CORRELATION TECHNIQUE FOR DETERMINING RELATIVE TIMES OF ARRIVAL/DEPARTURE OF CORE INPUT/OUTPUT PACKETS WITHIN A MULTIPLE LINK-BASED COMPUTING SYSTEM

摘要

A method is described that comprises receiving a timing exposure packet having timestamp information. The timestamp information identifies a cycle of a clock signal at which the packet was made available for transfer from a core to a physical layer within a component of a link-based computing system. The packet having been transmitted from the physical layer and also having phase information. The phase information identifies a cycle of the clock signal at which the packet was transferred from the core to the physical layer.
