Abstract: Disclosed is a communication method, a zone scheduler performing thereof, and an inter-zone scheduling coordinator (IZSC). A communication method performed by a zone scheduler may include transmitting an inter-zone scheduling request to an IZSC in response to an occurrence of an inter-zone traffic with respect to another zone scheduler, receiving an inter-zone matching pattern and information on a time slot from the IZSC, and transmitting the inter-zone traffic to the other zone scheduler by performing scheduling based on the inter-zone matching pattern in the time slot.

Abstract: A system for cooperation of disaggregated computing resources interconnected through an optical circuit, and a method for cooperation of disaggregated resources are disclosed. Functional block devices such as a processor block, an accelerator block, and a memory fabric block exist at a remote location, and these three types of remote functional block devices are interconnected and interoperated in a specific program to perform a cooperative computation and processing process. Accordingly, the system shares data and information of a memory existing in each block through optical signal interconnection that provides low-latency, fast processing, and wide bandwidth, and maintains cooperation and memory coherency.
