Technologies for internal time syncrhonization

A method for internal time synchronization of a compute device, the method comprising:

• reading, by the compute device, a counter value from a counter of an always running timer of the compute device;
• generating, by the compute device, a timestamp value based on the counter value of the always running timer;
• broadcasting, by the compute device, the timestamp value on a serial broadcast wire at a frequency of a first clock;
• sampling, by the compute device, a signal indicative of the timestamp value broadcasted on the serial broadcast wire;
• updating, by the compute device and based on the sampled signal, a counter of a local always running timer of a network card of the compute device;
• capturing, by the compute device, a snapshot of a counter of a system timer of the network interface card;
• capturing, by the compute device, a snapshot of the counter of the local always running timer, wherein capturing the snapshot of the local always running timer comprises sampling the local always running timer at a frequency of a second clock, wherein the frequency of the second clock is at least twice the frequency of the first clock;
• determining, by the compute device and based on the oversampled snapshot of the counter of the local always running timer, a phase of the local always running timer relative to the system timer;
• and
• storing an indication of the snapshot of the counter of the system timer, an indication of the snapshot of the counter of the local always running timer, and an indication of the phase of the local always running timer.

One or more non-transitory computer-readable media comprising a plurality of instructions stored thereon that, when executed, causes a compute device to:

• read a counter value from a counter of an always running timer of the compute device;
• generate a timestamp value based on the counter value of the always running timer;
• and
• broadcast the timestamp value on a serial broadcast wire at a frequency of a first clock;
• sample a signal indicative of the timestamp value broadcasted on the serial broadcast wire;
• update, based on the sampled signal, a counter of a local always running timer of a network card of the compute device;
• capture a snapshot of a counter of a system timer of the network interface card;
• capture a snapshot of the counter of the local always running timer, wherein to capture the snapshot of the local always running timer comprises to sample the local always running timer at a frequency of a second clock, wherein the frequency of the second clock is at least twice the frequency of the first clock;
• determine, based on the oversampled snapshot of the counter of the local always running timer, a phase of the local always running timer relative to the system timer;
• and
• store an indication of the snapshot of the counter of the system timer, an indication of the snapshot of the counter of the local always running timer, and an indication of the phase of the local always running timer.
