buffer to store multiple pending instruction cache requests; multiple channels across which to stripe memory requests; and a shadow-tag coherency management unit.

Abstract: Embodiments of apparatuses, methods, and systems for scheduling tasks to hardware threads are described. In an embodiment, a processor includes a multiple hardware threads and a task manager. The task manager is to issue a task to a hardware thread. The task manager includes a hardware task queue to store a descriptor for the task. The descriptor is to include a field to store a value to indicate whether the task is a single task, a collection of iterative tasks, and a linked list of tasks.

Abstract: Technology described herein provides a dynamically reconfigurable processing core. The technology includes a plurality of pipelines comprising a core, where the core is reconfigurable into one of a plurality of core modes, a core network to provide inter-pipeline connections for the pipelines, and logic to receive a morph instruction including a target core mode from an application running on the core, determine a present core state for the core, and morph, based on the present core state, the core to the target core mode. In embodiments, to morph the core, the logic is to select, based on the target core mode, which inter-pipeline connections are active, where each pipeline includes at least one multiplexor via which the inter-pipeline connections are selected to be active. In embodiments, to morph the core, the logic is further to select, based on the target core mode, which memory access paths are active.

Abstract: Embodiments of apparatuses, methods, and systems for a multithreaded processor core with hardware-assisted task scheduling are described. In an embodiment, a processor includes a first hardware thread, a second hardware thread, and a task manager. The task manager is to issue a task to the first hardware thread. The task manager includes a hardware task queue in which to store a plurality of task descriptors. Each of the task descriptors is to represent one of a single task, a collection of iterative tasks, and a linked list of tasks.
