Network device, system, and method of operating cxl switching device for synchronizing data

A method of operating a compute express link (CXL) switching device, the method comprising:

• receiving a plurality of packets and at least one interrupt signal from a plurality of CXL processing devices, wherein each of the plurality of packets includes vector data and characteristic data associated with the vector data;
• synchronizing the vector data, the synchronizing including performing a calculation operation on the vector data based on the plurality of packets and the interrupt signal;
• and
• outputting the synchronized vector data to the plurality of CXL processing devices.

A network device comprising:

• memory configured to store vector data of a plurality of packets received from a plurality of processing devices;
• and
• processing circuitry configured to,
• store at least one instruction signal in the memory based on characteristic data of the plurality of packets in response to a plurality of interrupt signals received from the plurality of processing devices,
• determine a calculation operation type based on at least one instruction signal stored in the memory,
• synchronize vector data stored in the memory, the synchronizing including performing the calculation operation on the vector data based on the determined calculation operation type, and
• output the synchronized vector data.
