Networked host system for synchronizing multiple subsystems' programs
The patent US12073262B2 describes a host system designed to interface with multiple subsystems, specifically tile computers that function as work accelerators. The host system includes at least one processor and memory for storing computer-readable instructions. These instructions enable the host to compile local programs for each subsystem, which involves defining synchronization groups that consist of at least two subsystems. Each local program contains compute instructions for executing operations during various compute phases and data transfer instructions that facilitate barrier synchronizations at specific execution points. Notably, some of these synchronizations require the host's involvement, allowing for data exchange between the host and the subsystems over a network, which can be an Ethernet network. The data exchange process utilizes multi-stream buffers to manage data belonging to different streams, ensuring efficient communication between the host and subsystems.
Additionally, the patent outlines methods for both the host system and the subsystems to execute local programs and manage data exchanges. The subsystems are equipped with processors and memory to run their respective local programs, which include instructions for compute operations and barrier synchronizations. The data exchange process is designed to occur after sending an initiator of data transfer to the host, with the subsystems synchronizing their buffers with those of the host system. The patent also mentions the use of remote direct memory access (RDMA) to facilitate data exchanges, enhancing the efficiency of communication between the host and subsystems. Overall, the patent presents a structured approach to managing distributed computing tasks across multiple subsystems, emphasizing synchronization and data exchange mechanisms.
