US 12,111,683 B2 · Time calibration for a multi-socket computing system

Abstract

A thread executing a task at a node in a multi-socket computing system may access a first data structure to obtain a first calibration dataset for the node. The first thread may generate a timestamp based on the first calibration dataset and a first quantity of time measured by a clock at the first node. The real-time duration of the task may be determined based on the timestamp. The first thread may recalibrate the first clock by at least generating, based on the first quantity of time measured by the clock and a second quantity of time measured by a wall clock of an operating system of the multi-socket computing system, a second calibration dataset. The first thread may update the first data structure to include the second calibration dataset while a second thread accesses a second data structure to obtain calibration data.

Dependent claims

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.
