Summary:In a first aspect, a first method of synchronizing a plurality of processors of a system is provided. The first method includes the steps of (1) modifying a peripheral component interconnect express (PCIe) protocol to include a completion status encode associated with a synchronization command that indicates whether a condition of the synchronization command is met; (2) providing a system including (a) a memory; (b) a first processor coupled to the memory; (c) a second processor; and (d) an interconnect coupling the second processor to the first processor and the memory; and (3) employing the modified PCIe protocol on the interconnect. Numerous other aspects are provided.
