Abstract: A gateway for interfacing a host with a subsystem for acting as a work accelerator to the host. The gateway enables the transfer of batches of data to the subsystem at precompiled data exchange synchronisation points. The gateway comprises a streaming engine having a data mover engine and a memory management engine, the data mover engine and memory management engine being configured to execute instructions in coordination from work descriptors. The memory management engine is configured to execute instructions from the work descriptor to transfer data between external storage and the local memory associated with the gateway. The data mover engine is configured to execute instructions from the work descriptor to transfer data between the local memory associated with the gateway and the subsystem.

Abstract: A gateway for interfacing a host with a subsystem for acting as a work accelerator to the host, the gateway enabling the transfer of batches of data to and from the subsystem at precompiled data exchange synchronisation points attained by the subsystem. The gateway is configured to: receive from a storage system data determined by the host to be processed by the subsystem; store a number of credits indicating the availability of data for transfer to the subsystem at each pre-compiled data exchange synchronisation point; receive a synchronisation request from the subsystem when it attains a data exchange synchronisation point; and in response to determining that the number of credits comprises a non-zero number of credits: transmit a synchronisation acknowledgment to the subsystem; and cause the received data to be transferred to the subsystem.

Abstract: A gateway for use in a computing system to interface a host with the subsystem for acting as a work accelerator to the host, the gateway having: an accelerator interface for connection to the subsystem to enable transfer of batches of data between the subsystem and the gateway; a data connection interface for connection to external storage for exchanging data between the gateway and storage; a gateway interface for connection to at least one second gateway; a memory interface connected to a local memory associated with the gateway; and a streaming engine for controlling the streaming of batches of data into and out of the gateway in response to pre-compiled data exchange synchronisation points attained by the subsystem, wherein the streaming of batches of data are selectively via at least one of the accelerator interface, data connection interface, gateway interface and memory interface.
