Abstract: A system simulator simulates operations of a plurality of interconnected devices in a simulation of a computing system. The system simulator implements a communication runtime in the simulation to receive a packet generated by a simulation of a first one of the plurality of devices to be sent to a simulation of a second one of the plurality of devices in the simulation. The communication runtime buffers the packet in its internal buffer and receives a query from the simulation of the second device based on buffer capacity in the simulation of the second device has capacity. The packet is sent from the communication runtime buffer to the simulation of the second device based on the query to simulate transmission of the packet from the first device to the second device on a link.

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: A distributed simulation system is provided that includes a plurality of computing nodes interconnected via a network implementing a Message Passing Interface (MPI) protocol. Each computing node is to simulate hardware logic of a core of a graph processing system and to simulate a respective system memory portion of the graph processing system.
