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: Examples described herein relate to a network interface device that includes a direct memory access (DMA) circuitry; a network interface; at least two host interfaces to simultaneously connect to multiple platforms; an interface to a memory device; and circuitry. In some examples, at least two of the multiple platforms include a processor and a memory coupled to a circuit board. In some examples, the circuitry is to: based on a level of security classification of a second platform of the multiple platforms, perform secure transfer of data from a first platform of the multiple platforms to the second platform of the multiple platforms and enforce rules for data access and data transfer by the multiple platforms.

Abstract: Disclosed embodiments relate to an instruction set architecture to facilitate energy-efficient computing for exascale architectures. In one embodiment, a processor includes a plurality of accelerator cores, each having a corresponding instruction set architecture (ISA); a fetch circuit to fetch one or more instructions specifying one of the accelerator cores, a decode circuit to decode the one or more fetched instructions, and an issue circuit to translate the one or more decoded instructions into the ISA corresponding to the specified accelerator core, collate the one or more translated instructions into an instruction packet, and issue the instruction packet to the specified accelerator core; and, wherein the plurality of accelerator cores comprise a memory engine (MENG), a collective engine (CENG), a queue engine (QENG), and a chain management unit (CMU).
