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.
