20 Claims

1. A system, comprising:

at least one data processor; and

at least one memory storing instructions, which when executed by the at least one data processor, result in operations comprising:

generating, by a first thread executing a first task at a first node in a multi-socket computing system, a first timestamp based at least on a first calibration dataset for the first node and a first quantity of time measured by a first clock at the first node; and

recalibrating, by the first thread, the first clock at the first node, the recalibrating includes generating, based at least on a second quantity of time measured by a second clock of an operating system of the multi-socket computing system, a second calibration dataset describing a relationship between the second quantity of time and the first quantity of time.
