US 2026/0312914 A1 · FLOW CONTROL-BASED COMPUTING SYSTEM AND METHOD FOR SWITCHING CONNECTIONS BETWEEN COMPUTING RESOURCES

Abstract

A computing system is provided. The computing system may include a first to a third computing resource that transmit and receive a message, data, or a flit based on credits; a switch fabric including a first to a third switch port connected to the first to the third computing resources, respectively; and a fabric manager configured to control the switch fabric to change a one-to-one connection path between the first switch port and the second switch port to a one-to-one connection path between the first switch port and the third switch port. The fabric manager may transmit, to each of the first and second computing resources, a request to stop transmission and reception in order to change the connection path among the plurality of switch ports, and each of the first and second computing resources may stop transmission of the message, the data, or the flit based on the request to stop transmission and reception.

Dependent claims

A computing system comprising:

a first to a third computing resource that transmit and receive a message, data, or a flit based on credits;
a switch fabric including a first to a third switch port connected to ports of the first to the third computing resource, respectively;
and
a fabric manager configured to control the switch fabric to switch a one-to-one connection path between the first switch port and the second switch port to a one-to-one connection path between the first switch port and the third switch port,
wherein the fabric manager transmits, to each of the first and second computing resources, a request to stop transmission and reception in order to switch the connection path among the plurality of switch ports, and
the first computing resource and the second computing resource each stop transmission of the message, the data, or the flit based on the request to stop transmission and reception.

A method for switching connections between a plurality of computing resources that transmit and receive a message, data, or a flit based on credits through a switch fabric including a plurality of switch ports, the method comprising:

determining, by a fabric manager, a start of switching for switching a connection path between a first switch port connected to a first computing resource and a second switch port connected to a second computing resource to a connection path between the first switch port and a third switch port connected to a third computing resource;
transmitting, by the fabric manager, a request to stop transmission and reception to each of the first computing resource and the second computing resource;
stopping, by each of the first computing resource and the second computing resource, transmission of the message, the data, or the flit based on the request to stop transmission and reception;
and
performing, by the switch fabric, the switching.
